Turmeric

Water

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

Needs about 950 mm of water here in its growing months. Rain gives about 840 mm it can use in a normal year, and 490 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 / 27 °C (outside its best range)
• Jul 32 °C / 25 °C (outside its best range)
• Aug 31 °C / 25 °C
• Sep 32 °C / 25 °C (outside its best range)
• Oct 33 °C / 22 °C
• Nov 31 °C / 18 °C
• Dec 30 °C / 15 °C
• Jan 31 °C / 15 °C

Months in orange are outside its best range.

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

Soil

Soil for Turmeric: 9 out of 10 (good).

Not in the score: zinc, iron, copper and manganese.

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

Likes pH 6.0–7.0.

Money

Yield: about 29 quintals an acre, the typical figure in your state (your district's own figure looked wrong).

On rain alone it gets about 89% of the water it needs, so the money here is worked at 89% of this yield.

Mandi price at last season's harvest (February–March 2026): about ₹10,990 a quintal across mandis in your state.

This week: about ₹13,589 a quintal, the middle of 3 mandis in your state (latest 13 Nov). At that price an acre would leave about ₹2.1 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.
