Conteúdo: | Abstract The aim of this work was to evaluate the biomass productivity and chemical-bromatological quality of Urochloa brizantha cv. Marandu, intercropped with diferent leguminous under organic management. The experiment was conducted for 3 years at Brazilian Agricultural Research Corporation ? Embrapa Cerrados in Planaltina ? DF, Brazil. Two independent experiments were designed. The frst one with a previous green manure crop and the second, without green manure crop. After that, were planted in both experimental areas the Urochloa brizantha cv. Marandu intercropped with Stylosanthes spp. The experimental design was performed in randomized blocks, in the sub-subdivided plot scheme with 3 replicates and 3 factors. Forage mass production, nutritional value, and protein and carbohydrate fractionation were evaluated in trials. Urochloa presented better quality in the organic system, with the lower lignin content (3.9%) and the reduction of low availability nitrogenous compounds. Stylosanthes spp. presented better chemical-bromatological quality with green fertilization in the form of organic fertilization, due to the signifcant reduction of fbers and lignin, a result that promoted improvements in digestibility. Both Urochloa and Stylosanthes presented better nutritional quality in the system with green fertilization and organic form of fertilization.
