Summary: The tolerance to the shade is the first characteristic to be observed in the choice of forage to form an integrated system with trees. This work aimed to evaluate the production and quality of forage in the establishment of Ipyporã grass in silvopastoral systems in southern Amazon. The experiment was carried out at Embrapa Agrossilvipastoril - MT - Brazil. Five treatments were evaluated: without trees; double rows eucalyptus in a density of 260 trees ha-1; triple rows of 340 trees ha-1; double rows in a density of 130 trees ha-1; simple rows with a density of 120 trees ha-1. In the Ipyporã grass formed under the treatments was evaluated the herbage, leaf, stem, and dead material mass, leaf protein, crude protein, NDF, ADF, canopy height, and volumetric density. The integrated system with the highest density of trees decreased the herbage and leaf mass, and increased the content of protein in the leaves. Crude protein, ADF, height, and leaf volumetric density were somewhat affected by the shade in the integrated systems and not only the tree density seemed to influence on them, but also the tree arrangement. Thus, tree density and arrangements should be carefully planned to better establishment of pasture in integrated systems.
