How the soil score worksMoney
Yield: about 43 quintals an acre here (district figures).
Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.

This week: about ₹4,000 a quintal, the middle of 24 mandis in your state (latest 13 Nov).

How to make it work
The better districts with similar soil, rain and warmth get 107 quintals an acre. That's a realistic target.
-
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.
About 100% of local fields of this crop get it.
-
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.
Few local farmers add it to this crop, so it's an easy place to get ahead.
What local farmers put on it (share of fields):
- Urea 100%
- Di-Ammonium Phosphate (DAP) 90%
- Zinc Sulphate Heptahydrate / Monohydrate 90%
- Triple Super Phosphate (TSP) 10%
