Abstract

The SIMULATION MODELs of yield response to water are expected to play an increasingly important role in the optimization of WATER PRODUCTIVITY (WP) in agriculture. In this study, the CERES-Wheat model was used to simulate of WHEAT YIELD response under different irrigation-cultivar treatments with three irrigation treatments in main plots and Five wheat cultivars in sub plots consisted of C1:C-75-5, C2: C-78-4, C3:C-78-8, C4: C-79-6 and C5: C-79-16 in Mashhad region during the years of 2002-2003 and 2003-2004. According to the results, the relative root mean square error of grain yield simulation by CERES-Wheat model was 7 and 10 % for 2002-2003 and 2003-2004 years, respectively. Because the relative root mean square error was less than 10 percent, so done well simulation. Also, the root mean square error calculated for grain yield for both years was less than 10 percent of the observed mean. The results are indicating a good match to the simulation results of the model. The value WATER PRODUCTIVITY based on crop evapotranspiration and irrigation water value in I3-C-79-6 treatment has the value highest for both years of 2002-2003 and 2003-2004. Therefore, the noted IRRIGATION MANAGEMENT (I3) and wheat cultivar (C-79-6) can be recommended in the study area. The overall findings of this study to confirm the optimal performance of the model CERES-Wheat in the growth process simulation and the water impact on yield in the study area.
