The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

. . . these are young coconuts. First you drink the fresh coconut-water with a straw through a small hole. Then the coconut is cut in the middle and you can eat the young flesh with a spoon like a soft-cream. Very tasty - very delicious - very healthy

__________________

 

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

Previously spotted by James ('Jawz Diesel'). The colour comes up as "yellow", so could it be an ex-AA truck?

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

. . . this are young coconuts. They are sold for drinking the fresh and healthy water inside the fruit

_______________________________________

 

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

Jaws Two droppin some knowledge

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

. . . this are young coconuts. They are sold for drinking the fresh and healthy water inside the fruit

_______________________________________

 

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

. . . these are young coconuts. First you drink the fresh coconut-water with a straw through a small hole. Then the coconut is cut in the middle and you can eat the young flesh with a spoon like a soft-cream. Very tasty - very delicious - very healthy

__________________

 

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.

 

WIKIPEDIA

V. — RÈGNE D’ABD AL-MALIK, FILS DE MARWAN L'OMEYYADE DE DAMAS (65/685 — 86/705).

'Abd al-Malik, qui succéda à son père, était un homme sensé, intelligent, instruit, un prince puissant, inspirant la crainte et imposant, énergique dans sa politique, un habile administrateur des affaires temporelles. Ce fut sous son règne que le registre des dépenses et des recettes fut rédigé, non plus en persan, mais en arabe, et que la comptabilité publique fut, pour la première fois, rédigée selon la méthode arabe.[71] Abd al-Malik fut le premier qui interdit à ses sujets de parler beaucoup en présence des khalifes et de leur répondre. Or, jusque-là, grande était leur audace à leur égard, comme nous l'avons montré plus haut. Ce fut lui aussi qui donna sur le peuple pleins pouvoirs à Hadjdjâdj, fils de Yousouf, qui fit une incursion à la Ka’abah et qui tua successivement Mous'ab et son frère 'Abd-Allah, tous deux fils de Zoubair.

  

Entre autres anecdotes relatives à ces événements, on rapporte que lorsque Yazid, fils de Mouâwiya, avait envoyé son année pour combattre le peuple de Médine et pour envahir la Ka'abah, Abd al-Malik en avait éprouvé la plus vive contrariété et avait dit : « Si seulement le ciel pouvait écraser la terre ! » Puis, devenu khalife, il en fit autant, et plus encore. Car il envoya Hadjdjadj pour cerner Ibn Zoubair et pour envahir La Mecque.

  

Avant d'être khalife, Abd al-Malik avait été un des jurisconsultes éminents de Médine. Il était surnommé « la Colombe de la Mosquée », parce qu'il y passait tout son temps à moduler la lecture du Coran. Lorsque son père mourut, et qu'on lui apporta la bonne nouvelle de son élévation au khalifat, il ferma le livre sacré et dit : « Voici l'heure de la séparation entre moi et toi. »

  

Puis il se consacra aux affaires de ce monde, et un jour, parait-il, il dit à Sa'id, [72] fils d'al-Mousayyab : « O Sa'id, j'en suis venu au point que je fais le bien sans en être réjoui, et le mal sans en être affligé. » Sa'id, fils d'al-Mousayyab, lui répondit : « Eh bien ! maintenant la mort du cœur est complète chez toi. »

  

C'est du temps d’Abd al-Malik que furent tués 'Abd-Allah, fils de Zoubair, et son frère Mous'ab, l'émir de l'Iraq.

  

Quant à 'Abd-Allah, fils de Zoubair, il s'était retranché à La Mecque, et avait été proclamé khalife par les habitants du Hedjaz et de l'Iraq. Il était d'une avarice sordide qui l'empêcha de réussir dans ses entreprises. Abd al-Malik envoya contre lui Hadjdjâdj, qui mit le siège devant La Mecque, se servit de balistes pour atteindre la Ka’abah et livra des combats à Abd-Allah. Celui-ci, trahi tant par ses parents que par ses partisans, alla trouver sa mère et lui dit : « O ma mère, j'ai été abandonné par tout le monde, y compris mes fils et mes femmes ; il ne m'est resté que quelques fidèles, et encore ne puis-je compter de leur part que sur une patience momentanée. Or, mes ennemis m'accorderont toutes les faveurs d'ici-bas que je demanderai. Quel est ton avis ? » Elle lui répondit : « Tu te connais mieux que personne. Si tu sais que tu luttes pour une juste cause, poursuis ce que tu as commencé, et ne plie pas ton cou devant les hommes de rien que sont les Omeyyades. Si tu ne veux que les biens de ce monde, quel mauvais serviteur d'Allah tu es, et tu auras été l'artisan de ta propre perte (dans la vie future) et de celle de tes compagnons. Crois-tu t'éterniser dans ce monde ? Mieux vaut la mort ! » Il reprit : « O ma mère, je crains, s'ils me tuent, qu'ils ne me mutilent. — Mon cher enfant, répondit-elle, la brebis, après avoir été égorgée, n'éprouve aucune déception lorsqu'on la dépouille. » Elle ne cessa pas de l'exciter ainsi et par de tels propos, jusqu'à ce qu'il fit une sortie, soutînt une lutte opiniâtre et 169 fût tué. Hadjdjâdj fit porter aussitôt cette heureuse nouvelle à 'Abd al-Malik. Ce fut en l'an 73 (= 692 de J.-C.).[73]

  

Le frère d'Abd-Allah, Mous'ab, fils de Zoubair, émir de l'Iraq, était brave, puissant, comblé d'éloges. Il épousa Soukaina, [74] fille de Hosain, et 'Aïcha, fille de Talha. Il les réunit toutes deux avec lui dans sa maison et elles comptaient parmi les grandes dames, les plus riches et les plus belles. Un jour, Abd al-Malik dit à ses compagnons : « Qui est le plus courageux des hommes ? — Toi, répondirent-ils. — Cela n'est pas, dit le khalife, mais le plus courageux des hommes est celui qui a réuni dans sa maison 'Aïcha, fille de Talha, et Soukaina, fille de Hosain. » Il désignait ainsi Mous'ab.

  

Plus tard, Abd al-Malik, lorsqu'il se prépara à combattre Mou'sab, prit congé de sa femme Atika, [75] fille de Yazid, fils de Mouâwiya. Au moment de la séparation elle pleura, et ses serviteurs pleurèrent en la voyant pleurer. 'Abd al-Malik dit : « Puisse Allah combattre Kouthaiyyîr, [76] l'amoureux d’Azza ! On dirait qu'il a assisté à la scène que voici, lorsqu'il a dit :

  

Veut-il faire une incursion, sa pensée ne s'en laisse point détourner par une femme chaste, qu'orne un collier de perles.

  

Elle lui avait interdit le départ, et, lorsqu'elle a vu l’inutilité de son interdiction, elle a pleuré, et son entourage a pleuré de son affliction.

