Abstract:

Changes in cropping pattern can be seen as the changes in proportion of acreage or the value of production under different crops to total agricultural area or production. The present study has analysed the nature of crop diversification in terms of the changes in cropping pattern with respect to acreage and production distribution. It is observed that share of major crops like paddy, groundnut and cumbu has decreased over the years in the state. However, share of minor crops like maize, black gram, green gram, coconut and fruits and vegetable increased over the years. Different Index like Herfindahl Index (0.42), Simpson Index (0.58) and Entropy Index (1.13) for different crops from 1980-81 to 2014-15 have found fair diversification among crop groups over different time period. Results from transitional probability matrix indicated that the highest retained area is cereals (76 per cent) and lowest retained area share is under cash crops (17 per cent) and this area is diversified towards fruit and vegetable crops to the total cropped area in last ten years.
