Turmeric

Water

Rain falls about 9 irrigations (5 cm each) short in a normal year, so it's risky without water.

Needs about 990 mm of water here in its growing months. Rain gives about 560 mm it can use in a normal year, and 390 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):

• May 43 °C / 28 °C (outside its best range)
• Jun 41 °C / 29 °C (outside its best range)
• Jul 34 °C / 26 °C (outside its best range)
• Aug 32 °C / 25 °C (outside its best range)
• Sep 34 °C / 25 °C (outside its best range)
• Oct 35 °C / 20 °C
• Nov 30 °C / 13 °C
• Dec 26 °C / 9 °C (outside its best range)

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

Not in the score: phosphorus.

• The pH here suits it.

Money

Yield: about 15 quintals an acre, the typical figure in your state (your district's own figure looked wrong).

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 (January–February 2026): about ₹16,925 a quintal across mandis in your state.

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

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.