  

Puis, Abd al-Malik s'élança pour combattre Mous'ab et se rencontra avec lui dans la région du Petit-Tigre. Après un combat acharné, Mous'ab fut tué en l’an 71 (= 690).[77]

  

'Abd al-Malik avait de l’instruction, de la finesse, des qualités éminentes. Cha'bî[78] a dit : « Je ne me suis entretenu avec personne, dont je ne me sois senti le supérieur, à l'exception d'Abd al-Malik, fils de Marvân. Car je ne lui ai jamais raconté une tradition sans qu'il prit ajouter à mes informations, ni un fragment de poésie dont il ne connut le complément.[79] »

  

On dit à Abd al-Malik : « La vieillesse s’est avancée vers toi à pas rapides. — Ce qui ma vieilli, répondit-il, c'est l'abus de la prédication, la crainte de laisser échapper quelque incorrection de langage. » Les incorrections du langage étaient considérées par les Arabes comme la pire des laideurs.

  

Et, entre autres opinions sages qu’Abd al-Malik exprima, je citerai le conseil que, jeune encore, il donna à Mouslim, fils d'Oqba le Mourrite, lorsque celui-ci fut envoyé par Yazid, fils de Mouâwiya, pour combattre les habitants de Médine. Mouslim arriva à cette ville, où les Omeyyades avaient d'abord été bloqués, puis expulsés. Dès qu'il les rencontra, Mouslim, fils d’Oqba, prit conseil d'Abd al-Malik, fils de Marvân, qui était alors un tout jeune homme. « Mon avis, répondit-il, est que tu fasses avancer tes troupes, et lorsque tu seras parvenu aux premiers palmiers de Médine, tu t'y arrêteras ; tes soldats y camperont à l'ombre et mangeront les meilleurs fruits de ces arbres. Le lendemain, dès l'aurore, tu te remettras en marche, tu laisseras Médine à ta gauche, puis tu la contourneras jusqu'à ce que, te dirigeant vers l'est, tu atteignes l'ennemi du côté d'al-Harra. Puis, tu te trouveras en face de tes ennemis ; et à ce moment, lorsque le soleil montera à l'horizon, il sera derrière les épaules de tes compagnons sans leur causer aucun dommage. Bien mieux, il incommodera les Médinois qui verront briller vos casques, les pointes de vos lances, vos épées et vos cottes de mailles, ce que vous ne verrez pas chez eux, tant qu'ils resteront à l'ouest (face au soleil). Puis combats-les, et remets-t'en au secours d'Allah ! »

  

'Abd al-Malik dit, un jour, à ses commensaux : « Que pensez-vous de ce qu'a dit le poète[80] :

  

J'aimerai éperdument Da'd, tant que je vivrai ; et si je meurs, malheur à celui qui l'aimerait éperdument après moi !

  

— Belle idée ! s'écrièrent-ils. — C'est là un mort, dit 'Abd al-Malik, qui dépasse la mesure permise. Je ne trouve point une telle idée bien fine. — Tu as raison, reprirent-ils tous. — Mais comment aurait-il convenu qu'il s'exprimât ?» dit à son tour 'Abd al-Malik. L'un d'eux[81] prit la parole en ces termes : « Il aurait convenu qu'il s'exprimât ainsi :

  

J'aimerai éperdument Da'd, tant que je vivrai ; et si je meurs, je confierai Da'd à qui l'aimera éperdument après moi !

  

— Voilà, dit 'Abd al-Malik, un mort complaisant ! — Comment, demandèrent les commensaux, aurait-il convenu qu'il s'exprimât ? — Comme suit, reprit Abd al-Malik :

  

J'aimerai éperdument Da'd, tant que je vivrai, et si je meurs, puisse Da'd ne faire le bonheur d'aucun amant après moi !

  

— C'est toi, dirent-ils, ô Émir des Croyants, qui es vraiment le plus poète des trois. »

  

Lorsque la maladie d'Abd al-Malik s'aggrava, il dit : « Montez-moi sur une hauteur. » Ils le montèrent sur un endroit élevé, où il se mit à humer l'air, puis il dit : « O vie de ce monde, que tu es douce ! Ta plus longue durée n'est que brièveté, et ce que tu crois donner en grande quantité n'est que misère. Que d'illusions nous nous faisions sur toi ! » Et il appliqua les deux vers suivants :

  

Si tu épluches les comptes, ô mon Maître, ton examen minutieux entraînera un châtiment. Je ne puis supporter le châtiment.

  

Ou, si tu pardonnes, tu seras un Maître miséricordieux pour un homme coupable, dont les péchés sont nombreux comme les grains de poussière.

  

Lorsqu’Abd al-Malik mourut, son fils Walid dit sur lui les prières des morts ; c'est à quoi Hicham, son autre fils, appliqua cette parole :

  

La mort de Qais n'a pas été la mort d'un homme, mais c'est tout l'édifice d'un peuple qui s'est écroulé.[82]

  

Walid dit à Hicham : « Tais-toi, car tu tiens le langage d'un Satan. Que n'as-tu dit, avec l'autre :

  

Lorsqu'un seigneur parmi nous s'en va, il se lève un seigneur qui sait parler comme parlent les nobles, qui sait agir.[83]

  

'Abd al-Malik, fils de Marvân, donna ses instructions à son frère Abd al-’Aziz, lorsque celui-ci se rendit en Egypte comme émir de cette contrée. Il lui dit : « Détends ton visage, montre-toi d'un commerce facile et donne la préférence à la douceur dans le règlement des affaires, car elle te fera plus sûrement atteindre le but. Veille au choix de ton huissier ; qu'il soit parmi les plus excellents de tes serviteurs, car il est ton visage et ta langue. Que personne ne se tienne à ta porte, sans que l'huissier te signale sa présence, afin que ce soit toi-même qui lui accordes une audience ou qui refuses de le recevoir. Lorsque tu sortiras pour tenir ta séance, salue le premier pour qu'on se sente à l'aise avec toi, et l'affection pour toi s'affermira dans les cœurs. Si tu rencontres quelque difficulté, cherche à la surmonter en demandant conseil, car une telle consultation ouvrira ce qui y était lettre close. T'es-tu emporté contre quelqu'un, diffère sa punition, car tu peux plutôt le punir après ce délai que supprimer la punition après qu'elle aura été exécutée. »

  

La mort d’'Abd al-Malik eut lieu en l'an 86 (= 705 de J.-C).

‘Abdel Malik Ibn Marwan

  

‘Abdel Malik Ibn Marwan et né en l’an 26 de l’Hégire (646), la même année où est né Yazid Ibn Mou’awiyah. La mère de ‘Abdel Malik est ‘Ayshah Bint Mou’awiyah Ibn Moughirah Ibn Abi al-‘As Ibn Oumayyah Ibn ‘Abd ash-Shams.

