Abstract:
This study aims to analyze the effect of monthly rainfall and monthly temperature on kharif rice yield of Puri district, Odisha. Block wise rainfall data were analyzed to find the variability of rainfall over the district. The block wise rainfall data were collected from Special Relief Commissioner of Odisha. Temperature data were collected from India Meteorological Department, Pune, for the district and yield data of kharif rice were collected from Directorate of Economics and Statistics, Government of Odisha. Block wise rainfall analysis was done using SAS and Weather Cock. Linear regression analysis was performed through SAS to find out the effect of seasonal rainfall and temperature on kharif rice yield. The study showed that mean annual rainfall and rainy days were 1491mm and 57 days respectively. The variability of annual rainfall in the district is about 33% CV and the variability of annual rainy days is 19% CV. Variations on both rainfall and temperature were found not to directly relate to the variations noticed in the yield of kharif rice of Puri district.
