Yield and nutritional value of silage of different sorghum hybrids inoculated with <i>Azospirillum brasilense</i>

The objective of this study was to evaluate sorghum hybrids associated or not with Azospirillum brasilense and nitrogen fertilization (N) during planting on the yield, fermentative profile, nutritional value respective silages. Five (Volumax, 201813B, 201814B, 201709B, BRS716) were evaluated three strategies using urea (100 kg ha−1 N) brasilense, N)/A. in association. A randomized block design used a 5 × 3 factorial scheme, five hybrids, replications (blocks). useful area each experimental unit m x m. biomass showed dry matter (DM) production (P = 0.01) 48.31% higher than DM Volumax forage (mean 17.49 t matter). There no difference between hybrid silages pH values 4.11; P 0.68), gas losses 3.74% DM; 0.19). 201709B BRS 716 better digestible productivity. can be as strategy partial total replacement urea.
