Theme 22: Grazing Management
Description
The forage accumulation and floristic composition of native pasture, submitted to burning and alternative management practices, was evaluated during one year. The experimental design was a completely randomized, with five treatments and three replications. The forage accumulation was evaluated in a grazing exclusion cage, and the floristic composition was estimated with Botanal method. The systems without burning were more productive and, among these, the forage accumulation was similar between the one without burning and without mowing and the improve treatments, and the annual accumulation was greater than 9,000 Kg/ha of green forage dry matter. The species Paspalum notatum, P. paniculatum and Desmodium incanum had greater contribution in the improved and mowed treatments. The biennial burning stimulated species of Andropogon and Schizachyrium genus and also opportunistic species. The alternative management showed to be more sustainable, promoted greater floristic diversity, and allowed increase of species with good nutritive value.
