Harvesting: Stop irrigation two weeks before harvest. After harvest keep the bulb in the field for curing for 5- 6 days along with tops. Cover the bulbs to avoid sun scalding. After proper drying remove roots and neck, don’t cut the neck close to bulb.
Note 1 : If transplanted late leads to premature bolting.
Note 2 : If seed is drilled / direct sown or broadcasted in the field, need good moisture level for germination and growth minimum upto 20 - 30 days.
Note 3 : Do not broadcast or drill seed in the field if there is no facility of irrigation / drip or sprinkler.
Note 4: Excess Nitrogenous fertilizer leads to thick necks & splits
