Three pot experiments are described in which perennial ryegrass (S23) and Plantago lanceolata (ribgrass) were grown alone and in mixed stands at varying densities and cent at different frequencies. With frequent cutting the yield of ryegrass was reduced to a greater extent than that of rihgrass, but the mean plant weights of both species were independent of sowing density. The pattern of competition was not altered by a single cutting treatment, the balance being quickly restored by the rapid regrowth of the ryegrass.
