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 ₹6,448 a quintal across mandis in your state.
This week: about ₹7,560 a quintal, the middle of 9 mandis across India (latest 13 Nov).

How to make it work
The better districts with similar soil, rain and warmth get 7.8 quintals an acre. That's a realistic target.
