How the soil score worksMoney
Yield: about 57 quintals an acre, the typical figure in your state (no recent yield figures for your district).
Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.

How to make it work
-
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.
-
Short of zinc Your soil is likely short of zinc.
Mix 10 kg of zinc sulphate per acre into the soil before sowing. One dose lasts two or three seasons.
About 12% of local fields of this crop get it.
-
Short of iron Your soil is likely short of iron.
Spray ferrous sulphate, 5 g per litre of water, when young leaves turn yellow.
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 94%
- Di-Ammonium Phosphate (DAP) 42%
- Zinc Sulphate Heptahydrate / Monohydrate 12%
- Muriate of Potash (MOP) 11%
