Northern Research and Demonstration Farm
In response to questions about the suitability of some relatively new or different forage grass species for northern Iowa, a variety trial was initiated in 2010 with a few examples of alternative forage grasses. Among the entries tested were two intermediate wheatgrass varieties and two meadow bromegrass varieties.
