Sowing of seeds and lifting of seedlings
Seeds are sown in the seedbed between February and April. However, when the seeds are sown in October-November, flowering starts after a few days. Row cultivation requires 4-5 kg of seed per hectare of land. However, 8-10 kg seed per hectare is required for scattered sowing. After soaking the seeds in water for 24 hours and tying them in a dry thin cloth for 12 hours, the seeds germinate. Rotten dung in the seedbed is sifted with manure. It is better to use furadan in the seedbed to control different types of insects and worms. Later the seeds are spread evenly in the seedbed and 0.4-0.5 cm above it. The seedbed has to be pressed by hand by applying loose soil. Other care is done including weeding in the seedbed. When the seedlings are 40-45 days old, it is suitable for planting in the main land. After lifting the seedlings, about one-third of the seedlings have to be pruned and planted. This results in less water coming out of the seedlings after planting and the seedlings stick well to the soil. 7-8.5 lakh saplings are required for one hectare of land.