  

L’Imam Ibn Jawzi a dit dans son livre d’Histoire « al-Mountadam fit-Tarikh al-Oumoum wal Moulouk » que ‘Abdel Malik était un savant du Hadith, un poète et qu’il était surnommé « Hamamatoul Masjid », la colombe de la mosquée.

  

On a rapporté que lorsque l’on questionna ‘AbdAllah Ibn ‘Omar (qu’Allah soit satisfait d’eux) :

  

- « Qui devons-nous questionner après vous ? » Il répondit :

  

- « Marwan à un fils savant, consultez-le ! »

  

On a rapporté de Nafi’, le servant de ‘AbdAllah Ibn ‘Omar (qu’Allah soit satisfait d’eux) qu’il a dit :

  

- « Je suis allé à Médine et je n’ai pas vu de jeune rechercher autant la science et aussi fervent adorateur que ‘Abdel Malik Ibn Marwan ».

  

L’Imam Ibn Jawzi a dit dans son livre d’histoire : « Lorsqu’on porta allégeance à ‘Abdel Malik Ibn Marwan, son comportement religieux changea ».

  

En l’an 65 de l’Hégire (684), ‘AbdAllah Ibn Zoubayr (qu’Allah soit satisfait de lui) renvoya ‘AbdAllah Ibn Yazid al-Ansari de son poste de Koufa et le remplaça par le respectable Compagnon ‘AbdAllah Ibn Mouti’ al- ‘Adawi al-Qourayshi (qu’Allah soit satisfait de lui).

  

‘AbdAllah Ibn Mouti’ arriva à Koufa au mois de Ramadan de la même année. Pour rappel, ‘AbdAllah Ibn Mouti’ était le commandant des Qouraysh des gens de Médine, le jour de la bataille de Harra. Il s’était enfuit à La Mecque avait avoir été défait lors de la bataille qui l’opposait à l’armée de Syrie.

  

‘AbdAllah Ibn Mouti’ est né alors que le Prophète (Saluts et Bénédictions d’Allah sur lui) était encore vivant et le Prophète (Saluts et Bénédictions d’Allah sur lui) mâcha une date et lui en frotta le palais (hanakahou).

  

‘AbdAllah Ibn Zoubayr (qu’Allah soit satisfait de lui) renvoya de son poste de gouverneur son frère ‘Oubayd Ibn Zoubayr de Médine et le remplaça par son autre frère Mous’ab Ibn Zoubayr.

  

Moukhtar Ibn Abi ‘Oubayd ath-Thaqafi se rebelle à nouveau

  

A Koufa, Moukhtar Ibn Abi ‘Oubayd ath-Thaqafi, qui était emprisonné, envoya plusieurs lettres aux survivants, qui avaient réussi à fuir après la défaite de ‘AbdAllah Ibn Sourad à la bataille de ‘Ayn al-Warda. Il leur écrivit qu’il voulait venger la mort d’al-Houssayn (qu’Allah soit satisfait d’eux) poursuivre ses assassins.

  

Moukhtar Ibn Abi ‘Oubayd écrivit à ‘AbdAllah Ibn ‘Omar (qu’Allah soit satisfait d’eux) et lui demanda qu’il écrive à ‘AbdAllah Ibn Yazid et Ibrahim Muhammad Ibn Talhah afin qu’ils le libèrent.

  

‘AbdAllah Ibn ‘Omar écrivit donc la lettre et ‘AbdAllah Ibn Yazid le libéra en lui faisant promettre de ne pas chercher à leur disputer le pouvoir ou de se rebeller contre eux.

  

Libéré, Moukhtar Ibn Abi ‘Oubayd rentra chez lui à Koufa et les shi’a se réunirent auprès de lui.

  

Alors, ‘AbdAllah Ibn Zoubayr Ibn al-‘Awwam (qu’Allah soit satisfait d’eux) renvoya de son poste de gouverneur ‘AbdAllah Ibn Yazid et le remplaça par ‘AbdAllah Ibn Mouti’ (qu’Allah soit satisfait de lui).

  

Moukhtar Ibn Abi ‘Oubayd s’employa à réunir les shi’a (partisans) pour soit disant venger al-Houssayn et à attirer Ibrahim Ibn al-Ashtar Nakha’i et son peuple grâce à un faux document qu’il disait être de Muhammad Ibn ‘Ali Ibn Abi Talib (Muhammad al-Hanafiyah).

  

Ce document stipulait que Moukhtar était son partisan, son député, son homme de confiance et son sauveur. Qu’il avait été envoyé pour combattre ses ennemis et pour venger le sang des Gens de la Maisonnée (ahl al-bayt).

  

Le statut de Moukhtar Ibn Abi ‘Oubayd grandit considérablement avec l’arrivée d’Ibrahim Ibn al-Ashtar Nakha’i. La tribu des Nakha fait partie de la puissante tribu des Mathaj, de la tribu des Kahlan, de la tribu des Qahtan.

  

Moukhtar et ses partisans décidèrent de sortir la nuit du jeudi 10 du mois de Rabi’ Awwal de l’année 66 de l’Hégire (685). L’information parvint à ‘AbdAllah Ibn Mouti’ qui lui envoya un détachement pour lui demander de ne pas sortir ni de se révolter.

  

Mais Ibrahim Ibn al-Ashtar Nakha’i qui était un jeune homme courageux sortit avec ses gens pour rejoindre Moukhtar deux jours avant le rendez-vous et il s’ensuivit entre lui et Ilyas Ibn Moudarib, le commandant du détachement envoyé par Ibn Mouti’, un combat ou il tua Ilyas. Cet évènement allait déclencher la révolte plus tôt qu’elle n’avait été prévue et les feux de la guerre s’allumèrent une nouvelle fois à Koufa. Non pas une guerre tribale mais une guerre entre les Musulmans ou plusieurs batailles eurent lieu.

  

Les guerres tribales

  

Durant toutes les précédentes guerres de rebellions, des membres d’une même tribu combattait dans des camps différents et s’entretuaient. Tout comme la période préislamique, le retour des guerres tribales durant le règne des Omeyyades fut une hideuse réalité comme nous allons encore le voir.

  

On a dit que ‘AbdAllah Ibn ‘Aziz al-Kindi et son jeune fils Muhammad était dans l’armée des repentants qui combattit à ‘Ayn al-Warda. Muhammad Ibn ‘AbdAllah Ibn ‘Aziz était un tout jeune enfant qui ne prit pas part au combat du fait de son jeune âge. Lorsque la bataille tourna à leur désavantage, lui et son fils allèrent voir l’armée de Syrie et leur dit :

  

- « O armée de Syrie, y a-t-il parmi vous quelqu’un de la tribu de Kinda ? » Et effectivement, ils se trouvaient des hommes de la tribu yéménite qui sortirent.

