Abstract

Rice (Oryza sativa) is the most important staple food for almost half of the global population. Improvement of rice yield is of global concern and is influenced by a wide variety of regional factors including climate and agricultural management. This research addresses the need to understand the relative influence of these factors and develop geographically explicit determinants of rice yield across Bangladesh. The specific objectives of this study were (a) to assess spatial and temporal variation in rice yield, cropping intensity and means of irrigation, and (b) to evaluate the relative importance of spatio-temporal change in climate, cropping intensity and means of irrigation on rice yield. A database on rice yield, management practices (cropping intensity and means of irrigation) and climate was collected from the Bangladesh Bureau of Statistics and Bangladesh Meteorological Department, respectively, for the years of 1981-2010. Linear mixed models were used to assess the influence of different determinants on rice yield.
