Silvopastoral system implementation in Uruchloa brizantha pasture under continuous cattle grazing

Abstract: Silvopastoral is a sustainable integration system of tree component and animal in the same area, aiding soil fertility and promoting animal comfort. The objective was to evaluate different planting systems of forest component, at restoration time of Brachiaria brizanta cv. Marandu (Urochloa brizantha) pastures, under continuous cattle grazing. Eucalyptus (Corymbia citriodora) was planted in four arrangements (tree dispositions) with 1, 3, 5 and 9 seedlings, with three entry times of animals, 1, 30 and 60 days after planting the trees. Probability of survival of seedlings per arrangement and probability of survival of at least one seedling per arrangement with the presence of animals for 60 days, under continuous grazing, were evaluated. Probability of survival of at least one tree per arrangement regardless of disposition was higher at entry times 30 and 60 days. Arrangements 3, 5, and 9, there was a greater probability of a live tree than in arrangement 1. The results showed that it is possible to implement the silvopastoral system at the same time as pasture restoration, being more viable the entry of animals from 30 days after planting the seedlings, with greater probability of tree survival with more seedlings per arrangement.
