Cultivation & Propagation

The crop flourishes well in high rainfall and humid conditions. The warm temperatures and long days are favorable for crop growth and production of oil. It is grown under partial shade and also in moderate frost and drought conditions.

Propagation is done through seeds and for fresh plantation, take fresh seeds from the pedigree stock. Raise the seed beds measuring 15 by four by 9 ft size and prepare the soil with farmyard manure of 10 kg per bed. In one hectare of land, 200 to 300 g seeds are required to raise the seedlings for transplantation.

Sow the seeds by mixing with sand at a depth of 2 cm and irrigate the soil with a sprinkler hose. Germination takes place in 10 to 12 days and the seedlings become ready for transplantation by 45 days during leaf stage. Spray 2% of urea solution on the nursery plants before 15 to 20 days of plantation in the field which helps to get healthy seedlings.

To get a fine tilth of land, add 15 t/ha of farmyard manure and other fertilizers as a basal medium. Mix it with the soil. During the summer season, three irrigations in a month are essential and 12 to 15 irrigations are required in a year. Apply mulch for conserving the moisture in the soil and test the irrigation water for any types of contaminants.
