How to make it work
The better districts with similar soil, rain and warmth get 96 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.
-
Short of boron Your soil is likely short of boron.
Mix 4 kg of borax per acre into the soil before sowing.
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):
- Di-Ammonium Phosphate (DAP) 100%
- Urea 100%
- Zinc Sulphate Heptahydrate / Monohydrate 55%
