Orchardgrass, fertilized with 500 pounds per acre of elemental nitrogen annually, produced the highest 2-year average forage yields. Compared to the 500-pound per acre rate, the application of 1000 pounds of elemental nitrogen generally reduced the yields of orchardgrass, timothy, and bromegrass. Grass-legume mixture yields were higher with timothy than with bromegrass or orchardgrass. Interactions between grass species and treatments and differences between strains within species were significant.
