Seeds and planting
It can be propagated through seedlings.

Seed rate
The optimum seed rate is 450 g/ha. The crop requires a resting period of one month and sowing should not be delayed further. Seedlings are raised in nursery and transplanted at six leaf stage at a spacing of 50 x 50 cm during June - July. Drench the seedlings with Copper oxy chloride 2.5 gm/lit of water to prevent damping off disease in nursery.

Irrigation should be given once in a week in the first month and later reduced to once in a fortnight.

Apply FYM 10 t/ha and N, P and K at 25, 40 and 80 kg/ha respectively as basal dose. 25 kg of N at second month after planting is required as top dressing.

Plant protection
