However, it’s necessary to know how forage species respond to the shading of these systems. The objective of this work was to evaluate the forage production potential and nutritive value of Panicum maximum cultivars for use in integrated crop-livestock (ICL) and integrated crop-livestock-forest (ICLF) systems, in the initial phase after establishment. A randomized block design with split-plots and two replications was used. The treatment of the plot consisted of systems (ICL and ICLF), the subplot, the Panicum maximum cultivars (BRS Quênia, BRS Tamani and Massai), the subsubplot, post-cut residue height (30 and 40 cm), and, the sub-subsubplot, seasons of the year (autumn, winter, spring and summer). Shading after one year of grass establishing in integrated systems does not affect the forage production and leaf crude protein content of P. maximum cultivars. The BRS Quênia and Massai cultivars have high production of total dry biomass. In summer, soil coverage by forage is greater than in other seasons, and cultivars at 30 cm residue height produce more total dry biomass than at 40 cm. The cultivars have better leaf crude protein content during spring.  aAgricultural land  aCultivars  aForage production  aShade  aSilvopastoral systems  aPanicum Maximum  aPlanta Forrageira  aVariedade1 aDELMONDES, T.
