Sweet Potato

Water

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

Needs about 490 mm of water here in its growing months. Rain gives about 280 mm it can use in a normal year, and 190 mm in a dry year.

Temperature

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

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

• Jul 33 °C / 24 °C (outside its best range)

Money

Yield: about 76 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 (December 2025): about ₹2,300 a quintal across India's mandis.

This week: about ₹3,200 a quintal, the middle of 73 mandis across India (latest 13 Nov).

Prices are usually best in September.

Typical costs are about ₹55,000 an acre: about half of what a usual harvest earns (2023–2025), as in farm cost surveys. They are spent whatever the harvest.
