Turmeric

Water

Rain falls about 3 irrigations (5 cm each) short in a normal year, so it's risky without water.

Needs about 920 mm of water here in its growing months. Rain gives about 780 mm it can use in a normal year, and 510 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 37 °C / 26 °C (outside its best range)
• Jul 35 °C / 26 °C (outside its best range)
• Aug 34 °C / 25 °C (outside its best range)
• Sep 34 °C / 25 °C (outside its best range)
• Oct 32 °C / 24 °C (outside its best range)
• Nov 30 °C / 23 °C
• Dec 29 °C / 22 °C
• Jan 30 °C / 21 °C

Months in orange are outside its best range.

Soil

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

Not in the score: organic carbon, sulphur 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 nitrogen.

Likes pH 6.0–7.0.

Money

Yield: about 23 quintals an acre, the typical figure across India (your district's own figure looked wrong).

On rain alone it gets about 85% of the water it needs, so the money here is worked at 85% of this yield.

Mandi price at last season's harvest (February–March 2026): about ₹12,663 a quintal across India's mandis.

This week: about ₹20,950 a quintal, the middle of 22 mandis across India (latest 13 Nov). At that price an acre would leave about ₹2.7 lakh a season after typical costs.

Prices swing a lot from year to year, so income can be well above or below this range.

Prices are usually best in November.

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.