  

L’Imam Tabari a rapporté qu’il leur dit :

  

- « Celui-ci est votre frère dit-il, en leur montrant son fils. Prenez-le et ramenez-le à vos proches à Koufa. Je suis ‘AbdAllah Ibn ‘Aziz al-Kindi ». Il lui fut répondu :

  

- « Tu es le fils de nos oncles, la sécurité t’est accordée ! »

  

Mais il refusa leur proposition et décida pour le combat entre eux. Son petit-fils Muhammad pleura et lui demanda de ne pas partir.

  

Les gens pleurèrent avec lui et demandèrent à ‘AbdAllah d’écouter son fils mais petit à petit ‘AbdAllah s’écarta du rang des gens de Syrie, puis, il alla dans les rangs d’une autre tribu et combattit jusqu’à ce qu’il fut tué.

  

Pareillement, lors de la guerre déclenchée par Moukhtar à Koufa, Hissan Ibn Fahid Ibn Bakir al-‘Absi, des Bani Mouti’, se dirigea vers Ibrahim Ibn al-Ashtar. Le commandant des Bani Ashtar était Khouzaymah Ibn Nasr al-‘Absi et l’affrontement des deux armées qui suivit tourna à l’avantage des Bani Mouti’.

  

Les Bani Ashtar s’enfuirent excepté Hissan Ibn Fahid qui resta en arrière pour protéger le retrait de sa troupe jusqu’à ce qu’il fut encerclé.

  

Son oncle, Khouzaymah Ibn Nasr, descendit de son cheval s’approcha de lui pour le protéger et lui offrit la sécurité. Lorsqu’Ibrahim Ibn al-Ashtar arriva, il lui dit :

  

- « Celui-ci est le fils de mon oncle maternel. Je lui ai accordé la sécurité ! »

  

- « Tu as bien fait », lui fut-il répondu.

  

Khouzaymah Ibn Nasr donna un cheval à Hissan et lui dit :

  

- « Rejoint les tiens ! »

  

L’état des Omeyyades fut un état de pur tribalisme. C’est pour cela que nous avons dû présenter la généalogie des Arabes en début de livre sans quoi, l’histoire des Omeyyades aurait été incompréhensible sans connaitre l’origine des tribus et des gens. Et toutes ces tribus ou des membres de ces tribus ont joué un rôle important dans l’histoire des Omeyyades.

  

Toujours, lors d’une des batailles, suite à la révolte de Moukhtar, lorsqu’un groupe de ses combattants tomba entre les mains de Shabath Ibn Rib’i ar-Riyahi at-Tamimi, qui demanda à l’un d’entre eux :

  

- « Qui es-tu ? »

  

- « Je suis Khoulayd, le servant de Hassan Ibn Mahdoudj ad-Douhairi ».

  

Shabath ordonna de le tuer. Mais lorsqu’on lui présenta Si’r Ibn Abi Si’r al-Hanafi et qu’il apprit qu’il était des Bani Hanifah, il le fit relâcher.

  

Lorsqu’un autre servant, qui assista à la réplique de Khoulayd, lui fut présenté, Shabath lui demanda, qui il était :

  

- « Je suis des Bani Ziyad akh-Khassafah et les Ziyad Ibn Khassafah des Bani Taymim Tha’labah Ibn Wahil ».

  

- « Tu m’as fait rappeler l’honorable ancêtre », lui répondit Shabath, et il le libéra.

  

Les Arabes ne tuaient jamais les servants et les esclaves lors des batailles comme nous avons déjà précédemment donné l’exemple lors de la bataille de Karbala ou al-Houssayn (qu’Allah soit satisfait de lui et de son père) trouva la mort.

  

‘Omar Ibn Sa’d Ibn Abi Waqqas ne tua pas non plus ‘Ouqbah Ibn Sim’an qui était avec al-Houssayn.

  

Mais là, Shabath Ibn Rib’i tua un servant car Moukhtar avait engagé dans son armée des servants et des esclaves et leur avait ordonné de combattre comme les autres. Les servants et les esclaves travaillaient pour les Arabes et c’est pour cela qu’ils n’étaient pas tués. Mais ceux-là avaient pris les armes contre eux, donc, ils méritaient la mort car ils étaient considérés comme des combattants aux même titres que les autres.

  

La bataille de Djabanat as-Sabi’

  

La guerre civile (ahliyah) menée par Moukhtar Ibn Abi ‘Oubayd ath-Thaqafi à Koufa finit en victoire pour lui. Il envoya à Ibn Mouti’ mille dirhams et lui demanda de quitter Koufa.

  

Lorsque Ibn Mouti’ vit la victoire de Moukhtar, il eut peur et quitta la ville. Il ne retourna pas à La Mecque mais alla à Basra par crainte de ‘AbdAllah Ibn Zoubayr.

  

Les gens de Koufa portèrent allégeance à Moukhtar par colère pour avoir engagé les esclaves et les servants dans son armée et pour avoir partagé avec eux les biens récupérés. Une chose jamais faite auparavant et qu’ils considéraient comme une erreur majeure.

  

Une nouvelle guerre civile eut lieu dans les faubourgs de Koufa et une nouvelle bataille s’ensuivit : la bataille de Djabanat as-Sabi’.

  

Djabanat est une terre déserte (sahrawiyah) et le désert comme vous le savez est très proche de Koufa. Sabi’ est de la tribu de Hashid. Il est Hashid Ibn Joushan Ibn Houbouran Ibn Nawfal Ibn Hamdan. Sabi’ est une des branches de la tribu Hamdan et Sabi’ Ibn Sab’ Ibn Sa’b Ibn Mou’awiyah Ibn Kathir Ibn Malik Ibn Joushan Ibn Hashid.

  

Moukhtar Ibn Abi ‘Oubayd ath-Thaqafi assit son pouvoir et poursuivit les assassins d’al-Houssayn (qu’Allah soit satisfait de lui). Son entreprise réussit et ses partisans tuèrent l’infâme Shamir Ibn Dzoul Jousham, qui était un redoutable combattant, qui avait été le principal responsable de la mort d’al-Houssayn (qu’Allah soit satisfait de lui) et qui avait incité les gens à son assassinat à Karbala.

  

Ils tuèrent aussi Khawli Ibn Yazid Asbahi, celui qui avait transporté la tête d’al-Houssayn (qu’Allah soit satisfait de lui) tranchée par Sinan Ibn Abi ‘Amr Ibn Anas al-Qat’ami.

  

Moukhtar ordonna que Khawli Ibn Yazid Asbahi soit tué et brûlé jusqu’à ce qu’il devienne de la poussière.

  

‘Omar Ibn Sa’d Ibn Abi Waqqas, le commandant de l’armée de ‘Oubaydillah Ibn Ziyad le jour de Taff à Karbala fut aussi tué. Sa tête fut tranchée par Abou ‘Amrah Kayssan, le servant de Qouraynah, le chef de la garde personnelle de Moukhtar.

  

Les nobles de Koufa allèrent à Basra rencontrer Mous’ab Ibn Zoubayr pour lui raconter les exploits de Moukhtar « le menteur » (al-kadab).

