The objective of this study was to evaluate four sorghum ensilages under nitrogen rates, regarding the nfermentative characteristics, such as, dry matter content of original matter (DMom) and silage (DMs), crude protein of original matter (CPom) and silage (CPs), pH, tenors of the volatile fatty acids, densities of wadding (Dw) and opening (Do), productions of gas (Gas) and effluent (Efl). The experimental design was in randomized blocks in a 4×3 factorial arrangement with four replications. The cultivars used in this study were 1F 305, 0369 267, 0369 255 and BR 700, and the three rates of nitrogen under ammonium sulphate form were 0; 60 and 120 kg N.ha-1.The tenors of DMmo differed (P<0.05) among N rates and the evaluated hybrids, presenting a variation of 21.82 to 28.17%. Values of DMs only differed (P<0.05) between the hybrids 1F305 and 0369 267, with averages of 27.6 and 27.8%, respectively. The concentration of lactic acid differed (P<0.05) among cultivars and treatments varying from 3.60% to 4.55%. The tenors of acetic acid differed only for BR 700, varying from 1.29% to 1.52%. The tenors of propionic acid differed (P<0.05) among cultivars, varying from 0.17% to 0.24%. The densities Dw and Do of the experimental silos did not differ between the hybrids, except the 0369 255.KEYWORDS: fermentative parameters; nitrogen fertilization; pH; Sorghum bicolor; volatile fatty acids
