Money

Yield: about 23 quintals an acre, the typical figure across India (your district's own figure looked wrong).

Mandi price at last season's harvest (February–March 2026): about ₹12,663 a quintal across India's mandis.

This week: about ₹20,813 a quintal, the middle of 22 mandis across India (latest 13 Nov). At that price an acre would leave about ₹3.4 lakh a season after typical costs.

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

Prices are usually best in November.

Typical costs are about ₹1.4 lakh an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
