摘要:Impact of climate change on crop duration grain and biomass yield were studied under different climate change scenarios using CERES- Rice model under Rajendranagar climatic conditions. Evaluated the impact of elevated temperature and carbon dioxide levels and reduced solar radiation (increased cloudiness) using 40 years of long term weather data of Rajendranagar using CERES-Rice model. The elevated temperature by 1 0 C and 2 0 C increased the number of days to attain anthesis and maturity, and decreased the grain yield by 7.3 and 13.7% under normal planting date respectively. Grain yield has increased when CO 2 increased to 450ppm and 600 ppm. The reduced solar radiation did not show much influence on grain yield of rice
