Turmeric

Water

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

Needs about 570 mm of water here in its growing months. Rain gives about 410 mm it can use in a normal year, and 330 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 28 °C / 16 °C
• Jul 25 °C / 18 °C
• Aug 24 °C / 17 °C
• Sep 24 °C / 16 °C
• Oct 22 °C / 12 °C (outside its best range)

Money

Yield: about 4.9 quintals an acre, the typical figure in your state (your district's own figure looked wrong).

On rain alone it gets about 72% of the water it needs, so the money here is worked at 72% 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 lose about ₹66,000 a season at 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.
