An experiment was conducted to study crop growth modeling at the paddy field of ICAR- Indian Institute of Water Management during Kharif 2016. The CERES-Rice model of DSSAT 4.5 was used to simulate crop growth and yield; Validation results showed that model predicted number of days to flowering with the RMSE values of 0.98. Four days difference was recorded between observed and simulated days to flowering in different varieties. The model simulated number of days from planting to physiological maturity with RMSE of 0.65. LAI was simulated with RMSE of 0.38 for this cultivar. There was a good agreement between observed and simulated grain yield with RMSE of 0.35 the simulation of total crop biomass at harvest was also correlated with RMSE of 3.41.
