ESTUDO DE CASO: PRODUTIVIDADE E QUALIDADE DE SILAGEM DE GIRASSOL CONSORCIADA COM CAPIM ‘BRS QUÊNIA’

Abstract

Preserving food for use during the dry season is essential for ruminant producers, so new ways of producing quality forage at lower production costs are constantly sought. Therefore, the productivity and quality of grass, sunflower and intercropped silage were evaluated. The experiment was carried out on the school farm of the Instituto Federal Goiano, Campus Iporá, in a soil classified as Cambissolo Háplico, where sunflower (Helianthus annuus cv. 'Altis 99') and grass (Megathyrsus maximus cv. 'BRS Qenya') were evaluated, which were sown simultaneously. The sowing density was 76 thousand seeds and 5 kg of seeds per hectare of SPV (Pure Viable Seed) of sunflower and grass, respectively. We observed that as the contribution to sunflower biomass productivity increases there is a tendency to reduce grass biomass, in the opposite direction, there is similar behavior, although with less intensity, we also observe that the biomass produced by the intercropped provides nutritional balance by adjusting the fat content of sunflower silage. Sunflower and grass complement each other, and the intercropped provides good quality silage.
