Money

Yield: about 1.9 quintals an acre, the typical figure across India (your district's own figure looked wrong).

A new planting gives its first real harvest after about 3 years. The money here is for plants already bearing.

On rain alone it gets about 83% of the water it needs, so the money here is worked at 83% of this yield.

Mandi price at last season's harvest (December 2025–March 2026): about ₹65,872 a quintal across India's mandis.

This week: about ₹68,511 a quintal, the middle of 33 mandis across India (latest 13 Nov). At that price an acre would leave about ₹45,000 a year after typical costs.

Prices are usually best in November.

Typical costs are about ₹65,000 an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
