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 (January–February 2026): about ₹3,338 a quintal across India's mandis.

Prices swing a lot from year to year, so income can be well above or below this range.

Prices are usually best in November.
