Short summary
Using an advanced optimisation method, we calibrated a crop model against dry matter, carbon and water exchanges. Although model predictions matched observations well, the process revealed weaknesses in the model, such as difficulty in representing evapotranspiration, especially during heatwaves. This multi-objective approach highlighted the need to better capture stomatal and non-stomatal responses in order to improve predictions of crop models.
