Turmeric

Water

Too dry to grow on rain alone. It would need irrigation.

Needs about 860 mm of water here in its growing months. Rain gives about 130 mm it can use in a normal year, and 90 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 40 °C / 27 °C (outside its best range)
• Jul 36 °C / 27 °C (outside its best range)
• Aug 35 °C / 26 °C (outside its best range)
• Sep 35 °C / 24 °C (outside its best range)
• Oct 33 °C / 18 °C
• Nov 28 °C / 12 °C (outside its best range)
• Dec 23 °C / 7 °C (outside its best range)
• Jan 19 °C / 6 °C (outside its best range)

Nights in January can bring frost. When frost is forecast, water the field lightly in the evening.

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

Soil

Soil for Turmeric: 8 out of 10 (good).

Not in the score: nitrogen.

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

Likes pH 6.0–7.0.

Money

Yield: about 23 quintals an acre, the typical figure across India (no figures for your state).

Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.

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

This week: about ₹20,813 a quintal, the middle of 22 mandis across India (latest 13 Nov).

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.
