Sow in July, harvest around December

This season's sowing time (July–August) is over.

Grown on 22,330 acres here. Sold at 5 mandis in your district.

₹60,000–₹90,000

per acre a season, before costs

After typical costs: ₹36,000–₹65,000 an acre a season

Needs care: Risky: 7 irrigations short
Suits: Ideal temperatures
Suits: Soil 8/10

Why, and how to make it work

Water

Rain falls about 7 irrigations (5 cm each) short in a normal year, so it's risky without water.

Needs about 610 mm of water here in its growing months. Rain gives about 310 mm it can use in a normal year, and 170 mm in a dry year.

Temperature

Grows best at 20–30 °C on average, and survives 15–39 °C.

Here, in its growing months (day / night):

Jul 33 °C / 26 °C
Aug 32 °C / 25 °C
Sep 33 °C / 24 °C
Oct 35 °C / 22 °C
Nov 33 °C / 17 °C
Dec 30 °C / 13 °C

Soil

Soil for Castor Seed: 8 out of 10 (good).

The pH here suits it.
Many fields here are short of boron, which it needs a lot.
Most fields here are short of nitrogen.

Likes pH 6.0–7.5.

How the soil score works

Money

Yield: about 12 quintals an acre here in this season (district figures).

Mandi price at last season's harvest (December 2025–January 2026): about ₹6,256 a quintal at mandis in your district.

This week: about ₹7,560 a quintal, the middle of 9 mandis across India (latest 13 Nov). At that price an acre would leave about ₹66,000 a season after typical costs.

Average mandi price each year (₹ a quintal):

₹4,930 2021
₹7,050 2022
₹5,870 2023
₹5,710 2024
₹6,250 2025

Prices are usually best in July.

Typical costs are about ₹24,000 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 12 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.

Ask your Krishi Vigyan Kendra what to add for this crop.
Short of boron Your soil is likely short of boron.

Mix 4 kg of borax per acre into the soil before sowing.

Ask your Krishi Vigyan Kendra what to add for this crop.

Semilooper

Pest

Look for

Leaves eaten by green caterpillars that move in loops.

What to do first

Pick off caterpillars; spray when they are many. Follow the label or your KVK for the dose.
Capsule borer

Pest

Look for

Webbed spikes with caterpillars boring into the capsules.

What to do first

Remove webbed spikes; spray when damage spreads. Follow the label or your KVK for the dose.
Wilt

Disease

Look for

Plants wilt and dry; brown streaks inside the stem.

What to do first

Grow a resistant variety and rotate crops.
Grey mould

Disease

Look for

Grey fungal growth on the spikes in rainy weather.

What to do first

Spray carbendazim when rain is forecast at flowering. Follow the label or your KVK for the dose.

− Costs about half of what a usual harvest earns (2024–2026), as in farm cost surveys: −₹24,100

This week castor seed sells at about ₹7,560 a quintal: India's middle price at 9 mandis, latest 13 Nov. At that price an acre would leave about ₹33,200 a season.

A good year or field earns about a fifth more, a poor one a fifth less: ₹37,700 to ₹56,500 income an acre. Costs stay the same either way.
