OriginNangka is native to parts of South and Southeast Asia, and is believed to have originated in the southwestern rain forests of India, in present-day Kerala and coastal Karnataka.
DescriptionNangka is said to be the largest tree-borne fruit in the world, with its diameter being at least 25 cm. The yellow fruit is crispy, having a pineapple and banana taste, some say it smells similar to durian.
Growth HabitatNangka is adapted only to humid tropical and near-tropical climates.
FoliageEvergreen, alternate, glossy, somewhat leathery leaves to 22.5cm long, oval on mature wood, sometimes oblong or deeply lobed on young shoots.
FlowersThe tree is monoecious: tiny male flowers are borne in oblong clusters 5-10 cm in length; the female flower clusters are elliptic or rounded.
FruitsLargest of all tree-borne fruits, the Nangka may be 20-90 cm long and 15-50 cm wide, and the weight ranges from 4.5-20 or even as much as 50 kg. The fruit has a green exterior rind covered with small cone-like points. The bulb-like or pod-like fruits which enclose a smooth seed are attached to a pithy core. The fruits are surrounded by many narrow ribbons mainly attached to the interior part of the rind. The fruits are crisp with a pineapple, banana flavour and the seeds taste like chestnuts. Fruit pulp colour varies from amber to yellow, dark yellow or orange.
Harvest Immature fruit is usually 1 to 3 months old, are green and may be harvested for cooking. Maturing fruits lighten in colour and usually develop a strong aroma and the rind spines flatten and widen. Green fruits have a solid sound when tapped whereas ripe fruits have a hollow sound. Because sticky latex may exude from cut surfaces, knives blades need to be coated in oil to extract the fruit.
SoilThe Nangka tree flourishes in rich, deep soil of medium or open texture, sometimes on deep gravelly or laterite soil. It will grow, but more slowly and not as tall in shallow limestone.
PruningWith annual pruning the tree is easily maintained at a height and spread of 2m to 3m. Pruning should be done once per year following harvest of the major crop, or towards the end of the warm, humid season.
FertilizationSoils should be as fertile as possible and will benefit from the addition of plant mulch to the soil surface. The tree is not tolerant of salt in the soil, water or air. Fertilization is best done by three applications per year in March, July and September of N:P:K 8-3-9.
PropagationGrafting is the most reliable means of propagating a desired cultivar. Grafting joins together a piece of a mature, bearing tree (scion) with a separate seedling tree (rootstock) to form a permanent union. The scion forms the canopy of the tree and the rootstock the lower trunk and roots. Grafted trees will bear fruit in 2 to 3 years after planting and have a more spreading and open canopy than seedling trees.
