| Abstract: | Summary. In a field experiment with different densities of Alopecurus myosuroides , 10 plants/m2 caused no significant reduction in total dry weight of winter wheat at harvest. When autumn- or spring-germinated plants at 100/m2 remained until harvest, crop weight was reduced by about 30%. A study of root-zone competition between A. myosuroides and winter wheat in the glasshouse showed that suppression of the weed by the crop was greater at high nitrogen levels; the practical implications of this are discussed.
