Water

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

Needs about 810 mm of water here in its growing months. Rain in its months gives about 590 mm it can use in a normal year (440 mm in a dry one), and the soil holds about 0 mm from the monsoon at sowing.

Grows best at 18–30 °C on average, and survives 7–35 °C.

Money

Yield: about 33 quintals an acre, the typical figure across India (your district's own figure looked wrong).

On rain alone it gets about 73% of the water it needs, so the money here is worked at 73% of this yield.

Mandi price at last season's harvest (August–September 2026): about ₹14,250 a quintal across mandis in your state.

This week: about ₹17,000 a quintal, the middle of 3 mandis in your state (latest 13 Nov). At that price an acre would leave about ₹2.9 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 ₹1.1 lakh an acre: about half of what a usual harvest earns (2023–2025), as in farm cost surveys. They are spent whatever the harvest.
