Abstract

Field experiments were carried out at College farm, B. A. College of Agriculture, Anand Agricultural University, Anand. The DSSAT v 4.6 CROPGRO-Peanut model was used to predict the phenology of groundnut crop under combinations of three sowing dates and four groundnut cultivars. The model was calibrated with a 2015 dataset of growth and phenological parameters for estimating the genetic coefficients of all four cultivar and was validated with a 2016 dataset of the same parameters. Result found that the model was able to reasonably simulate the pod yield, kernel yield and haulm yield with per cent error ranging (± 10.06) between observed and simulated value for all cultivars under different sowing dates Simulations of yield and yield attributing characters using the calibrated model were found to be quite accurate.
