Evaluation of pasture recovery methods pastures of Brachiaria at the agreste region of Pernambuco state: 2. nutritive value of forage
[摘要]

The research was carried out to evaluate qualitativeaspects of a B. humidicola degraded pasture managed under different recoverymethods in Bezerros-PE. A confounded split-plot randomized block design wasused. The main plot was formed by the factorial arrangement between managementsand fertilization levels. The splitplot model consisted of the different defermentperiods. The factors were represented by four recovery managements (no-tillage,arrowing, arrowing + corn, no-tillage + corn), two N levels (0 and 100 kg/haof N), two P levels (0 and 100 kg/ha of P2O5) and fourdeferment periods (113, 156, 200 and 240 days), with three replications. CP,NDF, ADF, P, ashes contents and IVDMD were determined. Significant interactionamong management systems and P fertilization was observed when NDF, ADF andP concentration of braquiária were evaluated. B. humidicola defferedfor 113, 156, 200 and 240 days showed the following ADF and IVDMD values, respectively:40.36 and 61.92%; 43.89 and 56.58%; 44.52 and 31.35%; 46.25 and 30.07%.
