The objective of this work was to evaluate the structural characteristics and herbage accumulation of Tanzania grass pastures (Panicum maximum cv. Tanzania) under rotationally grazing, in an Oxisol, in experiment carried out at Campo Grande, MS. Treatments corresponded to combinations of three pre and two post-grazing conditions, and were allocated to experimental units according to a complete randomized block design, with three replications and a 3x2 factorial arrangement. The pre-grazing conditions of 90, 95 and 100% light interception (LI) were achieved consistently with swards heights around 60, 70 and 85 cm, respectively. Grazings at 90% LI resulted in larger number of grazing cycles than grazings at 95 and 100% LI. Total herbage accumulation was larger with grazings at 95% than at 90 and 100% LI, but there was no difference between the 90 and 95% LI treatments for leaf accumulation. Accumulation of stem material increased substantially after 95% LI, indicating the importance of grazing frequency as a means of controlling sward structure and composition.
