Summer/ rabi Onion is more commonly practiced for an irrigated crop, resulting in a high yield with large sized bulbs. Seedlings are first raised in the nursery. For summer/ rabi crop in India October to November is recomonded as sowing time. In Maharashtra it is transplanted during November to December. (Anon, 2018). About 10 to 12 Kg. seed is required to raise seedlings for one hectare transplanting. The seedlings are ready for transplanting 45-60 days after sowing. Over-aged seedlings result in bolting, taking longer time to start new growth. The spacing 15 x 10 cm. (row to plant) is recomonded for optimum population and higher yield.
