Water

Rain falls about 2 irrigations (5 cm each) short in a normal year, so it's risky without water.

Needs about 300 mm of water here in its growing months. Rain in its months gives about 50 mm it can use in a normal year (30 mm in a dry one), and the soil holds about 170 mm from the monsoon at sowing.

Temperature

Grows best at 18–28 °C on average, and survives 10–38 °C.

Here, in its growing months (day / night):

• Oct 28 °C / 19 °C
• Nov 24 °C / 14 °C
• Dec 21 °C / 10 °C (outside its best range)
• Jan 21 °C / 8 °C (outside its best range)
• Feb 23 °C / 10 °C (outside its best range)

Months in orange are outside its best range.

Soil

Likes pH 5.0–7.0. We have no pH figures for this place.

Money

Yield: about 38 quintals an acre, the typical figure across India (no figures for your state).

On rain alone it gets about 75% of the water it needs, so the money here is worked at 75% of this yield.

Mandi price at last season's harvest (February–March 2026): about ₹2,388 a quintal across India's mandis.

Prices are usually best in September.

Typical costs are about ₹55,000 an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
