Why, and how to make it work Hide details
Water
Too dry to grow on rain alone. It would need irrigation.
Needs about 550 mm of water here in its growing months. Rain gives about 0 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 26 °C / 11 °C
- Jan 24 °C / 9 °C
- Feb 28 °C / 13 °C
- Mar 34 °C / 18 °C (outside its best range)
- Apr 38 °C / 23 °C (outside its best range)
Months in orange are outside its best range.
Soil
Soil for Onion: 8 out of 10 (good).
Not in the score: nitrogen and boron.
- The pH here suits it.
- Many fields here are short of potassium, which it needs a lot.
- Most fields here are short of organic carbon.
- Most fields here are short of iron.
Likes pH 6.0–7.0.
How the soil score worksMoney
Yield: about 57 quintals an acre, the typical figure in your state (your district's own figure looked wrong).
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 ₹1,163 a quintal at mandis in your district.
This week: about ₹3,100 a quintal, the middle of 26 mandis in your state (latest 13 Nov).
- ₹1,450 2021
- ₹1,130 2022
- ₹1,200 2023
- ₹2,000 2024
- ₹1,100 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 64 quintals an acre. That's a realistic target.
-
Short of organic carbon Your soil is likely short of organic carbon.
Add 4 tonnes of compost or farmyard manure per acre before sowing, and plough crop leftovers back in instead of burning them.
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.
