Cover Crop Series: Sweet Forever BMR Sorghum Sudan
Sweet Forever 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. One trait that sets this one apart is the brown midrib genetics, which leads to reduced lignin. Sweet Forever BMR Sorghum Sudan is not always advertised as being photoperiod sensitive, but it does have the PPS trait and does not flower until the end of summer. It gets relatively tall in height, easily exceeding 6 feet, and is late 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.
