How the soil score worksMoney
Yield: about 7.5 quintals an acre, the typical figure across India (no figures for your state).
Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.
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).
- ₹4,670 2021

How to make it work
-
Short of nitrogen Your soil is likely short of nitrogen.
Add about a quarter more urea than the usual dose, in two or three splits. A pulse crop in rotation also adds nitrogen.
Ask your Krishi Vigyan Kendra what to add for this crop.
