Water

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

Needs about 460 mm of water here in its growing months. Rain in its months gives about 120 mm it can use in a normal year (50 mm in a dry one), and the soil holds about 200 mm from the monsoon at sowing.

Grows best at 16–24 °C on average, and survives 10–30 °C.

On rain alone it gets about 70% of the water it needs, so the money here is worked at 70% of this yield.

Prices are usually best in November.

Typical costs are about ₹27,000 an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
