摘要: The objective of this study was the evaluation CERES rice model under different nitrogen- and water-management conditions in northern Iran. A 3-year field experiment conducted at experimental farm Iranian Rice Research Institute Rasht, Iran, from 2005 to 2007. established a split-plot design with three irrigation regimes (continuous submergence, 5-day intervals, 8-day intervals) as main plot, four nitrogen levels (0, 45, 60, 75 kg N ha−1) subplot, replications. Evaluation simulated measured grain yield, total crop biomass, content grain, biomass by adjusted coefficient correlation absolute normalized root mean square errors (RMSE). Results showed that predicted yields agreed well observed (RMSEa = 297 RMSEn 8%). Simulated dry-matter were also reasonable agreement (RMSEn 862 10%). Observed u...
