2.2 Income generation • The yield of jackfruit trees may vary year to year depending on management and climatic factors. However, it bears fruits every year and thus provides a source of income. Its average yield is approximately 10 t/ha. • Tender fruits can be sold as a vegetable, bringing early income before peak fruiting season. • Ripe fruits can also be sold either fresh or processed for an income. • Additional income may be earned by intercropping the open space between trees until the tree canopy closes by growing short duration pulses, spices and vegetables, if water availability is not limited. 2.3 Cultural • Popular fruit in tropical and subtropical countries, and most Asian cultures value jackfruit primarily as a food. • In Hindu communities, jackfruit leaves are often used in temple worship. • Buddhist priests use the fruit to colour their robes. • Wood yields yellow dye when wood chips are boiled. 2.4 Medicinal value Parts of jackfruit trees are used in traditional medicine throughout tropical Asia. However, no major clinical evidence is available to support these uses and a medical practitioner should be consulted. • Roots o An extract of roots is used in treating skin diseases, asthma and diarrhoea. • Leaves o An extract from leaves and latex treats asthma, prevents ringworm infestation, and heals cracking of the feet. o An infusion of mature leaves and bark is used to treat diabetes and gall stones. o A tea made with dried and powdered leaves is taken to relieve asthma. o Heated leaves can treat wounds, abscesses and ear problems, and relieve pain. • Bark o An extract from bark or rags (the non-edible portion of ripe fruits) or roots is used in the treatment of dysentery and release of the placenta after calving in cows. o Ashes produced by burning bark can treat abscesses and ear problems. o Extract from seeds or bark helps digestion. • Other uses o Crushed inflorescence is used to reduce bleeding in open wounds. 3
o Ripe fruits can be used as a laxative. • Seeds o Extract from freshly extracted seeds is used to treat diarrhoea and dysentery. 2.5 Fuel and timber • Jackfruit trees yield valuable timber for making high quality furniture, for house construction, masts, oars and musical instruments. • The fallen leaves and pruned twigs and branches can be used as household fuel. 2.6 Fodder • Leaves are a useful fodder for goats. 2.7 Ecological and environmental value • The jackfruit canopy provides perennial cover to the soil, acting as a shade tree and absorbing the impact of rain on the soil. • Soil fertility is improved if fallen leaves are allowed to rot and incorporated in to the soil. • Weed growth is reduced when leaf mulches are used. • The action of roots particularly taproots growing into soil benefits soil structure by reducing compaction, and facilitates soil conservation. • The tree can reduce the effects of wind planted around a homestead. 4
