Onion stage by stage
Onion has a shallow, weak root system, so it depends on soil that stays loose and moist. Growers bring us small or uneven bulbs, leaf tips drying early and onions that rot in storage.
Main growing areas: Maharashtra, Karnataka, Madhya Pradesh, Gujarat and Rajasthan.
Nursery and transplanting
About the first 6 to 8 weeksHealthy, even seedlings and moist soil at transplanting give an even crop.
Leaf growth
About 1 to 2 months after transplantingEach healthy leaf adds a ring to the bulb. Leaf loss now means smaller bulbs.
Bulbing
About 2 to 3 monthsBulbs swell. Steady water and potash matter most; stop excess nitrogen.
Maturity and curing
Harvest and afterNecks fall over. Good curing decides how long onions keep.

Onion farmers in their own words
Onion questions
Why are my onions small?
Small bulbs follow stress during leaf growth and bulbing: dry spells, weak roots, leaf disease or poor nutrition.
Why do my onions rot in storage?
Poor curing, harvesting too early, too much late nitrogen and bruising all shorten storage life.
