Calibration of the crop growth models for winter wheat

Popis výsledku v původním jazyce

Calibration of the crop growth models DAISY and HERMES was based on experimental results from the Experimental station in Domanínek. Crop parameters of winter wheat, represented by cultivars Etela and Bohe mia, were calibrated. Experimental data (included observations within field trials with two different sowing dates and two nitrogen fertilization levels) from the year 2012 were used for calibration. Evaluation of agreement between simulated and observed d ata was done using selected statistical indicators, e.g. the root mean square error (RMSE) as a parameter of average magnitude of error and t he mean bias error (MBE) as an indicator of systematic error. Namely measured and simulated leaf area development, phenological phases, soil moisture contentand yields were compared. According to the statistical parameter MBE the average simulated flowering by DAISY fit the mean observations and it was slightly underestimated by 0.5 days using HERMES. Also maturity wa s estimated very slight
