Abstract

The chemical composition of four forage sorghum hybrids was evaluated under three doses of nitrogen (N). The experimental design was in randomized blocks in a 4x3 factorial scheme with four repetitions. Dry matter (DM), crude protein (CP), soluble carbohydrates (SCs), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (Hem) and lignin (Lig) were determinate through Spectrophotometry of Reflectance in Proximal Infrared. The dates were analysed for SISVAR 4.6 program comparing average by Tukey test 5% probability. The DM contents differed (P<0.05) between N doses and varieties in the first cut (21.1% to 28.7%). The PB tenors (6.4% and 7.5%) and lignin (Lig) didn’t differed (P>0.05) among varieties and N doses, both cuts. The SCs ranged between doses in the first cut and the varieties in the second cut (13.7%). The ADF and NDF tenors didn’t differed (P>0.05) in N doses in both cut, however the varieties showed difference. The Hem differed between varieties and N doses. The hybrids evaluated presented adequate chemical compositions regarding the process of ensilaging.
