*5.5. Statistical Indices for AquaCrop Model Evaluation*

The statistical indices derived for evaluating the AquaCrop model's performance in predicting soil water content, yield, canopy cover percent, biomass, and water productivity (*WP*) of barley genotypes under different saline water regimes across different environments are given in Table 5. All statistical parameters depict a strong correlation between simulated and observed values for model calibration and evaluation periods. The correlation between all statistical parameters remained almost the same for the calibration and evaluation period, which indicates the robustness of the model prediction. Based on the model calibration and evaluation results, the model was found robust enough to calculate different scenarios.
