Abstract
Six factorial experiments, each lasting 3 years, were carried out to determine the effects of N, P and K on herbage cut five times each year. Clover almost disappeared with the 87 lb. N treatment and none survived with the 174and 348 lb. dressings. N increased the proportions of rye-grass and cocksfoot in the sward. P had no influence on botanical composition. K usually increased the clover content in the absence of, but had practically no effect in the presence of, N.
