Abstract

In order to evaluate the AquaCrop model and investigate the productivity of Rice production under Irrigation management and Planting date, a split plot experiment based on a randomized complete blocks design with three replications was carried out on a local cultivar (Hashemi) in Rice Research Institute of Iran, in Rasht during 2016-2017. Irrigation interval was considered as the main factor in four levels including full flooding, 5, 10 and 15 days Irrigation intervals, and transPlanting date was assigned to subplots at three levels (April, 21st, May, 11th and May, 31st). Simulated and observed values of grain yield and biological yield were evaluated based on coefficient of determination, T-test, root mean square error (RMSE), Model efficiency (EF), mean bias error (MBE) and normalized root mean square error (NRMSE). The results showed that normalized root mean square error of the grain yield and biological yield were 9% and 5%, respectively. Based on the productivity and reduction in the yield of Rice, flooding Irrigation was the most efficient in April, 21th Planting date. According to the correlation coefficient upper than 0. 7 and Model efficiency upper than 0. 6, the AquaCrop model had a good accuracy in simulating grain yield and biological yield, therefore AquaCrop model can be used to support the results of experiments under Irrigation management conditions and different Planting dates.
