Abstract: An experiment was carried out in order to evaluate the effect of shading on the physiology and canopy structural characteristics of tropical grasses under different woody covers in silvopastoral system in the semiarid region of Brazil, in a region known as the Caatinga biome. The experimental area had nine silvopastoral systems arranged in strips of Caatinga vegetation trees (woody component) with dimensions of 6.0?×?100.0 m, positioned in the north?south direction. Among the strips of Caatinga trees, Urochloa mosambicensis, Pennisetum ciliare and Megathyrsus maximus were planted in plots. The treatments were: forage grown under 46.15% of woody cover (SS46), forage grown under 30.00% of woody cover (SS30) and forage grown under 17.64% of woody cover (SS18), each with three replicates. The gas exchange assessments were carried out in 2018 and 2019 for two consecutive days. Structural and production characteristics were evaluated in 2018 and 2019, considering the east, center and west positions. The system SS46 promoted lesser leaf photosynthesis among Pennisetum ciliare and Urochloa mosambicensis. SS46 favored lower tiller population density on grasses. Total forage biomass was lower in SS46 in comparison to SS30 and SS18. Silvopastoral systems SS30 and SS18 can be adopted without compromising the physiological characteristics of Urochloa mosambicensis and Pennisetum ciliare, and the structural and yield characteristics of Urochloa mosambicensis, Megathyrsus maximus and Pennisetum ciliare.
