Land Preparation

Plough the field to good tilth. Remove all pebbles and stones. Incorporate FYM or organic manure at 10-15 t/ha. Prepare raised beds of convenient length and breadth to facilitate drainage.

Planting

One hectare requires 1000-1500 kg of seeds. Take small pits on the seedbed and plant 5 cm long rhizome bits. Cover rhizome with FYM and mulch the seedbed with leaves or straw. The optimum spacing is 30 x 20 cm under poor fertility and 40 x 30 cm under good fertility conditions.

Propagation

It is propagated vegetatively by rhizomes and by tissue culture methods.
