Yields and Changes of Botanical Composition in Several Pure and Mixed Pastures Grown under Different Fertilizer Conditions in Thailand

Abstract

Yields and changes of botanical composition in several pure and mixed pastures in Thailand were investigated. The yield in these regions were comparatively low owing to a shortage of water and nutrients. Rhodesgrass seemed suitable for keeping a good ratio of legume, but allowed the invasion by weed. Glycine did not seem suitable for the mixture with grasses. Application of high levels of fertilizers decreased the ratio of glycine.
