Perennial ryegrass is a high yielding, high quality grass. The best varieties are very persistent under a grazing management, provided they are well fertilised, well managed and the winters are not too severe.
In cold areas perennial ryegrass plays an important role in short term leys with high yields and quality. Perennial ryegrass is compatible in mixtures with white clover.
It is suitable for cultivation in most types of soils except very wet land. Perennial ryegrass is available in early, intermediate and late heading types and in diploid and tetraploid forms.
