Abstract

When 6 perennial ryegrass cv. were planted in sandy soil in a large tray with couchgrass [Elymus repens], the cv. which developed the greater root system were the most competitive. Perennial ryegrass cv. 39 gave low DM yields in monoculture but was the most competitive with couchgrass. There was an inverse relationship between root mass of perennial ryegrass in monoculture and the herbage yield of couchgrass in the mixture.