  

Wadi al-Koura

  

En Syrie, Le cinquième calife omeyyade, ‘Abdel Malik Ibn Marwan Ibn Hakam envoya une armée à Wadi al-Koura pour combattre ‘AbdAllah Ibn Zoubayr (qu’Allah soit satisfait de lui) sous le commandement de Harith Ibn Hakam Ibn Abi al-‘As Ibn Oumayyah.

  

Lorsque Moukhtar fut informé du départ de l’armée, il envoya une lettre à ‘AbdAllah Ibn Zoubayr qu’il détestait. Il l’informa du départ de l’armée de Syrie pour le combattre et lui proposa de lui envoyer son armée.

  

‘AbdAllah Ibn Zoubayr accepta son offre et lui demanda intelligemment d’envoyer son armée directement à Wadi al-Koura intercepter l’armée de Syrie et pour éviter que cette armée ne se retourne contre lui.

  

Moukhtar, attendait l’arrivée de l’armée de Syrie par l’ouest. Il envoya un corps de troupe de trois-mille hommes commandée par Shourahbil Ibn Warss Hamdani et lui ordonna de marcher sur Médine et non pas à Wadi al-Koura comme le lui avait demandé Ibn Zoubayr.

  

Moukhtar « le menteur » espérait le tromper mais ‘AbdAllah Ibn Zoubayr était d’une méfiance extrême à son égard. Ibn Zoubayr envoya mille hommes commandé par Ibn ‘Abbas Ibn Sahl et lui ordonna que s’il avait le moindre doute ou sentait la moindre traitrise de l’armée de Moukhtar de combattre aussitôt Shourahbil. Et c’est ce qui arriva.

  

Lorsqu’Ibn ‘Abbas Ibn Sahl rencontra Shourahbil Ibn Warss et connut ses intentions, il le tua ainsi qu’un très grand nombre de ses soldats, lors d’une terrible bataille.

  

La mort de ‘Oubaydillah Ibn Ziyad

  

A Koufa, lorsque Moukhtar eut finit avec la bataille de Djabanat as-Sabi’, il envoya Ibrahim Ibn Ashtar an-Nakha’i pour combattre l’armée de ‘Oubaydillah Ibn Ziyad et ceux qui étaient avec lui de Syrie.

  

Au mois de Dzoul Hijjah de l’année 66 de l’Hégire (685), les deux armées se rencontrèrent près de Khazar près de Mossoul. Il s’ensuivit une lourde et mortelle bataille ou Ibrahim fut durement éprouvé mais il combattit férocement comme il en avait l’habitude.

  

‘Oubaydillah Ibn Ziyad fut tué au cours de la bataille ainsi que Houssayn Ibn Noumayr as-Sakouni, commandant de l’aile droite de l’armée de Syrie. Le commandant de la cavalerie de l’armée de Syrie, Shourahbil Ibn Dzil Kala’ fut aussi tué ainsi qu’un nombre très important d’hommes de l’armée de Syrie.

  

Les batailles de Madar et de Harourah contre Moukhtar « le Menteur »

  

Au début de l’année 67 de l’Hégire (686), ‘Abdallah Ibn Zoubayr (qu’Allah soit satisfait de lui) écarta du poste de gouverneur à Basra Kouba’, Harith Ibn ‘Abdillah Ibn Abi Rabi’ah al-Makzoumi, et le remplaça par son frère Mous’ab Ibn Zoubayr.

  

Lorsqu’il arriva dans la ville, les nobles qui avaient souffert des actes de Moukhtar, lors de la bataille de Djabanat as-Sabi’, lui demandèrent de le combattre.

  

Mous’ab Ibn Zoubayr répondit à leur demande et prépara une grande armée composée des nobles et des chefs de la ville dont Ahnaf Ibn Qays at-Tamimi, Malik Ibn Misma’ al-Bakri, al-Mouhallab Ibn Abi Soufrah al-Azdi et leur chef Muhammad Ibn Ashraf al-Kindi.

  

Mous’ab Ibn Zoubayr était lui-même, un commandant de troupe et un valeureux combattant renommé.

  

A Madar, un endroit se trouvant à quatre jours de marche à l’est de Basra sur la rive du fleuve du Tigre eut lieu la bataille entre les deux armées : L’armée de Moukhtar le Menteur commandée par Ahmar Ibn Shoumayr al-Ouhmoussi al-Bajali et celle de Basra commandée par Mous’ab Ibn Zoubayr.

  

Et comme cela est commun, le combat entre les Musulmans arabes fut redoutable, terrifiant et sanglant. L’armée de Moukhtar fut anéantie et Ahmar Ibn Shoumayr fut tué. L’armée victorieuse de Mous’ab poursuivit sa route et marcha sur Koufa et Moukhtar.

  

A Harourah eut lieu la deuxième bataille et la suite de ce qui avait commencé à Madar. Et le reste de l’armée de Moukhtar fut aussi défait. Muhammad Ibn Ashraf al-Kindi, un des plus nobles arabes de Koufa de son temps, fut tué.

  

L’armée de Mous’ab marcha alors sur la forteresse de Moukhtar ou il s’était fortifié en compagnie de huit-mille de ses partisans et mit le siège. Le siège fut si intense que Moukhtar n’eut d’autre choix que de sortir combattre.

  

Il demanda la sécurité mais cela lui fut refusé tant qu’il ne se soumettrait pas au jugement de Mous’ab mais il refusa, sachant qu’il serait tué.

  

Alors, il sortit avec uniquement dix-neuf de ses partisans et combattit jusqu’à ce qu’il fut tué. Mous’ab ordonna que sa main soit tranchée et clouée près de la mosquée de Koufa.

  

Moukhtar le Menteur Abi ‘Oubayd ath-Thaqafi trouva la mort au mois de Ramadan de l’année 67 de l’Hégire (686) alors qu’il était âgé de 67 ans.

  

Voici ce qu’a rapporté de lui l’Imam Tabari dans son livre d’histoire : « Lorsque le siège de Moukhtar se fit plus intense, il dit à Mous’ab :

  

- « Nous sommes prêts à sortir si vous nous assurez notre sécurité ». On lui répondit :

  

- « Non, aucune sécurité de notre part. Sors et soumet toi à notre jugement ! »

  

Mais il refusa puis sortit de la forteresse pour combattre jusqu’à être tué et pour ne pas être capturer vivant.

