“…Panicum maximum Jacq.) have been showing outstanding agronomic and nutritional traits to be incorporated into beef cattle systems when grazing systems are satisfactorily managed and fertilized Pinheiro et al, 2015). The fertilization of grass pastures, especially with nitrogen incorporation, plays an essential role for the productive system, since, when there is no restriction of other nutrients, N is the greatest contributor to productivity enhancement (Euclides et al, 2007).…”

-The objective of this work was to evaluate the physical properties of a soil with a 'Tanzânia' grass (Megathyrsus maximus) pasture fertilized with mineral nitrogen or intercropped with the legume 'Campo Grande' (Stylosanthes spp.), and subjected to continuous grazing and variable stocking rate, in a three-year chronosequence. The treatments were: 'Tanzânia' grass and Stylosanthes; and 'Tanzânia' grass fertilized with 75, 150, and 225 kg ha -1 N per year. The experiment was carried out in an Oxisol, in a randomized complete block design with three replicates, in split plots divided according to time (first, second, and third experimental years). The following soil properties were assessed annually: soil bulk density, porosity in the soil macropore domain, soil water and air storage capacity, and soil penetration resistance. After three years, the highest animal stocking rate due to increased forage yield did not affect the soil physical conditions. The intercrop of 'Tanzânia' grass with the legume shows values of soil water and air storage capacity close to the ideal ones (0.66 and 0.34, respectively). After the second experimental year, there is a decrease in the penetration resistance values, which are inferior to the critical limit of 2,500 kPa. The intercropping of 'Tanzânia' grass with stylosanthes 'Campo Grande' can be a remarkable alternative for the maintenance and improvement of soil physical conditions.

The objective of this work was to evaluate the supply, morphological and chemical composition of forage, performance and milk composition of crossbred cows managed in Megathyrsus maximus cv. Tanzania in intermittent grazing system with fixed and variable defoliation intervals according to the interception of 95% of photosynthetically active radiation by the canopy. The experimental design was a randomized complete block design with two treatments and two area replications. In each grazing cycle the supply, morphological composition, forage nutritive value, dry matter intake, milk production and composition were determined. The experimental area was 4.0 hectares, divided into two blocks of 2 hectares. Each block was subdivided into 22 pickets (11 for each treatment) totaling 44 pickets with an area of 909 m2 each. Significant differences (P < 0.05) were observed for leaf blade content, in vitro digestibility of dry matter and forage crude protein, dry matter intake, individual and area milk production and lactose content milk, being the highest values found in the pastures managed with variable defoliation interval. Thus, the defoliation interval defined by the 95% interception of the photosynthetically luminosity leads to higher leaf blade proportions in the forage canopy, resulting in higher individual milk yield and per unit area, but with a loss of protein and total solids contents of milk.
