Effectiveness of rainfall can also be assessed in terns of monetary returns. This is a rather complicated analysis. The returns depend upon the type of production, use of other inputs such as fertilizers, plant protection measures, soil fertility, weather parameters other than rainfall, infra-structure developed in the area, farm management efficiency and market prices.
