A study on impact of climate change on rice production in Faizabad district of Uttar Pradesh

Abstract

The present paper attempts to study the effect of changes in climatic variables on rice production in Faizabad district of U. P., India. Time series data on rice yield and weekly data of seven weather variables for the crop-season for 20 years covering the period 1990-91 to 2009-10 have been used in the study. Effect of individual variable has been studied by carrying out step-wise regression analysis using weather indices and time trend as regressor variables and rice yield as regressand. It has been found that weighted weather indices of each weather variable including time trend have exhibited significant effect on the rice yield. It has also been found that rise in all seven weather variables except maximum temperature has been detrimental to rice yield during ripening and maturity phase of the crop. The overall results indicate the fact that changes in climatic variables show detrimental as well as beneficial role depending upon the phases of crop production in getting out its final output.
