Tamarind (
Tamarindus indica) is a leguminous tree in the family Fabaceae indigenous to tropical
Africa. The genus Tamarindus is a monotypic taxon, having only a single species.
The tamarind tree produces edible, pod-like fruit which is used extensively in cuisines around the world. Other uses include traditional medicine and metal polish.
The wood can be used in carpentry. Because of the tamarind's many uses, cultivation has spread around the world in tropical and subtropical zones.
Origin :
Tamarindus indica is probably indigenous to tropical Africa, but has been cultivated for so long on the
Indian subcontinent that it is sometimes also reported to be indigenous there. It grows wild in Africa in locales as diverse as
Sudan,
Cameroon,
Nigeria and
Tanzania. In
Arabia, it is found growing wild in
Oman, especially
Dhofar, where it grows on the sea-facing slopes of mountains. It reached
South Asia likely through human transportation and cultivation several thousand years prior to the
Common Era. It is widely distributed throughout the tropical belt, from Africa to South Asia,
Northern Australia, and throughout
Oceania,
Southeast Asia,
Taiwan and China.
In the 16th century, it was heavily introduced to
Mexico, and to a lesser degree to
South America, by
Spanish and Portuguese colonists, to the degree that it became a staple ingredient in the region's cuisine.
Today,
India is the largest producer of tamarind.
The consumption of tamarind is widespread due to its central role in the cuisines of the Indian subcontinent,
South East Asia and
America, particularly in Mexico.
Description:
The tamarind is a long-lived, medium-growth, bushy tree, which attains a maximum crown height of 12 to 18 metres (39 to 59 ft). The crown has an irregular, vase-shaped outline of dense foliage. The tree grows well in full sun in clay, loam, sandy, and acidic soil types, with a high resistance to drought and aerosol salt (wind-borne salt as found in coastal areas).
The evergreen leaves are alternately arranged and pinnately compound. The leaflets are bright green, elliptical ovular, pinnately veined, and less than
5 cm (
2.0 in) in length. The branches droop from a single, central trunk as the tree matures and is often pruned in agriculture to optimize tree density and ease of fruit harvest. At night, the leaflets close up.
The tamarind does flower, though inconspicuously, with red and yellow elongated flowers.
Flowers are 2.5 cm wide (one inch), five-petalled, borne in small racemes, and yellow with orange or red streaks.
Buds are pink as the four sepals are pink and are lost when the flower blooms.
The fruit is an indehiscent legume, sometimes called a pod, 12 to 15 cm (4.7 to 5.9 in) in length, with a hard, brown shell.
The fruit has a fleshy, juicy, acidulous pulp. It is mature when the flesh is coloured brown or reddish-brown. The tamarinds of
Asia have longer pods containing six to 12 seeds, whereas African and
West Indian varieties have short pods containing one to six seeds. The seeds are somewhat flattened, and glossy brown.
As a tropical species, it is frost sensitive. The pinnate leaves with opposite leaflets give a billowing effect in the wind. Tamarind timber consists of hard, dark red heartwood and softer, yellowish sapwood.
It is harvested by pulling the pod from its stalk. A mature tree may be capable of producing up to
175 kg (386 lb) of fruit per year.
Veneer grafting, shield (T or inverted T) budding, and air layering may be used to propagate desirable selections. Such trees will usually fruit within three to four years if provided optimum growing conditions.
Etymology :
The name derives from
Arabic: تمر هندي, romanized tamar hindi, "
Indian date". Several early medieval herbalists and physicians wrote tamar indi, medieval
Latin use was tamarindus, and
Marco Polo wrote of tamarandi.
In
Colombia, Cuba,
Dominican Republic, Mexico,
Puerto Rico,
Venezuela and throughout the Lusosphere, it is called tamarindo
. In the Caribbean, tamarind is sometimes called tamón. Tamarind (Tamarindus indica) is sometimes confused with "
Manila tamarind" (
Pithecellobium dulce). While in the same taxonomic family Fabaceae, Manila tamarind is a different plant native to Mexico and known locally as guamúchil.
Cultivation:
Seeds can be scarified or briefly boiled to enhance germination. They retain germination capability after several months if kept dry.
The tamarind has also long been naturalized in
Indonesia,
Malaysia,
Sri Lanka,
Philippines, and the
Pacific Islands.
Thailand has the largest plantations of the
ASEAN nations, followed by Indonesia,
Myanmar, and the Philippines. The pulp is marketed in northern
Malaya. It is cultivated all over India, especially in the
South Indian states of
Maharashtra Karnataka,
Andhra Pradesh and
Tamil Nadu. Extensive tamarind orchards in India produce 275,
500 tons (
250,000 MT) annually.
