The results showed that this model is very sensitive to transpiration crop coefficient and low to medium sensitive to other input parameters. Normalized root mean square errors (NRMSE) were 0.10, 0.04, 0.11 and 0.04 for yield, biomass, water use efficiency and harvest index, respectively. The values of agreement index (d) for the all parameters were greater than 0.98. Although, AquaCrop model tended to overestimate outputs; however, the simulation results could be acceptable. %U https://ijswr.ut.ac.ir/article_68187_5c3797c4ef32686e05787520d9376e4e.pdf
