The aim of this study was to evaluate the forage accumulation during the stocking period on Kikuyu grass pastures ( Pennisetum clandestinum  Hochst. Ex. Chiov) subjected to intermittent stocking. Treatments consisted of four defoliation levels (removal of 40, 50, 60, and 70% relative to the initial height) starting from the same pre-grazing height (20 cm). The following variables were evaluated: leaf and stem elongation rates (evaluated during four times across the period of occupation), leaf area index, and forage accumulation rates. Additionally, ten tillers/strip were evaluated for the same variables into exclusion cages. The linear, quadratic and cubic effects of severity of defoliation were evaluated by orthogonal polynomials contrasts with 5% of significance level. There was a linear and inverse relationship between the proportion of removed leaf area index with leaf elongation and herbage accumulation rate. The leaf elongation rate in individual tillers and the forage accumulation rates of tillers on excluded areas from grazing were greater than those under grazing. During the stocking period on pastures submitted to intermittent grazing, forage accumulation was observed and it was linear and negatively correlated with the proportion of leaf area removed. Keywords:  accumulation rate; forage production; leaf area index; severity of defoliation; tissue turnover.
