Sorghum x Sudan (Multi cut)
Sorghum-sudangrass is used primarily for grazing, green chop, silage and hay. Sorghum-sudangrass hybrids also add organic matter to worn-out soils. These tall, fast-growing, heat-loving summer annual grasses can smother weeds, suppress some nematode species and penetrate compacted subsoil if mowed once. The hybrids are crosses between forage-type sorghums and sundangrass. Compared with maize, they have less leaf area, more secondary roots and a waxier leaf surface which help them withstand drought. Sorghum-sudangrass has a larger stem, less leaf area and produces more biomass than sudangrass.
Sweet Sorghum (Single cut)
Sweet sorghum, or forage-type sorghum plants are larger, leafier and mature later than grain sorghum plants. Compared with sorghum-sudangrass hybrids, they are shorter, less drought tolerant, and don’t regrow as well. Forage sorghum is an excellent choice when used for silage in a single cut system. Stems and leaves look very similar to maize.
The brown midrib (BMR) is a genetic mutation that results in a forage with a reduced lignin content, increased protein content and higher palatability than non-BMR sorghum-sudangrass varieties. Rate of animal gains are significantly increased when animals graze BMR varieties.
Sweet sorghum stalks have a high sugar content. Sweet sorghum thrives better under drier and warmer conditions than many other crops and is grown primarily for forage, silage, and syrup production.
