Assessment of impact of temperature and CO2 on growth and yield of rice crop using DSSAT model has been made to assess the impact of these two parameters on the productivity of rice crop at south Gujarat region. For this purpose CERES-Rice model was used in which the experimental result of rice during kharif, 2016 used as baseline to assess the rice yield under different climatic variability. Crop production is inherently to variability in climate. Temperature and CO2 are two important parameters related to climatic variability, which affect crop yield of a particular region However, on the basis of study carried out in the region, the model was run and rerun for temperature increase or decrease by 1 or 2 0C and CO2 concentration increase or decrease 100 or 200 ppm. The deviation in rice productivity from 2016 was estimated and analysed to assess the effect of temperature and CO2. | Assessment of impact of temperature and CO2 on growth and yield of rice crop using DSSAT model
