Description
Summary:his study aimed to evaluate different forage sorghum genotypes and their associated biomass, with or without bacterial-enzyme inoculant, in terms of agronomic traits and silage nutritional value in a semi-arid region. In Experiment I, we assessed six sorghum genotypes: a control (forage sorghum), a commercial sorghum (AGRI002E), and four experimental sorghums (BRS 716 202033B008 202033B011, and CMSXS7500). The experiment followed a randomized block design with six genotypes and three replications in the field. In Experiment II, we evaluated the silage produced from the six sorghum genotypes used in Experiment I. This experiment followed an entirely randomized design in a 6 × 2 factorial scheme, with six sorghum genotypes and the absence or presence of enzymatic-bacterial inoculant application, with six replications. Experiment I showed that dry matter productions of the genotypes BRS 716 and AGRI002E were 42.93% higher than that of the other genotypes, averaging 15.95 t ha−1 of dry matter. In Experiment II, silage temperatures showed increases during aerobic exposure. However, no interaction was seen between sorghum genotype and inoculant presence on silage pH values (P > 0.05) and effluent losses. The sorghum hybrids BRS 716 and AGRI002E showed the best response in terms of silage yield and nutritional value.
