dc.descriptionOur aim was to evaluate agronomic and chemical characteristics of corn hybrids to ensiling. It were evaluated nine corn hybrids (MX 300, RB 9308, 2B655, XB 6012, GNZ 2500, PL6890, PRE 32D10, PRE 22T10 e AG 1051), with three replicates. The higher fresh matter yield were observed in the hybrids PL6890 and PRE 32D10, while the dry matter yield was observed in the hybrid PRE 32D10 (13.43 t ha(-1)). The hybrids PRE 32D10 and PRE 22T10 stood out to present higher percent of leaf in relation to whole plant, while the lower percent of stems was found in the hybrids MX 300, 2B655 and XB 6012, however the higher leaves: stems relation was found in XB 6012 (0.49). There was higher CP content in the hybrid PRE 32D10 (9.10% of DM), while the lower NDF (57.78% of DM) and cellulose content (24.27% of DM) were observed in the hybrid GNZ 2500. The hybrid PL6890 presented higher ADF and lignin contents, the others hybrids had values lower. The lower NDIN content was observed in the hybrid RB 9308, while the lower AIDN content occurred on the hybrid 2B655. The lower buffer capacity was observed in the hybrid 2B655 (0.29). There are some differences on chemical composition among the corn hybrids used in this study, however, it is recommended to use the hybrids MX 300, PL6890 and PRE 32D10 for showing higher dry matter yield, which may reflect in the amortization of silage production costs.

dc.descriptionObjetivou-se avaliar as características agronômicas e químico-bromatológicas de híbridos de milho para ensilagem. Os tratamentos avaliados foram nove híbridos de milho (MX 300, RB 9308, 2B655, XB 6012, GNZ 2500, PL6890, PRE 32D10, PRE 22T10 e AG 1051), com três repetições. As maiores produções de MV foram verificadas nos híbridos PL6890 e PRE 32D10, enquanto a maior produção de MS foi observada no híbrido PRE 32D10 (13,43 t ha-1). Os híbridos PRE 32D10 e PRE 22T10 destacaram-se por apresentarem maior porcentagem de lâminas foliares em relação à planta inteira, enquanto a menor porcentagem de colmos foi encontrada nos híbridos MX 300, 2B655 e XB 6012, entretanto a maior relação folha:colmo foi verificada no híbrido XB 6012 (0,49). Observou-se maior teor de PB no híbrido PRE 32D10 (9,10% da MS), enquanto o menor teor de FDN (57,78% da MS) e celulose (24,27% da MS) foram verificados no híbrido GNZ 2500. O híbrido PL6890 apresentou maior teor de FDA (39,20 % da MS) e lignina (8,63% da MS), os demais híbridos apresentaram valores inferiores. Verificou-se menor N retido na FDN (NIDN) no híbrido RB 9308, enquanto a menor retenção de N em FDA (NIDA) ocorreu no híbrido 2B655. A menor capacidade tampão (CT) foi verificada no híbrido 2B655 (0,29). Embora haja diferenças na composição químico-bromatológica dos híbridos de milho avaliados neste estudo, recomenda-se utilizar os híbridos MX 300, PL6890 e PRE 32D10 por apresentarem produção de matéria seca mais elevada, os quais podem refletir na amortização dos custos na produção das silagens.