  

Moukhtar dit à son député Sa’id Ibn Malik al-Ash’ari :

  

- « Je suis un homme des Arabes. J’ai vu Ibn Zoubayr mettre la main sur le Hijaz, Najd Ibn ‘Amir al-Hanafi sur le Yémen et Marwan sur la Syrie. Je ne suis pas n’importe qui parmi les Arabes, c’est pourquoi j’ai pris ce pays. J’étais comme l’un d’entre eux sauf que j’ai demandé que les gens de la Maison du Prophète (Saluts et Bénédictions d’Allah sur lui) soient vengés parce que les Arabes ne l’ont pas fait. J’ai tué ceux qui ont participé à leurs assassinats et suis resté vivant jusqu’à ce jour. Combats comme tu peux si tu ne le fais pour aucune intention. »

  

Il est vrai que Moukhtar le Menteur a fait beaucoup et trop d’erreurs…

  

Mous’ab Ibn Zoubayr renommé au poste de gouverneur d’Iraq

  

Après sa victoire sur Moukhtar le Menteur, Mous’ab Ibn Zoubayr fit sept-mille prisonniers.

  

Boujayr Ibn ‘Abdillah al-Mousli, un des hommes de Moukhtar, dit à Mous’ab Ibn Zoubayr :

  

- « Quiconque pardonne verra Allah lui pardonner et lui rajouter de la puissance et quiconque punit n’est pas à l’abri du châtiment, ainsi que beaucoup d’autres paroles ».

  

Mous’ab était sur le point de leur pardonner grâce aux propos de cet homme mais ‘AbderRahmane Ibn Muhammad Ibn Ash’at Ibn Qays al-Kindi et les nobles s’opposèrent à lui et lui dirent :

  

- « Veux-tu les libérer, après tout ce qu’ils ont fait de mal ? Choisit entre eux ou nous ! »

  

Muhammad Ibn ‘AbderRahmane Ibn Sa’id Ibn Qays al-Hamdani lui dit aussi :

  

- « Ils ont tué mon père avec d’autres membres de notre famille, ainsi que beaucoup de gens de Koufa et tu veux les laisser libres ? Choisit entre eux ou nous ! »

  

Mous’ab ordonna alors de tous les tuer. Sept-mille personnes qui ont choisi de ne pas le combattre, de se rendre et se soumettre à son jugement !

  

Sept-mille personnes tuées à cause d’une sédition, c’est un prix très lourd ! Mais si l’on compte tous les gens qui ont été tué lors des batailles engendrées par l’assassinat de ‘Uthman Ibn ‘Affan, Dzoul Nourayn (qu’Allah soit satisfait de lui), le prix est encore bien plus lourd. La porte de la sédition a été ouverte et c’est exactement ce qui est arrivé comme l’avait dit le Messager d’Allah (Saluts et Bénédictions d’Allah sur lui).

  

Lorsque Mous’ab Ibn Zoubayr mit fin à la sédition de Moukhtar le Menteur, il nomma al-Mouhallab Ibn Abi Soufrah gouverneur de Mossoul, d’al-Jazirah, de l’Azerbaïdjan et de l’Arménie tandis que lui resta à Koufa.

  

Puis il envoya un messager à Ibrahim Ibn al-Ashtar an-Nakha’i, le redoutable chef combattant, pour le confirmer à son poste. Mais ‘Abdel Malik Ibn Marwan lui envoya aussi un messager pour lui dire la même chose pour les mêmes raisons sachant qu’il était un excellent cavalier et sa tribu puissante.

  

Ibrahim Ibn al-Ashtar, qui avait été un des commandant de Moukhtar, préféra rejoindre les rangs de Mous’ab parce qu’il craignit d’aller en Syrie pour avoir combattu et écrasé l’armée de ‘Abdel Malik commandée par ‘Oubaydillah Ibn Ziyad qu’il avait tué.

  

Après cela, ‘AbdAllah Ibn Zoubayr (qu’Allah soit satisfait de lui) écarta son frère Mous’ab de Basra et le remplaça par son fils Hamzah Ibn ‘Abdillah Ibn Zoubayr, qui n’avait ni la force et ni la mentalité de Mous’ab et que les gens de Koufa n’aimèrent pas.

  

Ahnaf Ibn Qays écrivit à ‘AbdAllah Ibn Zoubayr et lui demanda de limoger Hamzah et de reconduire Mous’ab.

  

‘AbdAllah Ibn Zoubayr en fin politicien, remit Mous’ab à son poste de gouverneur comme le lui avait demandé Ahnaf. Mous’ab resta à peu près une année à Koufa avant que son frère le désiste une nouvelle fois de Basra et le remplace par son fils Hamzah.

  

Mous’ab retourna à La Mecque et après s’être entretenu avec son frère, ‘AbdAllah, le renomma émir de Basra en l’an 68 de l’Hégire (687).

  

Le retour des khawarije

  

En l’an 68 de l’Hégire (687), Mous’ab Ibn Zoubayr qui était émir de l’Iraq stationné à Basra, nomma Harith Ibn ‘Abdillah Ibn Abi Rabi’ah émir de Koufa et ‘Omar Ibn ‘Abdillah Ibn Ma’mar émir de Perse.

  

Les khawarije qui avaient fuient à Kirmân et Ispahan, après leur défaite en l’an 66 de l’Hégire (685) contre al-Mouhallab dans l’Ahwaz et commandés par Zoubayr Ibn Mahouz at-Tamimi attaquèrent ‘Omar Ibn ‘Abdillah. Néanmoins Ibn Ma’mar réussit à les battre et à les expulser.

  

Les khawarije se réfugièrent de nouveau à Ispahan et à Kirmân, ou ils organisèrent leurs forces pour capturer Koufa et marchèrent sur l’Ahwaz.

  

Ibn Ma’mar informé de leurs mouvements les poursuivit avec son armée tandis que Mous’ab prévenu de leur arrivée se prépara en conséquence.

  

Al-Mouhallab Ibn Abi Soufrah al-Azdi

  

L’Ahwaz connut alors l’outrage et la terreur des khawarije, ces criminels qui seront les chiens de l’enfer. Ils massacrèrent les Musulmans de Mada'in, femmes, hommes, enfants et vieillards et éventrèrent les femmes enceintes. Puis, ils marchèrent sur les faubourgs d’Ispahan ou eut lieu une féroce bataille entre eux et les Musulmans commandé par ‘Atab Ibn Warqah Ibn Harith Ibn ‘Amr at-Tamimi.

  

Les khawarije furent battu et leur chef Zoubayr Ibn Mahouz at-Tamimi fut tué et aussitôt remplacé par Qatari Ibn al-Fouja’ah at-Tamimi. Mais cela ne les empêcha pas de poursuivre leurs agressions contre les Musulmans qui souffrirent beaucoup de leurs maux.

  

Mous’ab sut alors qu’il devait les arrêter coute que coute et leur opposer un redoutable chef combattant. Il ne trouva personne de mieux que le chef renommé al-Mouhallab Ibn Abi Soufrah al-Azdi qui était l’émir de Mossoul et d’al-Jazirah.

  

Mous’ab lui ordonna donc de faire face aux khawarije et pendant huit mois, Ibn Abi Soufrah les combattit farouchement et particulièrement à Soulaf ou eut lieu une grande bataille.

