Perennial Grasses
Perennial grasses provide early and late season grazing as well as hay. Grass species and varieties within species vary in several important characteristics that influence their suitability to a particular situation. The most important characteristics are maturity (how quickly the grass produces flowers in the spring), winterhardiness, stand survival, disease resistance, heat and drought tolerance, grazing and traffic tolerance.
An annual ryegrass trial was established at South Charleston in April 2004. The
trial was clipped early to promote growth (harvest 1.). Results from that trial
are reported in Table 13. Yields were higher for the mid to late maturing
varieties compared to early maturing varieties. The variety Angus 1 appeared to
behave like a true annual which completes its life cycle by the end of the first
year. It produced well through July 31, but after that did poorly as very few
tillers remained alive at the end of the season.
Annual
ryegrass (Lolium multiflorum) is a cool-season annual bunch grass native
to southern Europe. It is closely related to perennial ryegrass (Lolium
perenne). Annual ryegrass is an important short-duration grass with high
palatability and digestibility making this species highly valued for short-term
forage in livestock systems. In addition, annual ryegrass has high seedling
vigor making it well adapted to either conventional or no-till establishment.
Under good growing conditions, annual ryegrass can produce grazable forage in as
little as 45 days after establishment. This trial will be continued into 2005 to
assess winter injury and yield potential in the second year.
