Abstract: The main objective of this study was calibration and testing of crop growth model \nHERMES2Go under long–term field experiment in Hněvčeves locality (coordinate 50°18´N, 15°43´E, \naltitude 265 m.a.s.l.). Observed data of yields and the other parameters like a weather data, soil \nparameters, management practice, phenology phases etc. monitored in last 38 years was used for model \ncalibration. Input parameters were available for 4 different fertilizer practices: i) control, ii) manure, iii) \nmineral fertilizer and iv) manure together with mineral fertilizer on each plot. Observed data are \navailable for yields of main and by–product and above ground biomass. The main grown crops were \nsugar beet, spring barley, winter wheat, silage maize, oat and alfalfa. Outputs of the model for main \nproduct are relatively accurate, but values of by–product requires additional calibration parameters \nsettings together with above–ground biomass.
