Avaliação de Métodos para Recuperação de Pastagens de Braquiária no Agreste de Pernambuco. 2. Valor Nutritivo da Forragem
The research was carried out to evaluate qualitative aspects of a B. humidicola degraded pasture managed under different recovery methods in Bezerros-PE. A confounded split-plot randomized block design was used. The main plot was formed by the factorial arrangement between managements and fertilization levels. The splitplot model consisted of the different deferment periods. The factors were represented by four recovery managements (no-tillage, arrowing, arrowing + corn, no-tillage + corn), two N levels (0 and 100 kg/ha of N), two P levels (0 and 100 kg/ha of P2O5) and four deferment periods (113, 156, 200 and 240 days), with three replications. CP, NDF, ADF, P, ashes contents and IVDMD were determined. Significant interaction among management systems and P fertilization was observed when NDF, ADF and P concentration of braquiaria were evaluated. B. humidicola deffered for 113, 156, 200 and 240 days showed the following ADF and lVDMD values, respectively: 40.36 and 61.92%; 43.89 and 56.58%; 44.52 and 31.35%; 46.25 and 30.07%.
