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.
New varieties and advanced breeding lines of forage and turf grass species were grown under Oregon conditions to evaluate their seed yield potential. Seed harvest dates and clean seed yields for 146 entries are reported for 1982 and 1983, and ranked as a percent of the standard variety for each...
Chewings fescue [Festuca rubra L. subsp. fallax (Thuill.) Nyman] is a desired turfgrass with dense sod forming capabilities and superior shade tolerance. Thermal residue management (open-field burning) has traditionally been used to remove post-harvest residue and maintain seed yield over the life of the stand. However, alternative non-thermal residue management...
A greater than 10-fold increase in Canada goose (Branta canadensis) populations over the past several years has resulted in concerns over grazing impacts on grass seed production in the mid-Willamette Valley, Oregon. This study was designed to develop methods to quantify and statistically analyze goose-grazing impacts on seed yields of...
Open-field burning has been an effective, economical, and widespread method of post-harvest residue management in creeping red fescue seed production in the Willamette Valley since the late 1940s. However, the use of field burning has been legislatively restricted due to air quality and safety issues. The foliar-applied plant growth regulator...
