註釋The competitive ability of celery was significantly higher than that of leek, owing to a more effective light interception. Therefore, the weed suppression of the intercropping system was considerably improved compared to the leek monoculture, resulting in a shorter critical period for weed control. The reproductive capacity of late-emerging S. vulgaris was strongly reduced in the intercropping system. Modelling studies confirmed the relatively greater competitive strength of celery compared to leek. Quantitative analysis showed that particularly differences in morphological characteristics, such as the early leaf area development, determined the differences in competitive ability between the crops. Further exploration and optimisation with a combined modelling approach allowed the design of a highly productive and profitable intercropping systems with improved weed suppressive ability.
