A two-year field investigation was conducted to evaluate the response of two varieties of Guinea grass and two leguminous species, grown alone and in mixtures, to fertilizer treatments. Styloxanthes gracilis and a Guinea grass variety ‘Liconi’ were observed to be superior to others in their yielding ability. Styloxanthes and the Liconi Guinea grass appeared to be mutually compatible at particular seeding rates. Sabi Guinea grass and Centrosema pubescens were the poorest performers under all conditions. Findings also suggested that the adapted and mutually-compatible legumes and grasses could be grown in mixture under tropical conditions, and high yields obtained without the use of expensive nitrogenous fertilizers.
