Abstract:
Due to the macroeconomic changes occurred in the modern agricultural scenario, it requires producers to promote intensification of production in pursuit of higher productivity and to address ecological issues that aim for the discussed sustainability. Thus, the Brazilian livestock chain needs constant updating in order to adapt to market requirements. Grazing is still the most widely used, viable and inexpensive technique, however, it's necessary to use technologies to reduce pasture degradation and seasonality in forage production and especially in the loss of nutritional value. The introduction of intercropping pastures comes in this context as an alternative to increase forage production and still improve its quality. Thus, the goal was to determine the dry mass production, tillering dynamics and chemical-bromatological composition of Xaraés grass pasture intercropped with Mineirão styles. The experiment was conducted at the Regional Jataí of the Federal University of Goiás - Jataí Regional, in a randomized block design with three replications, in a 5 X 2 factorial (5 doses of P: 0, 25, 50, 100 and 200 kg/ha and 2 capacity: 3 and 5 UA/ha). The evaluations were performed before and after grazing. Data were analyzed using SAS version 9.3 software at 5% probability. In conclusion, the P present in the soil was sufficient to supply the need of the intercropping species, that the phosphorus doses didn't influence the forage composition produced and that the lower stocking rate resulted in lower meristem decapitation and tillers mortality.
