“…A higher panicle participation is a desirable characteristic because it allows for a greater grain yield and higher nutritive value of the silage. In addition, dual-purpose forage hybrids can combine mass and grain yield, which highlights the importance of panicle production (A. L. Silva et al, 2020).…”

“…The CP content is related to the agronomic behavior of the genotype. Because these plants are dual purpose hybrids, they have shorter stems with a higher proportion of leaves and grains, which as well as the stage of maturity and soil and climate conditions of the growing area, contribute to this characteristic (A. L. Silva et al, 2020 FEPAGRO 11, SF 25, 947072, SF 11, 12F042422, 12F042224, 9929036, 947216, 9929026, 9929012, SF15, and 12F042066 were grouped as having the highest NDF content, which ranged from 619 to 702 ± 27.9 g kg -1 . Variation in the aNDF content is attributed to the consumption of nonstructural carbohydrates, carried out mainly by lactic acid bacteria.…”

The objective of this study was to identify the hybrids of sorghum most suitable for the production of silage in the semiarid regions of northeastern Brazil. Twenty-three hybrids were evaluated in a randomized block design with three replicates. The dry mass yield; dry mass of leaf, stem, panicle, grains, and senescent matter; and chemical composition of the plant were evaluated. The pH, ammoniacal nitrogen (N-NH3), and chemical composition of the silage were also assessed. The hybrids 947252, FEPAGRO 18, 12F042226, and SF 11 performed best in terms of morphological characteristics, with the highest mass of leaves and grains. The hybrid FEPAGRO 19 had the highest dry matter value (443.3 ± 17.0 g kg-1), whereas the hybrid 12F042496 had the lowest value (271.3 ± 17.0 g kg-1). The dry matter (DM) content of the other hybrids was within the recommended values for silage production (280 to 400 g kg-1). High levels of crude protein were observed in the grouped hybrids 12F042496, 947254, and 12F042422. The hybrid 12F042496 had the highest neutral detergent fiber content. The hybrids 9929036, 9929030, 9929012, 947254, 947072, PROG 134 IPA, 12F042226, 12F042422, and BRS 506 had pH values ranging between 3.8 and 4.2, indicating good quality silage. Overall, the sorghum hybrids 9929030, 12F042224, 12F042150, FEPAGRO19, and FEPAGRO11 had the best growth and production characteristics, and plant and silage chemical composition, and are thus recommended for the production of silage in the semiarid of northeastern Brazil.

Agronomic characterization and chemical composition of sorghum hybrids for silage making in rainfed conditions

Abstract: There are large morphological variations between sorghum hybrids. Forage production among sorghum hybrids varies up to 61.76 t ha -1 . The chemical composition of sorghum is influenced by its morphology.
