Abstract
The ORYZA2000 model was tested in Iran for simulating the response of two rice genotypes to water management. Study was carried out in a Randomized Complete Block Design between 2012 and 2013, with 3 replications at Rice Research Institute of Iran, Rasht. Irrigation management (4 regimes) was the main plot and rice genotypes was the sup-plot. Evaluation simulated and measured final biomass and yield, by adjusted coefficient of correlation; T test of means; and by absolute and normalized root mean square errors (RMSE). Results show, with normalized root mean square errors (RMSEn) of 610%, ORYZA2000 satisfactorily simulated final biomass and yield. Grain yields and biomass of genotypes rice were adequately simulated by the model (differences between simulated values and observations were less than 10%).
