Marshall Ryegrass is a variety that was released by Mississippi State University in 1981. Marshall is highly sought after for its extreme cold tolerance, especially for northern pastures where Gulf Annual Ryegrass just cannot tolerate the colder temperatures. Product Detail Extreme cold tolerance High yields in forage production Cover crop, forage or hay production Rapid germination Tolerant to close grazing   Product Information Application areas for Marshall Ryegrass vary depending on the intended use. Primarily, Marshall Ryegrass is used for pastures where it has high yields in forage production. Marshall provides dramatically better steer weight gains as well, in comparison to Gulf Annual Ryegrass. Marshall Ryegrass can be used as a cover crop, forage, or hay production. Marshall Ryegrass establishes rapidly, which makes it an excellent choice for soil protection and weed management. Marshall Ryegrass has a moderate tolerance to wet soils and temporary flooding. Marshall Ryegrass adapts well to various soil types, where little preparation is needed for rapid germination. In trials, Marshall Ryegrass has shown superiority to Gulf Annual Ryegrass in both cold tolerance and tolerance to close grazing, especially in the north. Ryegrass is a cool season variety, plant once nighttime temperatures are consistently 65 degrees and below.
