Several tropical grasses (Acroceras macrum, Cenchrus ciliaris, Cyndon sp., Digitaria sp. and Pennisetum clandestinum) and legumes (Desmodium uncinatum and Lotononis bainesii) were evaluated at the Kokstad Research Station (Bioclimatic sub?region 4f of Natal) over a period of seven years. The experiment was repeated on two soil types, a deep Doveton and a shallow Newport/Mispah transition. The yield data were subjected to a multiple regression analysis to assess the influence on yield of factors such as age of pasture, soil type, cutting frequency, N level, rainfall and temperature. The regression models are given and their implications discussed. Seasonal distribution curves using the Richard's function were developed for all species.
