Abstract

Onion is one of the important bulbous vegetable crop grown in India and it is a vital constituent of Indian cookery. Indian average productivity is 16.80 Mt/ha.  However when compared to other countries, the Indian average yield is very low. The main difference between the bulb and seed propagated types is, investment on seed component.  In bulb propagated type, farmer requires 500 to 600 kg of seed bulbs for planting an acre which is higher in cost. Whereas in seed propagated type, it requires only one kg of seeds for an acre which is cheaper as compared to seed bulbs. This will minimize the cost of cultivation, reduction in diseases incidence, enhance the drought tolerance and more income to the farming community.
