Track 1-03: Development and Impact of Sown Temperate Species

Description

The use of annual ryegrass (Lolium multiflorum Lam.) as a winter cover crop and grazing option in the Southeast Unit-ed States has become a common practice. Recent research evaluating the effects of seeding time on seed yield in Canada determined autumn seeding produces the most desired results relative spring seeding, but indicated that varied autumn seeding rates would further their findings (Coulman et al. 2013). A University of Arkansas study utilized cool season annuals, wheat (Triticum aestivum L.) and annual ryegrass, to evaluate animal performance and seeding date effects. This research indicated that seeding cool-season annuals in early September may result in greater autumn forage production relative late October seeding. (Coffey et al. 2013). While current recommendations in the Southeast United States are to plant annual ryegrass in early autumn, differences among dates and locations have not been evaluated to maximize yield and provide the best forage utilization for producers. The objective of the study is to develop extension recommendations for autumn date seeding of annual ryegrass for maximum seasonal yield potential.
