Climate change and agricultural sector are inseparable. The paper focuses on the interrelationship between crop production and climate change in general and effect of weather parameters on rice productivity. Increased population increases demand for food which has to be met through increased production/or productivity. Increase production of the rice crop and its residues increases emission of the greenhouse gas methane (CH4). Variations in weather parameters viz. rainfall, temperature, relative humidity and sunshine during the study period 1999–2000 to 2013–14 could be observed through Linear trend analysis. There exists positive correlation between selected weather parameters and productivity of rice. Highest variation in rice productivity was due to sunshine hour (19%). Multiple regression analysis revealed that rainfall, temperature, relative humidity, and fertilizers have significant effects on the productivity of the crop.
