It was evaluated tiller appearance, mortality and survival rates, the flowering percentage and the population density of basal tillers in pasture of Brachiaria decumbens under four doses of nitrogen (75, 150, 225 and 300 kg/ha/year), in three periods of the year: February to April, May to August and September to November. The experiment was conducted in a completely randomized design with periods as a split plot feature, with two replications. The nitrogen fertilization was split in three applications the first […]

A study was conducted to evaluate three cultivars of Panicum maximum Jacq. under rotational grazing for the nutritive value,where the estimates of crude protein, neutral detergent fiber, acid detergent fiber, lignin, cellulose, silica, and in vitro digestibility of the organic material were performed in samples of leaves and stems. Additional nitrogen was applied in cv. Tanzania at the end of the rainny season. Samples were taken in June, September, and October 1998 and in March 1999. Some differences among treatments […]

It was studied five management systems of native pasture, under grazing, from Rio Grande do Sul State: with biennial burning for more than 100 years, without burning for 32 years with or without mowing, and pasture improvement for 7 and 24 years. The forage accumulation and the senescent material detached from the plant, were evaluated using grazing exclusion cage. The experimental design was a completely randomized with three replications. The systems without burning were more productive and among these the […]
