The book is comprehensive analysis of the growth pattern, development, disparities, convergence and determinants of Agriculture in Uttar Pradesh spanning over 50 years from 1960-2010, covering 35 crops and 85 districts in the state (including Uttarakhand). It captures the change dynamics of temporal and spatial dimensions of agricultural performance over the different policy regimes; pre green and green revolution as well as post reform period. Besides measuring the growth and development, the inter-district disparities are examined using standard inequality measures of Gini coefficient, coefficient of variation, ratio of top to bottom quintile productivity, top to bottom quintile shares. Dynamics of disparity has been studied by analysing the sigma convergence, beta unconditional convergence, beta conditional convergence and club convergence approaches. Using panel data model, the role of technological, informational, institutional, infrastructure and idiosyncratic factors has been examined as determinant of temporal and spatial differentials in agriculture development in the state.
