Description
Soil and climate
Deep well drained soil is necessary for jack cultivation. Soil pH around 5.5 at the time of planting is desirable. Otherwise treat the soil with 1% Aluminium sulphate in the pit to reduce the pH. The crop comes up well in the plains and up to an elevation of 1200 m.
Propagation
Soft wood grafting: Large scale propagation of jack can be done by cleft grafting during July-August on 4 month old seedling rootstock
Preparation of field and planting
Dig pits of 1 m x 1 m x 1 m. Fill up the pits with top soil mixed with 10 Kg of FYM and 1 Kg of neem cake per pit. Plant preferably grafts during June – December at 8 x 8 m spacing.
