On rain alone it gets about 82% of the water it needs, so the money here is worked at 82% of this yield.

Mandi price at last season's harvest (September–October 2026): about ₹8,700 a quintal across mandis in your state.

This week: about ₹8,965 a quintal, the middle of 22 mandis across India (latest 13 Nov). At that price an acre would leave about ₹11,000 a season after typical costs.

Prices are usually best in November.

Typical costs are about ₹9,000 an acre: about half of what a usual harvest earns (2023–2025), as in farm cost surveys. They are spent whatever the harvest.
