This paper has a three fold contribution to the existing literature - 1) Indian state level sorghum input and output data for the period 1970-71 to 2000-01 is collected, 2) non-parametric linear programming productivity measures are estimated, and 3) examine the impact of policy variables like percent of high yielding varieties, percent under irrigation, and herfindahl index of seasonal production (rabi and kharif) on productivity using two way random effects panel model

本文有三个褶皱对现有文献的贡献- 1)印度高粱水平输入和输出数据为1970 - 71 - 2000 - 01年收集,2)非参数线性规划效率措施估计,和3)检查政策的影响变量的高产品种,季节性生产的灌溉下,百分比和赫芬代尔指数(拉比和雨季)使用双向随机效应面板模型对生产率
