he Effect of Cutting Frequency on the Persistence and Dry Matter Yield of Some Grasses and Legumes Seeded Alone or in a Complex Pasture Mixture

الملخص

1.There was no observable advantage of the complex pasture mixture ever the high yielding pure species for dry matter production.
2.Out of the 11 species included in the complex pasture mixture, only perennial ryegrass, tall fescue, orchardgrass and a small percentage of smooth bromegrass and legumes were established. Following the first harvest, ryegrass which comprised 50% of the original stand was largely replaced by other grasses.
3.Orchard grass, perennial ryegrass and tall fescue were more aggressive than smooth bromegrass in the complex mixture but were not high yielders in pure stands.
4.Kentucky bluegrass, redtop, Poa trivialis and perennial ryegrass were lower yielding in pure stands.