  

Afin que nous voyons la différence entre les gens de l’Iraq et les gens de Syrie, à propos de la richesse, de l’obéissance aux gouverneurs, lorsque Mous’ab voulut s’opposer à ‘Abdel Malik Ibn Marwan, Qays Ibn al-Aytham Ibn Qays Ibn Salt Ibn Habib as-Soulami qui était de Basra et un des plus fervent partisans de Mous’ab Ibn Zoubayr leur dit :

  

- « Malheur à vous ! Ne cherchez pas à attirer l’armée de Syrie contre vous ! Par Allah, j’ai vu les gens de Syrie, heureux aux portes du calife, s’ils les envoyaient contre vous ou leur demandaient n’importe quoi ! Je nous ai vus au combat sur des ânes tandis qu’un seul d’entre est sur un cheval et les autres suivent à pieds ! »

  

Pourquoi l’Iraq était-elle donc plus riche que la Syrie ?

  

Lorsque les Musulmans capturèrent l’empire perse, ils le firent en une seule fois et ils héritèrent de toutes ses richesses, parce que la Perse était un grand et riche pays. Puis ensuite, les Musulmans capturèrent tous ses états vassaux

  

Ainsi celui qui contrôlait l’Iraq avait des revenus immenses qui venaient de l’empire perse.

  

Tandis que lorsque les Musulmans battirent les Byzantins, ils les expulsèrent uniquement de Syrie et d’Egypte. Quant à l’empire byzantin, il était toujours présent à Constantinople et ne tomba que huit siècles plus tard en l’an 857 de l’Hégire (1452), sous le commandement du sultan Muhammad II (thani), connu après cela sous le nom de Muhammad al-Fatih (qu'Allah lui fasse miséricorde).

  

La rébellion de ‘Amr Ibn Sa’id Ibn al-‘As

  

Depuis la mort de Yazid Ibn Mou’awiyah, au mois de Rabi’ Awwal de l’année 64 de l’Hégire (683), les révoltes se succédèrent partout et les Musulmans entrèrent en conflit pour le pouvoir (moulk) et s’entretuèrent entre eux.

  

En l’an 69 de l’Hégire (688), ‘Abdel Malik quitta Damas et marcha vers Qalqissiyah pour combattre Zoufar Ibn Harith al-Kilabi et laissa ‘AbderRahmane Ibn Oumm al-Hakam ath-Thaqafi pour le remplacer à Damas. ‘AbderRahmane Ibn Oumm Hakam est ‘AbderRahmane Ibn ‘Abdillah Ibn ‘Uthman Ibn ‘Abdillah Ibn Rabi’ah ath-Thaqafi et sa mère est Oumm Hakam Ibn Abi Soufyan, la sœur de Mou’awiyah (qu’Allah soit satisfait de lui).

  

‘Abdel Malik sortit en compagnie de ‘Amr Ibn Sa’id Ibn al-‘As Ibn Sa’id Ibn al-‘As Ibn Oumayyah, surnommé « al-Ashdaq », le fils de son oncle. Sa mère est la mère d’enfants Bint Hakam Ibn Abi al-‘As.

  

Alors qu’ils étaient marche avec leurs armées, ‘Amr Ibn Sa’id dit à ‘Abdel Malik :

  

- « Ton père m’avait promis de me nommer après lui pour me tenir à ses côtés et le servir. Nomme-moi calife après toi ». Mais ‘Abdel Malik ne lui répondit pas et resta silencieux.

  

La nuit venue, ‘Amr Ibn Sa’id quitta secrètement le camp et retourna à Damas sans que personne ne remarque son absence. Il partit accompagné de Houmayb Ibn Hourays Ibn Bahdal al-Kalbi et Zouhayr Ibn Abrad al-Kalbi

  

Ils réussirent à destituer ‘AbderRahmane Ibn Oumm Hakam, le député de ‘Abdel Malik et ‘Amr Ibn Sa’id se fortifia à Damas.

  

Lorsque le matin arriva, ‘Abdel Malik s’aperçu de l’absence de ‘Amr et fit aussi demi-tour et rentra aussitôt à Damas.

  

Une bataille s’ensuivit entre lui et ‘Amr qui sortit la cavalerie pour le combattre. Les chefs des deux armées qui se faisant face étaient issus de la tribu des Kalb Ibn ‘Abarah connut pour leur endurance au combat.

  

Soufyan Ibn Abrad al-Kalbi, le célèbre chef dont nous parlerons plus tard combattit aux cotés de ‘Abdel Malik Ibn Marwan avec Hassan Ibn Malik Ibn Bahdal al-Kalbi. La bataille dura si longtemps que les femmes des Kalbi sortirent voir leurs maris Soufyan Ibn Abrad et Hassan Ibn Malik et leur dirent :

  

- « Pourquoi vous combattez-vous entre vous pour cet homme des Qouraysh ? »

  

Ces paroles les firent réfléchir. Ils pensèrent à arrêter le combat et effectivement peu après, les deux armées conclurent un pacte de paix entre eux mais ce genre de pacte n’était pas fait pour durer.

  

La mort de ‘Amr Ibn Sa’i.d Ibn al-‘As

  

‘Abdel Malik Ibn Marwan connaissait dorénavant l’intention de ‘Amr de s’emparer du califat et du danger qu’il représentait. Il chercha un moyen de se débarrasser de lui et un jour, il lui demanda de lui rendre visite.

  

Ses partisans le mirent en garde de ne pas aller mais il refusa de les écouter. ‘Amr lui rendit donc visite en compagnie de cent servants.

  

‘Abdel Malik Ibn Marwan s’était préparé à le recevoir et lorsque ‘Amr arriva au palais, les gardes le laissèrent entrer mais pas ses serviteurs, à l’exception d’un seul, puis, ils fermèrent les portes.

  

Lorsque ‘Amr Ibn Sa’id, al-Ashdaq, pressentit le danger qui le guettait, il s’empressa de cajoler et de réconforter le calife sur ses intentions mais ‘Abdel Malik ordonna à ses gardes de le tuer.

  

Durant ces tragiques évènements ‘Abdel ‘Aziz Ibn Marwan, le fils de ‘Omar Ibn ‘Abdel ‘Aziz, le frère du calife ‘Abdel Malik joua un rôle important et décisif en poussant son frère au poste de calife, qui voulait punir les fils de son oncle, Yahya Ibn Sa’id Ibn ‘As et ‘Ambassah Ibn Sa’id.

  

‘Abdel ‘Aziz Ibn Marwan lui dit :

  

- « Je te rappelle, ô émir des croyants, de prendre soin des Bani Oumayyah et de ne pas les tuer. Si bien que ‘Abdel Malik Ibn Marwan ne les tua pas mais les emprisonna avant de les envoyer chez Mous’ab Ibn Zoubayr, ou ils restèrent.

