XAVIER, Deise Ferreira et al. Effect of the post-planting management on the establishment of elephantgrass pastures. Rev. Bras. Zootec. [online]. 2001, vol.30, n.4, pp.1200-1203. ISSN 1516-3598.  https://doi.org/10.1590/S1516-35982001000500010.

A good establishment is an important condition to obtain adequate levels of productivity in elephantgrass pastures. However, besides the adoption of good agronomic practices at planting, it is necessary to assure that the post-planting management is correct, to favor the future productivity and persistence of the pasture. Aiming at obtaining a good initial density of elephant-grass in the pastures, various post-planting management systems were studied. The following treatments were compared: grazing three months after planting, followed by cutting at 20 cm height from ground level (P20-3), at 40 cm (P40-3) and at 80 cm (P80-3); cutting three months after planting, at 20 cm from ground level (C20-3) and cutting four months after planting at 20 cm from ground level (C20-4). The experiment was undertaken in Coronel Pacheco, MG, in a red-yellow latosol. Experimental design was randomized blocks with four replications, and plots measured 8 x 10 meters. Forage availability, number of plants per hectare and percentage soil cover did not differ among treatments. The cutting at 20 cm height from ground level, three months after planting did not contribute to increase plant density or forage dry matter yield. Basal tillering was not affected by treatments. It was concluded that elephant-grass pastures can be grazed three months after planting, without reducing its productivity thereafter.
