Forty perennial and 12 annual grass varieties were evaluated for seed production potential at Corvallis, Oregon. Perennial ryegrass, orchardgrass, Kentucky bluegrass, red fescue, Chewings fescue, tall fescue, and annual ryegrass were included in the study. Results of 1986 and 1987 harvest years are reported.
Research reported here was done by or in collaboration with the people listed on each report. In most cases, a landowner cooperated as well. Each study was conducted over a 2-year period because first-year control of perennial weeds is not necessarily indicative of long term control.
