Onion
Sow in December, harvest around April
Grown on 396 acres here. Priced from mandis across your state.
Only with irrigation: rain gives too little of its water to count on
- Doesn't suit: Too dry without irrigation
- Needs care: Very hot in April
- Needs care: Soil 7/10
Why, and how to make it work Hide details
Water
Too dry to grow on rain alone. It would need irrigation.
Needs about 640 mm of water here in its growing months. Rain gives about 10 mm it can use in a normal year, and 0 mm in a dry year.
Temperature
Grows best at 12–25 °C on average, and survives 4–33 °C.
Here, in its growing months (day / night):
- Dec 29 °C / 15 °C
- Jan 30 °C / 15 °C
- Feb 33 °C / 18 °C (outside its best range)
- Mar 36 °C / 21 °C (outside its best range)
- Apr 38 °C / 24 °C (outside its best range)
Months in orange are outside its best range.
Days in April get hotter than it likes. Time sowing so it flowers before then.
Soil
Soil for Onion: 7 out of 10 (okay).
- The pH here suits it.
- Many fields here are short of nitrogen, which it needs a lot.
- Many fields here are short of potassium, which it needs a lot.
- Many fields here are short of sulphur, which it needs a lot.
Likes pH 6.0–7.0.
How the soil score worksMoney
Yield: about 86 quintals an acre here in this season (district figures).
Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.
Mandi price at last season's harvest (April–May 2026): about ₹995 a quintal across mandis in your state.
This week: about ₹3,861 a quintal, the middle of 4 mandis in your state (latest 13 Nov).
- ₹1,650 2021
- ₹1,280 2022
- ₹1,480 2023
- ₹2,650 2024
- ₹1,490 2025
Prices swing a lot from year to year, so income can be well above or below this range.
Prices are usually best in September.
Typical costs are about ₹42,000 an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
How to make it work
The better districts with similar soil, rain and warmth get 87 quintals an acre. That's a realistic target.
-
Short of nitrogen Your soil is likely short of nitrogen.
Add about a quarter more urea than the usual dose, in two or three splits. A pulse crop in rotation also adds nitrogen.
About 100% of local fields of this crop get it.
-
Short of zinc Your soil is likely short of zinc.
Mix 10 kg of zinc sulphate per acre into the soil before sowing. One dose lasts two or three seasons.
Few local farmers add it to this crop, so it's an easy place to get ahead.
-
Short of iron Your soil is likely short of iron.
Spray ferrous sulphate, 5 g per litre of water, when young leaves turn yellow.
Few local farmers add it to this crop, so it's an easy place to get ahead.
-
Short of boron Your soil is likely short of boron.
Mix 4 kg of borax per acre into the soil before sowing.
Few local farmers add it to this crop, so it's an easy place to get ahead.
What local farmers put on it (share of fields):
- Di-Ammonium Phosphate (DAP) 100%
- Urea 91%
- Urea Ammonium Phosphate 57%
- Muriate of Potash (MOP) 7%
