Intercrop module for the STICS simulation module

The development of the STICS simulation model intercrop module model through the extrapolation of the sole crop model and the parameterisation from experimental data recorded in sole crops allows an accurate simulation of the interactions for resources between intercropped species. The simulated responses of the intercrops are in agreement with the observations from the experimental datasets. The STICS model seems to be an operational tool for simulating growth and N accumulation in pea-barley intercrops and for predicting the composition of the final mixture according to soil N supply.

However the experiments used for the parameterization in sole crops and the validation in intercrops were not independent and were carried out with only one limiting factor (nitrogen). This model needs to be tested under a wider range of situations and in the case of other limiting factors occurring in low-input farming systems. The model is useful for testing technical strategies. Strategies to get the best agricultural results can be different according to locations and output objectives: favouring pea or barley, grain or forage utilization.
