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.
-
Short of boron Your soil is likely short of boron.
Mix 4 kg of borax per acre into the soil before sowing.
