Turmeric

Water

Rain falls about 4 irrigations (5 cm each) short in a normal year, so it's risky without water.

Needs about 800 mm of water here in its growing months. Rain gives about 630 mm it can use in a normal year, and 480 mm in a dry year.

Temperature

Grows best at 20–28 °C on average, and survives 18–32 °C.

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

• Jun 38 °C / 26 °C (outside its best range)
• Jul 34 °C / 26 °C (outside its best range)
• Aug 33 °C / 26 °C (outside its best range)
• Sep 33 °C / 24 °C (outside its best range)
• Oct 32 °C / 20 °C
• Nov 28 °C / 13 °C
• Dec 22 °C / 9 °C (outside its best range)
• Jan 20 °C / 8 °C (outside its best range)

Days in June get hotter than it likes. Time sowing so it flowers before then.

Soil

Soil for Turmeric: 7 out of 10 (okay).

• The pH here suits it.
• Many fields here are short of sulphur, which it needs a lot.
• Most fields here are short of nitrogen.
• Most fields here are short of organic carbon.

Likes pH 6.0–7.0.

Money

Yield: about 6.5 quintals an acre, the typical figure in your state (your district's own figure looked wrong).

On rain alone it gets about 79% of the water it needs, so the money here is worked at 79% of this yield.

Mandi price at last season's harvest (February–March 2026): about ₹10,759 a quintal across mandis in your state.

This week: about ₹20,813 a quintal, the middle of 22 mandis across India (latest 13 Nov). At that price an acre would lose about ₹33,000 a season at typical costs.

Prices are usually best in January.

Typical costs are about ₹1.4 lakh an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
