Important input factors that affect root growth under field conditions have not been included in CSM-CROPGRO-Peanut model, resulting in poor simulation of some rooting traits. Hence, the objective of this study was to optimize root growth factors for obtaining the suitable value with particular genotypes and environments. Two root growth factors including 1) fraction partitioning to leaf (YLEAF) and 2) root growth factor in soil layers were adjusted. Root mean square error (RMSE) and index of agreement (d) that were the statistical agreement between observed data and simulated data were used for considering the best fit values of root growth factor. The statistical agreement between observed and simulated data of root dry weight and root length density...
