摘要：

This work used the necessary time (days) for a completely elongation of new leaves, i.e., 1.5-2.0; 2.5-3.0 and 3.5-4.0 new leaves completely elongated in order to determine the rest period ( RP) between grazing in Pearl millet (Pennisetum glaucum (L.) R. Br.). The experiment was carried out as a completely randomized design with four replications (paddocks). Evaluations were performed for: number of live leaves/tiller (NAL); final length blade (FLB); blade/sheath and culm ratio (B/S+C); basal tiller density (BTD) and aerial tiller density (ATD). The higher BTD; NAL and B/S+C ratio observed in the shortest rest period determined the high quantity of green blades in the pasture sward and consequently the best structural characteristics from the forage point of view.
