The practice of wrong intercropping is very common. The farmer thinks that the revenue of citrus will be far later so that I should use the intercropping technique for quick revenue.

Commonly, fodders are cultivated among the citrus trees, which means the destruction of a citrus orchard with their own hands. Nutrition and water schedule are far different in between the citrus and fodders. Fodders needs more water while citrus is water sensitive crop, it needs neither less nor over water stress. It is suggested that those crops should be cultivated which are non-exhaustive crops.
