ABSTRACT
Crop models bring together the knowledge obtained on a species for a specific use, and therefore are useful for identifying gaps in our knowledge of the physiology of the species concerned. They may be used to simulate the behaviour of crops grown without any limiting factors in order to make an agronomic diagnosis at the plot scale. In this case, the objective is to answer questions such as: what was the yield potential of the plot allowed by the climate? Did some factors limit the yield? Which ones? When did they affect the crop?
