Fig. 1: Crop model calibration on the field scale.
From: Breeding changes water use of winter wheat across Europe
Crop model calibration results of the calibration of above ground dry matter biomass (t ha−1; a, d), leaf area index (b, e) and canopy transpiration rates (mm day−1; c, f) of the winter wheat cultivars Tommi (released 2002, a–c) and S. Dickkopf (released 1895, d–f). Lines indicate model simulation results, points indicate mean observations of the respective outputs with standard deviations (see Table S1 for number of measurements of each variable), measured in the year 2024. Metrics of model fit presented are root mean square error (RMSE), relative root mean square error (rRMSE), Willmott’s index of agreement (d-Index), mean absolute Error (MAE).
