Acúmulo e qualidade da forragem Urochloa brizantha (hochst. ex a. rich.) stapf cv. xaraés com dois clones de eucalipto em sistema silvipastoril

Abstract

The experiment was conducted in two silvopastoral systems (SSP) with four years of age, with the componete the Eucalyptus tree urograndis (E. urophylla x E. grandis), Eucalyptus Grancam (Eucalyptus camaldulensis x Eucalyptus grandis) and Urochloa brizantha. Xaraés as forage component. The area is located in the Fazenda São Paulo, the city of Ivinhema- MS. The aim of this study was to evaluate the influence of different spacings of two eucalyptus clones in silvopastoral system. The experimental design was a randomized complete block in a split plot. The chemical analyzes were done twice a year (January and July). The shade provided by the eucalyptus trees, reduced the total dry mass production, but favored the increase in the contents of the variable crude protein (CP). Forage Urochloa brizantha Xaraés got ideal accumulation and nutrition for use in silvopastoral system. The production and grass quality is influenced by different spacings of Eucalyptus clones with dry mass increase with increased spacing.
