The objective of this study was to evaluate the effects of pearl millet (Pennisetum glaucum (L.) R. Br) seeding rates (0, 5, 10, and 15 kg ha−1) in association with palisade (Urochloa brizantha (Hochst. ex A. Rich.) R.D. Webster cv. Marandu) and gamba (Andropogon gayanus Kunthvar. Bisquamulatus (Hochst.) Hack. cv. Planaltina) grasses on establishment parameters and forage biomass (FB) yield under low-input systems in Brazilian Cerrados. The experiment was conducted from December 2009 to April 2010, in Barreiras, Bahia, Brazil, using plots of 20m2 (5 × 4m) under a randomized complete block design with four replications. The number of perennial grasses (NG) and millet (NM) seedlings were counted at 7th, 14th, 21st, and 28th day after sowing (DAS). The heights of perennial grasses (HG) and millet (HM) were measured at 48th, 73rd, 98th, and 125th DAS. On these dates, DM yield was quantified by harvesting the whole forage above 30cm. The increase in pearl millet seeding rate reduced NG and HG, while NM and HM increased. Association of pearl millet with grasses increased DM yield quadratically, with maximum point at the seeding rate of 6.5 kg.ha−1. The presence of pearl millet affects the establishment and DM yield of palisade and gamba grasses, being recommended henceforth for reducing the first grazing event.
