Analysis of Total Factor Productivity of Important Crops in Rajasthan

Abstract

newline The study entitled Analysis of Total Factor Productivity of Important Crops in Rajasthan was aimed to study temporal changes in area, production and productivity, growth of output, input and TFP (total factor productivity) index, factors responsible for temporal changes in production and economics of selected crops. Eleven crops were taken for the present study. The crops included were wheat, barley, gram, rapeseed and mustard, cotton, bajra, maize, soybean, sesamum, moong, and urad. newlineTo analyze the growth of output, input, total factor productivity indices and factors responsible for temporal changes in production of the selected crops over the past 16 years 2000-01 to 2015-16 were computed. For temporal changes in Rajasthan time series data on area, production and yield per hectare of selected crops were collected from 1976-77 to 2018-19. For profitability analysis of the selected crops, the cost of cultivation data was collected and compiled for the period from 2000-01 to 2015-16. newlineIn the present study, the Tornquist Theil Index was used for calculating the total output index (TOI), total input index (TII) and the total factor productivity index (TFPI). Compound growth rates were worked out using the exponential function. Cobb-Douglas production function was employed to assess the effects of various inputs such as seed, fertilizer, manure, irrigation, plant protection, human and bullock labour. newlineThe investigation revealed that the farmers of Rajasthan had shifted their cultivation from barley, gram and sesamum to crops namely moong, urad, soybean, rapeseed and mustard and wheat. The area under wheat, maize, bajra, cotton, moong, urad, soybean and rapeseed and mustard had recorded increased during the study period. Production and productivity of all the selected crops of Rajasthan improve substantially during the last four decades. Total factor productivity (TFP) of cotton, sesamum, bajra and moong had increased at the rate of 3.80, 2.71, 2.56 and 2.34 per cent per annum, respectively. This indicated goo
