Comparison between observed yield data and simulations, with inputs from different combinations of a general plant parameter (RUE, radiation use efficiency) and STICS built-in cultivar choice (No.1 to No.9). The following evaluation metrics are considered: a nRMSE (normalized root mean square error), b MAE (mean absolute error), and c correlation coefficient (r), together with d the results from the selected combination of RUE (approximation of 2.75 to 2.8 g MJ−1 day−1) and cultivar choice (cultivar No.7–Thetalent). Refer to online resource 2 for summarized input parameters used for calibration
