Money

Yield: about 61 quintals an acre, the typical figure in your state (its government crop records list none for your district).

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 (February–March 2026): about ₹3,125 a quintal across mandis in your state.

Prices are usually best in March.

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.
