Description
Competition is a major cause of changes in the botanical composition and yield of pastures. Species that are compatible with each other do not utilise the same resources at the same time and therefore suffer less competition. Selecting compatible species in a mixture could thus enhance the yield and stability of the sward. The objective of this experiment was to compare the yield and botanical composition of a range of pasture species sown in simple or complex mixtures. Complex mixtures of more than 2 species tended lo outyield simple mixtures, and swards with perennial ryegrass (Lolium perenne) tended to perform better and persist better. Both red clover (Trifolium pratense) and white clover (T. repens) contributed significantly to the sward. Three pasture grasses, viz., perennial ryegrass, cocksfoot (Dactylis glomerata) and red fescue (Fesitca rubra), were identified as suitable for sowing in Weining.
