Abstract: Two approaches of modelling competitive interactions are discussed: a regression approach and an eco-physiological approach.In the regression model, the relationship between yield and plant density of the different species in the mixed stand is described by an empirical regression equation.In the eco-physiological model, the competition process itself is • described in due time on the basis of the underlying processes of resource acquisition and utilization.The regression model can be used as a simple procedure to analyse intercropping experiments, especially in trials with•• only a final harvest.The regression model and a simple version of the eco-physiological model seem tq be the most appropriate types of model for assessing optimum intercropping combinations.However, for understanding of the competitive ; interactions, the dynamic eco-physiological approach is indispensable.
