Conteúdo: | The reponse of Brachiaria decumbens cv. Australiana, B brizantha cv. Marandu, B humidicola, and Andropogon gayanus cv. Planaltina to five rates of phosphorus (0, 30, 60, 90, and 120 kg/ha of P O) was studied in an Allic red-yellow Latosol at the experiment station of the Centro de Pesquisa Agropecuaria do Meio-Norte of the Empresa Brasileira de Pesquisa Agropecuaria (EMBRAPA). The experiment station is located in Teresina, Piaui (5 5' S and 49 48' W, 72 m.a.s.l.), with an average temperature of 27.4 C and 1360 mm rainfall. A randomized split-plot design was used, the grasses composing the main plost and the P rates, the subplots. Four cuts were made during the dry season (every 8 weeks). The growth of B. humidicola was slow during the first year but then became highly productive. All grasses responded to P. maximum DM production during the dry season was obtained with the application of 90 kg/ha of P2O5 and, during the rainy season, with 68.8 kg/ha of P2O5.
