Measurement of Productivity and Liability Level of Crops

Crop productivity is the capacity of an area to produce crops; a manifestation of complex interaction of various factors of production that together determine the existing condition of the farm environment. Without proper idea of the present productivity level, effective measures for further improvement cannot be initiated. Geographers and agricultural economists have long been engrossed in measuring agricultural productivity. Here I discuss a new method of measuring crop productivity, i.e. determining crop productivity level of an area with respect to the maximum achievable productivity limit under existing conditions of the farm environment. The method also measures the productivity deficiency level of various crops which makes the selection of liable crops much more sound and logical, and is helpful to formulate both the overall and crop-specific developmental strategies. Standard classes of crop productivity, yield achievement, yield deficit and crop liability levels have been prepared separately based on their index values.
