Water

Too dry to grow on rain alone. It would need irrigation.

Needs about 510 mm of water here in its growing months. Rain in its months gives about 10 mm it can use in a normal year (0 mm in a dry one), and the soil holds about 10 mm from the monsoon at sowing.

Money

No yield records for this crop yet.

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 (April–May 2026): about ₹5,068 a quintal across India's mandis.

Prices are usually best in June.
