Abstract

This work was done during the period of October of 2002 to April of 2003 at Coronel Pacheco, MG, to evaluate the effects of two stubble heights (50 and 100 cm) post grazing and the tiller class (basal and aerial) on herbage mass and her morphological composition of elephantgrass (Pennisetum purpureum Schum.) cv. Napier pastures managed under grazing. A complete randomized block design in a split-plot arrangement and four replications per treatment was used. The herbage mass and their percentages of dead material, green leaves, decapitated stem, beyond leaf: stem ration of basal and aerial tillers were evaluated. Higher herbage mass were observed for 100 cm than 50 cm stubbles and for basal than aerial tillers. The pastures managed with 50 cm post grazing stubble height showed higher percentages of leaves, smaller of stem and higher leave: steam ration than that with 100 cm. The basal tillers showed higher percentages of decapitated stems and, the aerial tillers, higher leaf: stem ration during experimental period, beyond higher green leaves proportions than basal tillers during the summer season.
