Planting : Seeds are sown in cool seasons from October to February. Seedlings with 4~5 true leaves at about 20 days old are suitable for transplantation. Spacing of about 30 cm between plants is recommended.

A basal dressing consisting of compost (330 kg/d.c.), peanut meal (75 kg/d.c.) and bone meal (75 kg/d.c.) is recommended.

The first top dressing of peanut meal (35 kg/d.c.) should be applied 10 days after transplanting. Two to three more top dressings of compound fertilizer. (N:P:K:Mg = 12:12:17:2) at the rate of 10 kg/d.c. are required every 10~15 days thereafter.
