The aim of this study was to evaluate the effects of shading on structural characteristics and herbageaccumulation of palisade grass (Brachiaria brizantha cv. Piatã), in a crop?livestock?forest integration area. Three shaderegimes were evaluated: no shade (NS), moderate shade (MS, 338 trees ha?1), and intense shade (IS, 714 trees ha?1). Theeffects of shade regime on soil-water content and nitrogen nutrition index were also evaluated. Grazing management wasestablished based on sward light interception targets (95% LI pre-gazing). The MS and IS regimes were divided into twoshade strips (central and lateral) in order to describe the variation in light availability within the paddocks. Two methodsfor taking the reference readings of LI were tested in IS paddocks: LI reading inside (under the tree canopy) and outside(under full sunlight) the experimental area. Increased tree density reduced photosynthetically active radiation on lateral andcentral shade strips by 37% and 12% for MS, and 52% and 50% for IS, respectively. For NS, MS, IS (outside) and IS (inside),grazing intervals were 23, 26, 28 and 35 days, pre-grazing heights corresponded to 33, 35, 43 and 52 cm, and pre-grazingherbage mass to 5.37, 4.44, 2.96 and 3.23 t ha?1, respectively. Leaf percentage remained relatively stable across shaderegimes, but stem percentage was greater and dead material percentage was smaller for IS than for NS and MS. Soilwater content was lower near the trees, especially during the dry season. Relative to NS, herbage accumulation decreasedby 39% and 68% for MS and IS, respectively. Under natural shade, small variations in light availability affect swardstructure and herbage production. The use of the 95% LI target developed under full sunlight conditions is not suitable foruse under trees, emphasising the need to generate specific grazing-management targets for pastures cultivated under trees.
