Genetic coefficient and validation of DSSAT model for cotton under different growing environments

The model performance in respect of phenology was good with error of ±5% for all the three cotton cultivars and growing environments. Also the model performance was within acceptable range of ±10.0% for LAI, seed cotton yield and biomass for all the cultivars and growing environments. But the model performance was not within acceptable range for the crop sown in 1st week of June.
