with D. decumbens. In the average total yields, however, A. gayanus outyielded all its mixed stands. Pure stands of D. decumbens, C. pubescens and D. leiocarpum were all outyielded by their mixed stands in all the harvesting periods and in average total yields. All the yield differences between the pure and mixed stands were highly significant (P = 0,01).
Mixed stands The highest yielding mixed stand in the first harvest was DigitariajCentrosema; in the second harvest, it was AndropogonjCentrosema. But from the third to the fifth harvest, Andropogon/ Des- modium outyielded all the other mixed stands. In the average total yields, AndropogonjDes- modium outyielded the other mixed stands; it wa
