Cover Crop Series: Sweet Six Dry Stalk BMR Sorghum Sudan
Sweet Six Dry Stalk BMR Sorghum Sudan is a member of the Sorghum genus, all of which tend to be similar, and is a cross between a sorghum and a sudangrass. Traits that set this one apart are the brown midrib and dry stalk genetics, which leads to reduced lignin and decreased drying time when cut for hay. Sweet Six Dry Stalk BMR Sorghum Sudan is medium to tall reaching around 6 feet in height and is early to medium in maturity when compared to others in the Sorghum genus. Like most other members of the Sorghum genus, it is heat- and drought-tolerant, an excellent scavenger of soil nutrients (especially nitrogen), can have a risk of prussic acid, and is susceptible to sugar cane aphids. It is a warm-season annual but fall plantings can make decent growth before frost. Some people claim plants in the Sorghum genus are hard to burn down, possibly due to their height at maturity, but we have not had any problem. Seeding rate was 27 pounds per acre.
The Noble Research Institute is testing dozens of cover crop species with potential to help build soil health in the Southern Great Plains. This series features the cover crops we've grown on our Headquarters Farm in southern Oklahoma. These videos explore our results on establishment and growth, ground cover potential, and weed control for each crop.
