Coconut

The Coconut Palm (Cocos nucifera) is a member of the Family Arecaceae (palm family). It is the only species in the genus Cocos, and is a large palm, growing to 30 m tall, with pinnate leaves 4-6 m long, pinnae 60-90 cm long; old leaves break away cleanly leaving the trunk smooth. The term coconut refers to the seed of the coconut palm. An alternate spelling is cocoanut. The coconut palm is grown throughout the tropical world, for decoration as well as for its many culinary and non-culinary uses; virtually every part of the coconut palm has some human uses.

The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. The fruit is light and buoyant and presumably spread significant distances by marine currents. Fruits collected from the sea as far north as Norway have been found to be viable (and subsequently germinated under the right conditions). 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 the South Pacific.

The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (150 cm to 250 cm 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, like the Mediterranean, even where temperatures are high enough. Coconut trees are very 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. Plant densities in Vanuatu for copra production are generally 9 meter, allowing a tree density of 100–160 trees per hectare.

The main coconut producing area in the Middle East is the Dhofar region of Oman. Particular the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea.The large coconut grooves of Dhofar are already mentioned by the medieval Moroccan traveller Ibn Battuta in his writings known as Al Rihla.This is possible due to an annual rainy season known locally as Khareef.Coconut are also increasingly grown for decorative purposes along the coasts of 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 spreading of pests that can spread to other native palm trees such as the date palm.
