Iron and Clay Cowpeas are heat- and drought-tolerant legumes. They are adapted to a range of soils and seem to be relatively pest-free. Like all cowpeas, they can also be consumed by humans in the form of snap beans and dry beans. Iron and Clay have a long season of vegetative growth before flowering and will make vines that will run along the ground or climb up other plants, if given the chance. Seeding rate was 54 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.
