Sow in December, harvest around April

No figures for your district: its government crop records list no area or yield for this crop. Sold at 2 mandis in your district.

Only with irrigation: rain gives too little of its water to count on

  • Doesn't suit: Too dry without irrigation
  • Suits: Ideal temperatures
  • Suits: Soil 8/10
Why, and how to make it work

Water

Too dry to grow on rain alone. It would need irrigation.

Needs about 500 mm of water here in its growing months. Rain gives about 30 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 / 13 °C
  • Jan 24 °C / 10 °C
  • Feb 27 °C / 13 °C
  • Mar 32 °C / 18 °C
  • Apr 34 °C / 22 °C (outside its best range)

Months in orange are outside its best range.

Soil

Soil for Onion: 8 out of 10 (good).

  • Soil here is often more acidic than it likes.
  • Many fields here are short of nitrogen, which it needs a lot.
  • Most fields here are short of boron.

Likes pH 6.0–7.0.

How the soil score works

Money

Yield: about 76 quintals an acre, the typical figure in your state (its government crop records list none for your district).

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 ₹1,600 a quintal at mandis in your district.

This week: about ₹4,350 a quintal, the middle of 2 mandis in your district (latest 13 Nov).

Average mandi price each year (₹ a quintal):
  1. ₹2,350 2021
  2. ₹1,700 2022
  3. ₹2,050 2023
  4. ₹2,750 2024
  5. ₹1,700 2025

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

  • 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):

  • NPK Mixture 100%
  • Urea 100%
  • Muriate of Potash (MOP) 96%

For most fields

Urea nitrogen
83 kg about 1¾ bags of 45 kg
DAP phosphate
35 kg about ¾ of a 50 kg bag
MOP potash
40 kg about ¾ of a 50 kg bag

Sulphur: 12 kg for one acre, from about 65 kg of gypsum or 100 kg of single super phosphate

Give the DAP and MOP at sowing, and the urea in two or three doses. If your soil card says a nutrient is low, add about a quarter more of it.

  • Thrips
    Pest

    Look for

    Silvery-white streaks on leaves; tips dry.

    What to do first

    Use blue sticky traps; spray when thrips are many. Follow the label or your KVK for the dose.

  • Purple blotch
    Disease

    Look for

    Purple spots with yellow edges on the leaves.

    What to do first

    Spray mancozeb when spots appear. Follow the label or your KVK for the dose.

  • Stemphylium blight
    Disease

    Look for

    Yellow-orange streaks on the leaves that turn brown.

    What to do first

    Spray mancozeb when streaks appear. Follow the label or your KVK for the dose.

  • Basal rot
    Disease

    Look for

    Bulbs rot from the base, in the field and in store.

    What to do first

    Rotate crops and cure bulbs well before storing.

Where it grows most

The districts with the most area in recent years. The map colours every district growing it on at least 100 ha by yield; the numbers mark these districts.

District figures cover only 22% of India's onion area, so the districts aren't listed. The states show where it grows.

Soil and yield

How district soil tests line up with this crop's yields across India.

Onion yields tend to be higher in districts with

  • More soil that is neutral moderate 340 districts

Onion yields tend to be lower in districts with

  • More soil that is acidic moderate 340 districts

A pattern is not proof that soil causes the difference.
