Money

Yield: about 1.1 quintals an acre, the typical figure across India (your district's own figure looked wrong).

Mandi price at last season's harvest (August–September 2026): about ₹8,600 a quintal across India's mandis.

This week: about ₹9,750 a quintal, the middle of 3 mandis across India (latest 12 Nov). At that price an acre would leave about ₹7,000 a season after typical costs.

Prices are usually best in October.

Typical costs are about ₹4,000 an acre: about half of what a usual harvest earns (2023–2025), as in farm cost surveys. They are spent whatever the harvest.
