Growth and decomposition of wheat production in Vidarbha region of Maharashtra state

Abstract

This study was aimed at investigating the “Growth and Decomposition of Wheat Production in Vidarbha”. The study was based on secondary data of area, production and productivity of Wheat in Vidarbha region of Maharashtra. The complete data of Wheat available for all district of Vidarbha region from 1996-97to 2015-16 was split into two sub periods i.e. period-I 1996-97 to 2005-2006 and period -II 2006-07 to 2015-16. The growth rates were calculated by exponential function. The instability in area, production and productivity was measured through Coefficient of variation (CV) and Cuddy Della Valle’s Instability index. The relative contribution of area and yield to change in output was estimated by using Minhas decomposition model. The district wise analysis was carried out for the period-I, Period-II and overall. The compound growth rate of area, production and productivity were positive in almost all the district except Buldhana district, during oveall period. Whereas, the compound growth rates for area were negative indicating decline in area in Vidarbha region during Period I and period II. The coefficient of variation estimated was in the range 35.16 to 62.70 per cent for area and 44.52 to 76.16 per cent for production. Thus, it indicates that the wheat is cultivated traditionally in the region during rabi season. Among the parametric models fitted to the area, production and productivity under Wheat crop, according to the goodness of fit cubic model was found to be best fitted for all the districts of Vidarbha. As regard to region as a whole the highest R2 was recorded in area i.e. 61 per cent than production and productivity. The decomposition analysis for Vidarbha region was estimated the largest area effect on wheat production. It was also observed that for both the period area effect was more pronounce than yield effect and interaction effect. Hence There is need for policy maker to formulate development-oriented policy and researcher to design investigative research activity for promoting sustainable wheat production system in the region for expansion of area under wheat cultivation.
