Evaluation of Yield Prediction Performance of DSSAT CSM-CERES-Wheat Model in Some Bread Wheat Varieties

Product simulation programs with DSSAT are based on the principle of predicting potentials yield and other phenological parameters wheat varieties different fertilizer application doses in climatic soil conditions. For this purpose, (Bayraktar, Tosunbey) were used order to test use model semi-arid conditions Ikizce experimental area Haymana District Ankara Province, Field Crops Central Research Institute, during 2017-2018 2018-2019 periods. The aim study is predict using CERES CROPGRO sub-models v.4.7.5 model. In study, was run at nitrogen (0, 6, 12, 18 kg/da) reveal prediction potential cultivars calibration model, grain yield, plant height Leaf index (LAI) data obtained first year development stage.The accuracy which calibrated data, tested second data. Bayraktar variety, average measured from dose applications (N0,N6,N18) for period 373.3 kg/da, simulated 373.7 kg/da (N12 neglected), 300. 5 found be 291.3 kg/da.For Tosunbey 370.0 338.0 217.58 estimated 237.83 kg/da.
