How the soil score worksMoney
Yield: about 7.3 quintals an acre, the typical figure in your state (your district's own figure looked wrong).
On rain alone it gets about 81% of the water it needs, so the money here is worked at 81% of this yield.
Mandi price at last season's harvest (December 2025–January 2026): about ₹6,218 a quintal across India's mandis.
This week: about ₹7,560 a quintal, the middle of 9 mandis across India (latest 13 Nov). At that price an acre would leave about ₹21,000 a season after typical costs.

How to make it work
-
Short of potassium Your soil is likely short of potassium.
Add about a quarter more potash (MOP) than the usual dose.
Ask your Krishi Vigyan Kendra what to add for this crop.
-
Short of organic carbon Your soil is likely short of organic carbon.
Add 4 tonnes of compost or farmyard manure per acre before sowing, and plough crop leftovers back in instead of burning them.
Ask your Krishi Vigyan Kendra what to add for this crop.
-
Short of manganese Your soil is likely short of manganese.
Spray manganese sulphate, 5 g per litre of water, on the young crop.
