摘要: The present study estimates the influence of climatic and non-climatic factors on mean yield variability sugarcane crop in different weather seasons (e.g., rainy, winter summer) India. Sugarcane mean-yield for fourteen major growing states from agro-ecological zones are delimitated panel data during 1971-2009. Regression coefficient production function (i.e. risk increasing or decreasing inputs) has been estimated through log-linear regression model with help Just Pope (stochastic) specification. Empirical results based feasible generalise least square (FGLS) estimations shows a significant effect rainfall, maximum minimum temperatures variability. Whereas, average temperature summer rainy season have negative statistically impact yield. positively gets affected season.
