Calibration and validation of CERES-rice model for different rice cultivars at Navsari

For the present study CERES-Rice model was calibrated based on past three years experimental crop data (2009, 2010 and 2011) and subsequently validated wi th crop dat a of t he yea r 2012 .The genetic coefficients were develope d t hrough interactive process for rice genotypes are presente d i n (Tabl e 1).T he different test criteria viz., mean of obse rved and simulated values, root mean square error (RMSE), m ean bi as error (MBE) and mean percent error (PE)were used to evaluate the performance of model for simulation of yield and yield attributes characters of all three rice cultivars.
