How to Grow the Jackfruit Tree - Field Management - 1. Weeding and mulching Keep young trees weed free at least for the first 3–4 years. You may plough and harrow the spaces between the trees, at the beginning and end of the rainy season if tools are available. Apply mulch around the trees. M A N A G E M E N T 2. Watering Extra watering is not normally needed, except: Water newly planted trees during dry periods for 3–4 years or until the plants are growing strongly. For mature trees, watering is recommended through dry periods during bloom and fruit development. Build a low ring of soil around the tree to retain water around the roots. 3. Pruning and training In grafted trees, prune the lower branches to obtain a longer trunk. Prune weak, dead and diseased branches and remove parasitic plants, generally at the end of rainy season. Remove the inner branches of the canopy to allow in light and air, to minimize pest and disease attack. 6b Grafted tree without pruning Grafted tree pruned and trained to have longer trunk © 2006 Southampton Centre for Underutilised Crops, UK

See page 14 in Part 1. Cow manure is dried in the sun and added to the soil around the tree. 5. Insect pests Shoot and fruit borer (Diaphania caesalis), and bud weevil (Ochyromera artocarpi) are the two major pests of jackfruit. To prevent egg-laying of shoot and fruit borer, cover fruits with polythene bags and remove and destroy all affected parts. Spraying of carbaryl @ 4 g/l of water during flowering may be necessary. To control bud weevil remove all infested shoots, flower buds and fruits. 6. Diseases Blossom rot or fruit rot or stem rot caused by a fungus, Rhizopus artocarpi, is a serious disease, which may cause 15– 32% crop loss. Collect and destroy all fallen leaves and fruits under the tree. Larva Adult insect Shoot and fruit borer insect and fruit damage Consult an extension officer before spraying.
