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.

-
Short of potassium Your soil is likely short of potassium.
Add about a quarter more potash (MOP) than the usual dose.
Ask your Krishi Vigyan Kendra what to add for this crop.
