Water

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

Needs about 870 mm of water here in its growing months. Rain gives about 750 mm it can use in a normal year, and 530 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 31 °C / 24 °C
• Aug 30 °C / 24 °C
• Sep 31 °C / 24 °C
• Oct 32 °C / 20 °C
• Nov 30 °C / 14 °C
• Dec 26 °C / 10 °C (outside its best range)
• Jan 25 °C / 9 °C (outside its best range)

• 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).

On rain alone it gets about 87% of the water it needs, so the money here is worked at 87% of this yield.

Mandi price at last season's harvest (March 2026): about ₹21,426 a quintal at mandis in your district.

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 ₹1.3 lakh a season after typical costs.

Prices are usually best in October.

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.
