Avaliação de cultivares de aveia branca para produção de silagem

Abstract

This paper addresses the evaluation of the potential of oat cultivars for silage production. The cultivars were FUNDACEP FAPA 43, BRS Centaur, URS URS Guapa and Corona, being seeded 16 plots with 4 treatments, 4 replicates and experimental design Entirely Randomized. The silages were prepared at the phenological stage of dough grain and wrapped in experimental silos were opened after 90 days of fermentation. The variables studied were forage production of green mass, dry matter percentage of pre, dry matter forage production, percentage of leaf, stem, dead material, grain, dry matter recovery, silo density, dry matter silage production silage, fermentation parameters and characteristics of silage losses. As a result, the cultivar earlier for the production of silage was URS Guapa. Most silage production was observed for the cultivar URS Corona. The recovery of MS was similar among cultivars. Thus, it is concluded that the plant variety that features more balanced outcome between cycle, forage production and fermentation characteristics is the URS Corona, the most suitable for silage production in the region of the Rio Grande do Sul missions.
