The objectives of this study were to (1) determine the critical threshold diffuse knapweed density at which crop loss is significant for four forage species; (2) to produce a predictive model for the loss in forage for a given density of knapweed; (3) to determine how subsequent years of interference affect the relationship between knapweed density and forage yield; and, (4) to determine which grasses are most competitive with knapweed.
