    REGIONAL DISPARITIES OF SELECTED FRUIT CROPS IN TAMIL NADU
    (AAU, Jorhat, 2019-07) R, ANANTH.; Saikia, Hemanta
    Indian agriculture is known for its diversity, which is mainly the result of variations in resource endowments, climate and topography, historical, institutional and socio-economic factors. Regional disparity in agricultural development is referred to as the variations in agriculture performance and productivity. In India, Tamil Nadu has a unique position in Fruit crops production and also it is one of the largest producers of fruit crops in India. In Tamil Nadu, there are 7 Agro-Climatic regions or zones which cover 33 districts. Hence, the study was limited to major fruit crops namely Banana, Sapota, Mango and Guava due to its importance of production. The present study was about the growing tendency in area, production, productivity, regional disparities of the selected fruit crops of different Agro-Climatic regions and factors affecting the selected fruit crop’s production in Tamil Nadu. Time series data of area, production and productivity of the selected fruit crops of Agro-Climatic Regions of Tamil Nadu were collected for twenty years (1996- 97 to 2015-16). Three functions i.e., linear function, quadratic function and exponential function were consider in order to study the growing tendency in area, production and productivity. Best fitted trend equation had been selected based on highest R2 value and lowest MSE value. Regional disparity in crop production was studied with the help of composite index of development. The index was given by selected indicators. The important Factors affecting the selected fruit crop’s production in overall Tamil Nadu was studied by multiple regression analysis. In this study, it was seen that the quadratic function was the best fitted trend equation for area, production and productivity of different regions for the study period 1995-96 to 2015-16 of the selected fruit crops. In case of Banana, the increasing trend of the area was observed in all the Agro-Climatic regions except Southern Zone. The production and productivity was showing the increasing trend in all the zones except High Rainfall Zone. In the case of Sapota, the increasing trend of the area was observed in all the zones except Hilly Zone. The increasing trend of production and productivity was found in all the zones except High Rainfall Zone. In the case of Mango, the increasing trend of area was observed in all the zones except Hilly Zone and High Rainfall Zone and also the increasing trend of productivity was observed in all the zones except North Eastern Zone. Though the decreasing of area and productivity was found in some zones, the increasing trend of production was observed in all the zones. In the case of Guava, the decreasing trend of area was observed in all the zones except North Eastern Zone and High Rainfall Zone. The increasing trend of productivity was observed in all the zones except North Western Zone and Southern Zone. Regarding the production, the increasing trend was observed in North Eastern Zone, Western Zone, Cauvery Delta Zone and High Rainfall Zone and the decreasing trend was observed in remaining zones viz., North Western Zone, Southern Zone and Hilly Zone. By using composite index of development, Western Zone was the high level zone; North Eastern Zone, Cauvery Delta Zone and Southern Zone were high middle level zones in Banana crop. In Sapota crop, Western Zone, North Western Zone and Southern Zone were high middle level zones. In Mango crop, North Western Zone was high level zone; North Eastern Zone and Western Zone were the high middle level zones. In Guava crop, Western Zone was the high level zone followed by North Eastern Zone, North Western Zone and Southern Zone were the high middle level zones. In Banana, Mango and Guava crops, High Rainfall Zone and Hilly Zone were found that low middle level and low level developed zone respectively. By using multiple regression analysis method, area had been identified as the key factor of Banana, Sapota, Mango and Guava crop’s production. In addition to area, average temperature also had been identified as important factor in Guava crop.
