Abstract

MOOJEN, EDUARDO LONDERO; RESTLE, JOÃO; LUPATINI, GELCI CARLOS  and  MORAES, ADAUTO GOMES DE. ANIMAL PRODUCTION IN PEARL MILLET PASTURE UNDER DIFFERENT NITROGEN LEVELS. Pesq. agropec. bras. [online]. 1999, vol.34, n.11, pp. 2145-2149. ISSN 1678-3921.  http://dx.doi.org/10.1590/S0100-204X1999001100022.

An experiment was conducted at the Universidade Federal de Santa Maria, in Santa Maria, RS, Brazil, with the objective of evaluating the effects of three N levels (0, 150 and 300 kg/ha), in pearl millet (Pennisetum americanum (L.) Leeke) cv. Comum, on animal production. Beef steers were assayed through daily liveweigh gain, gain per hectare and animals.day/hectare. A continuous grazing system was used, with stocking rate adjustments to maintain a 10% grazing pressure that characterized a medium residue of 3,168 kg of DM/ha. The dependent variables showed a positive linear relationship with the N levels, denoting the high animal production potential of pearl millet.

Keywords : nitrogen fertilization; carrying capacity; animal performance; beef steers; animal productivity; urea.
