Money

Yield: about 3.2 quintals an acre, the typical figure across India (no figures for your state).

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 71% of the water it needs, so the money here is worked at 71% of this yield.

Mandi price at last season's harvest (March–May 2026): about ₹14,855 a quintal across India's mandis.

This week: about ₹11,475 a quintal, the middle of 6 mandis across India (latest 13 Nov). At that price an acre would leave about ₹1,000 a year after typical costs.

Prices are usually best in February.

Typical costs are about ₹25,000 an acre: about half of what a usual harvest earns (2024–2026), as in farm cost surveys. They are spent whatever the harvest.
