Manejo de pastagem anual de inverno em sistema integrado de produção agropecuária

Abstract

This study aimed to evaluate the impact of the Crop-Livestock Integration System (SIPA) on oat production in Aruana grass pasture in a specific region (Guarapuava/PR). Three production systems were compared: SIPAaruana, SIPA, and CA (Conventional Agriculture System). Autumn grazing on Aruana grass did not negatively affect the development of sown oats. There were no significant effects on height, population density of tillers, forage mass, and total dry matter productivity of winter oats. Total dry matter production (PROD.t) was significantly higher in the SIPA treatment, producing 4,251 kg more dry matter per hectare compared to the CA treatment. This highlights the importance of the animal component in increasing production and biomass. The SIPAaruana treatment had a similar daily live weight gain (GPVdia) to the SIPA treatment, despite a lower animal load and a shorter cultivation period for white oats. During the consortium period of Aruana grass with corn, the system offered direct and indirect benefits, allowing forage planning in autumn and contributing to oat cultivation. The use of SIPA with Aruana grass after corn harvest allowed for a longer grazing period compared to monoculture corn. The results suggest that the Crop-Livestock Integration System, especially when combined with Aruana grass cultivation, can be beneficial for oat production and animal performance. This results in increased biomass productivity and live weight gain per area.
