The dry matter yield, crude protein content and botanical composition of pastures of Pennisetum purpureum (Napier), Panicum maximum (Guinea B) and Brachiaria brizantha grown pure and in combination with Pueraria phaseoloides, Centrosema pubescens and two cultivars (Schofield and Fine Stem Oxley) of Stylosanthes guianesis were studied. The dry matter and the crude protein yields for the 3 grasses when grown alone were comparable. The legume component dry matter yields were highest for Schofield Stylo, and both Stylo cultivars outyielded Pureo and Centro in the mixtures. Napier Stylo mixtures were the most productive. Because of t1437he higher legume content, the total crude protein yields were higher in the Stylo associations than in the other associations or pure grasses. Brachiaria combined poorest with legumes. Weed growth was least in the Brachiaria pastures. The results vindicate the advantages of legume based pastures over nitrogen fertilized pure grasses of comparable y
