Warm season cover crops have the potential to fill fallow periods between vegetable crops, after field crop harvest, or act as living mulches in cash crop plantings. Substantial research has been conducted on using cool-season cover crops in southeastern crop rotations, but much less work has been completed on the use of warm-season cover crops in this region. The objective of this study was to evaluate the growth characteristics and biomass production of 23 commercially available warm-season cover crop varieties of 15 warm-season species on the coastal plain of the Southeast.
