Seed Rate for Onion Cultivation

Onion seeds are sown in nursery beds to raise seedlings For common big onions, 8-10 kg seed is sufficient for raising seedlings for one hectare, accomodating 100-110 beds of 3m X 0.6m size each. For broadcasting directly in the field or sowing in the rows, 20-25 kg seeds is enough for a hectare. For multiplier onions 10-12 quintal bulblets are required for planting one hectare.

Best time for sowing early-kharif crop is February-April in South, May-June in Maharashtra and other parts, August-September for late-kharif and October-November for rabi in plains all over the country. In hills, March-April is ideal sowing time. Raised beds of about 3 m long, 0.6 meter wide and 20-30 cm high are prepared. About 70cm distance is kept between 2 beds to carry out operations of watering, weeding etc.
