A vigorous, competitive and adaptable hybrid annual that likes heat and high fertility. It can be harvested as pasture, green chop, hay, or silage. Flail chopping after frost or killing the cover crop with herbicide will create a suitable mulch for no-till planting, preserving soil life and soil structure in non-compacted fields. This makes them a prime candidate for dual purpose use as both cover crop and forage. Green-chopping frost-damaged plants will lower the risk compared with grazing directly, because animals are less likely to selectively graze damaged tissue. It is commonly used as a versatile forage option for grazing, hay, or silage. Flail chopping after frost or killing the cover crop with herbicide will create a suitable mulch for no-till planting, preserving soil life and soil structure in non-compacted fields. Frost/freeze events are obvious condition that can lead to plant cell rupture, in addition cutting, chopping, chewing, drought, and maturity are additional sources. Sorghum-sudangrass hybrids have coarser stems and broader leaves than true sudangrass. sudanense) has high palatability and does not produce toxic compounds that threaten livestock and horses (Mojtahedi et al.
