Summary: Mixed cropping peas with false flax, a brassica oil seed crop, in additive arrangements had a significant suppressive effect on weed coverage. Weed suppression was probably achieved by a mutually enhanced competitiveness of both crop components, indicating a mechanism based on resource allocation, but further research is needed for a better understanding of weed suppressive traits in pea–false flax mixed cropping systems.
