Yield: about 149 quintals an acre, the typical figure across India (no figures for your state).

Mandi price through the year (December 2025–November 2026): about ₹3,000 a quintal across India's mandis.

This week: about ₹3,500 a quintal, the middle of 71 mandis across India (latest 13 Nov). At that price an acre would leave about ₹2.8 lakh a year 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 September.

Typical costs are about ₹2.4 lakh an acre: about half of what a usual harvest earns (2023–2025), as in farm cost surveys. They are spent whatever the harvest.
