A. gayanus outyielded all the pure stands in five harvesting periods. D. decumbens produced the second highest yields in all the five harvests. Thus the pure stands of the two grasses outyielded those of the two legumes. Between the legumes, C. pubescens outyielded the D. leiocarpum in the first and second harvesting periods only; but was outyielded by the latter from the third to the fifth harvests.
