Decomposition analysis of major cereal crops in different agroclimatic regions of Chhattisgarh

Abstract

The present investigation relates to different agro climatic regions of Chhattisgarh, where paddy is the competing crop to other kharif crops. The entire Chhattisgarh state is studied, considering its three agro climatic zones which includes 18 districts of Chhattisgarh (At present 27 districts, have merged and made 18 districts) as units of investigation. Secondary data collected from different sources were used for the research work, for the period 2000-01 to 2014-15. Paddy is the principal crop in Chhattisgarh and along with paddy, maize and wheat are also studied in this investigation, so as to know the position of these crops at present as compared to paddy. For the estimation of the contribution of area and yield with change in production, the decomposition model has been used. The result of the decomposition analysis showed that the yield effect is dominating over area effect in all the agro climatic regions, state and in all the three crops, except in Bastar Plateau where area contributes more in production than yield in case of wheat. Paddy reveals highest yield effect as well as lowest area effect in comparison to maize and wheat in Chhattisgarh state.