  

‘Amr Ibn Sa’id Ibn al-‘As Ibn Sa’id Ibn al-‘As al-Oumayyah Ibn ‘Abd ash-Shams est un des Banou Oumayyah et les plus proches de ‘Abdel Malik Ibn Marwan qui est, ‘Abdel Malik Ibn Marwan Ibn Hakam Ibn Abi al-‘As Ibn Oumayyah, al-‘As et Abou al-‘As sont des frères. Et pourtant, ils s’entretuèrent pour le pouvoir.

  

Que dire alors des fils de ses oncles les Bani Hashim Ibn ‘Abdel Manaf et Banou Oumayyah Ibn ‘Abd ash-Shams Ibn ‘Abdel Manaf ! Les Bani ‘Abbas Ibn ‘Abdel Moutalib Ibn Hashim et les Bani ‘Ali Ibn Abi Talib Ibn ‘Abdel Moutalib Ibn Hashim s’entretuèrent aussi lors du règne des Abbassides. Le frère tuant son frère, le fils tuant son père et le père tuant son fils. Il n’y a de force et de puissance qu’en Allah !

  

Il y a beaucoup d’exemples similaires de fratricides, d’infanticides et de parricides que ce soit dans l’histoire des Omeyyades, des Abbassides ou des Ottomans et même chez les non-musulmans.

  

Ces troubles atteignirent un tel niveau, qu’en l’an 70 de l’Hégire (689) et pour la première fois, les Byzantins sous le règne de Justinien II attaquèrent les frontières de la Syrie et poussèrent ‘Abdel Malik Ibn Marwan à leur faire des concessions et à leur donner 1000 dinars chaque vendredi. ‘Abdel Malik Ibn Marwan accepta pour éviter qu’ils causent du tort aux Musulmans.

The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family).

 

It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.

 

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in many societies that use it.

 

DESCRIPTION

PLANT

Cocos nucifera is a large palm, growing up to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 – 20 years to reach peak production.

 

FRUIT

Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.

 

A full-sized coconut weighs about 1.44 kg. It takes around 6,000 full-grown coconuts to produce a tonne of copra.

 

ROOTS

Unlike some other plants, the palm tree has neither a tap root nor root hairs, but has a fibrous root system.

 

The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.

 

Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.

 

Roots are usually less than about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.

Inflorescence

 

The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating.

 

ETYMOLOGY

One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam and Tamil name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.

 

Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Tamil/Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".

 

The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.

 

The specific name nucifera is Latin for "nut-bearing".

Origin, domestication, and dispersal

 

ORIGIN

The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.

 

DOMESTICATION

Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population.

 

Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.

 

Variants of C. nucifera are also categorized as Tall (var. typica) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.

 

DISPERSAL

It is often stated that coconuts can travel 110 days, or 4,800 km, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: "The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.

 

Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatellite loci, researchers found two genetically distinct subpopulations of coconut - one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.

 

DISTRIBUTION

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.

  

NATURAL HABITAT

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm of rainfall per year, but is consistently warm and humid.

 

Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C, and survival as long as winter temperatures are above 4–12 °C; they will survive brief drops to 0 °C. Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C. They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.

 

The conditions required for coconut trees to grow without any care are:

 

- Mean daily temperature above 12–13 °C every day of the year

- Mean annual rainfall above 1000 mm

- No or very little overhead canopy, since even small trees require direct sun

 

The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.

 

DISEASES

Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, the Maypan, has been bred for resistance to this disease.

 

PESTS

The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.

 

Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.

 

The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor-intensive.

 

In Kerala (India), the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009 yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach (CAGA) to combat coconut mites.

 

PRODUCTION AND CULTIVATION

Coconut palms are grown in more than 90 countries of the world, with a total production of 62 million tonnes per year (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines and India accounting collectively for 73% of the world total (table).

 

CULTIVATION

Coconut trees are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.

 

The extent of cultivation in the tropics is threatening a number of habitats, such as mangroves; an example of such damage to an ecoregion is in the Petenes mangroves of the Yucatán.

 

HARVESTING

In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.

 

INDIA

Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. As per 2013-14 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 92% of the total production in the country: Tamil Nadu (31.93%), Kerala (27.54%), Karnataka (23.26%), and Andhra Pradesh (8.43%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.

 

Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other. In Tamil Nadu, a coconut tree is called as "Thennai maram" and tender coconut is called as "Ilaneer" in the native language.

 

MALDIVES

The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.

 

MIDDLE EAST

The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.

 

The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.

 

The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[52] The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.

 

Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.

 

SRI LANKA

An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat.

 

UNITED STATES

In the United States coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.

 

In Florida, Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in Tampa and Clearwater, as well as around Cape Canaveral and Daytona Beach on the east coast. They reach fruiting maturity, but can be damaged or killed by the occasional winter freezes in these areas. In South Texas they may also be grown in favoured microclimates around the Rio Grande Valley near Brownsville, and as far north as Corpus Christi , however more severe cold snaps keep them from producing viable fruit.

 

AUSTRALIA

Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.

 

BERMUDA

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.

 

In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.

 

Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.

 

EUROPE

As a tropical plant, coconut is not native to Europe, but grows in tropical territories of European countries, such as Martinique and Guadeloupe (France), the Canary Islands (Spain) and Madeira (Portugal).

 

COOLER CLIMATES

In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C and need a daily temperature above 22 °C to produce fruit.

 

USES

The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".

 

COOKING

The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Some countries in South East Asia use special coconut mutant called Kopyor (in Indonesian) or macapuno (in Philippines) as a dessert drinks.

 

NUTRITION

Per 100 gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat) and carbohydrates (24 grams) (table). Micronutrients in significant content include the dietary minerals, manganese, iron, phosphorus and zinc (table).

 

COCONUT WATER

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

 

Per 100 gram (100 ml) serving, coconut water contains 19 calories and no significant content of essential nutrients.

 

COCONUT MILK

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.

 

A protein-rich powder can be processed from coconut milk following centrifugation, separation and spray drying.

 

COCONUT OIL

Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.

 

TODDY AND NECTAR

The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".

 

The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters of toddy per year, while a 40-year-old tree may yield around 400 liters.

 

HEART OF PALM AND COCONUT SPROUT

Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.

 

INDONESIA

Coconut is an indispensable ingredient in Indonesian cooking. Coconut meat, coconut milk and coconut water are often used in main courses, desserts and soups throughout the archipelago. In the island of Sumatra, the famous Rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, "Soto Babat" or beef tripe soup also uses coconut milk. In the island of Java, the sweet and savoury "Tempe Bacem" is made by cooking tempeh with coconut water, coconut sugar and other spices until thickened. "Klapertart" is the famous Dutch-influenced dessert from Manado, North Celebes, that uses young coconut meat and coconut milk. In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.

 

PHILIPPINES

The Philippines is the world's largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko and coconut pie. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product - nata de coco (coconut gel).

 

VIETNAM

In Vietnam, coconut is grown abundantly across Central and Southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè and curry (cà ri).

 

INDIA

In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.
