Abstract:
Global climate change has potentially grave consequences for rice production and, consequently global food security. Negative effects on yields and availability of rice will directly translate into major shortages. Hence, it is essential to study the impact of climate change on Kharif rice yield. This study was conducted to assess the impact of climate change on productivity of rice cv. Hasanta in three future scenarios namely 2030, 2050, 2070 for Khordha district of Odisha, using four global climate change Representative Concentration Pathways (RCPs) scenarios namely 2.6, 4.5, 6.0 and 8.5. Weather parameters for climate change scenarios include projection of rainfall, maximum temperature, minimum temperature and radiation for Khordha district by using Mark Sim GCM -DSSAT weather file generator. In this study growth, development and yield of four rice cultivars are verified transplanted under four different dates of planting. The experiment were laid out in split plot design with four dates of transplanting in main plots and four varieties in sub plots with three replications.
