Technical Abstract: Perennial ryegrass is an exceptionally high quality forage grass but its use in the northeast has been limited because it is typically not as winter hardy as other perennial forage grasses. This can be a particularly difficult problem for winters such as 2013-2014 which experienced wide-spread and long lasting cold conditions. Substantial research over the years has shown that pasture productivity can be improved by sowing multiple species from different functional groups but little is known about the benefits, if any, of sowing multiple cultivars within a species. This multi-state project (ME, NH, VT, and PA) compared the productivity and persistence of 1-, 3- and 5-cultivar mixtures of perennial ryegrass selected for differences in heading date, winter hardiness, and ploidy. Plots contained white clover as a nitrogen source and were managed according to organic farming practices. This presentation will include yield data from the 2013 growing season and winter survival data collected in the spring of 2014.
