Residue management and yield characteristics of fine fescue seed crops

Creator:: Schumacher, Derek David
Abstract:: 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...

Trinexapac-ethyl and open-field burning in creeping red fescue (Festuca rubra L.) seed production in the Willamette Valley

Creator:: Zapiola, Maria Luz
Abstract:: 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...

Effect of seed burial and vernalization on germination and growth of Bromus carinatus and its control with several herbicides

Creator:: Rojas-Calvo, Carlos Enrique
Abstract:: California brome (Bromus carinatus Hook & Arn), is considered an important weed infesting wheat and grass seed fields in the Willamette Valley of Oregon. Field and greenhouse experiments were conducted to study some biological aspects to develop more efficient management strategies. A field experiment was conducted to determine the effect...

Presence and pathogenicity of Fusarium and Verticillium species in commercial red radish (Raphanus sativus) seed production in the Willamette Valley of Oregon

Creator:: Bomberger, Rachel A.
Abstract:: Commercial radish seed producers in the Willamette Valley of Oregon have observed a late season wilt in their seed fields. Twenty-two fields were surveyed for wilt in the Willamette Valley during June through August 2012 and 2013. Plants exhibiting wilt symptoms were collected from the fields and examined for vascular...

Applied nitrogen effects on yellow mustard (Sinapis alba L.) production in the Willamette Valley

Creator:: DuVal, Alyssa Susan
Abstract:: Nitrogen management recommendations for yellow mustard (Sinapis alba L.) production in the high rainfall environment of Oregon's Willamette Valley (WV) are not available. The objectives of this investigation were: (i) to determine the effect of applied nitrogen (N) on seed yield and yield components in yellow mustard, and (ii) to...

Effects of grass seed agriculture on aquatic invertebrate communities in seasonal wetlands of the southern Willamette Valley, Oregon

Creator:: Wyss, Lance A.
Abstract:: An estimated 99% of native wet prairie has been lost in the Willamette Valley, Oregon, but a large number of seasonal wetlands remain on private lands dedicated to grass seed production within the historical wet prairie landscape. Because agriculture is known to alter physical and chemical wetland conditions, I investigated...

Factors affecting establishment and germination of upland prairie species of conservation concern in the Willamette Valley, Oregon

Creator:: Jones, Katherine D.
Abstract:: Identifying mechanisms that determine who lives and dies is the first step in developing successful restoration techniques for rare species and endangered habitats. We studied interactions that affect establishment of native plant forbs of conservation concern at the seedling stage to support the theoretical basis for restoration activities in Pacific...

Introducing geographic information systems to grass seed growers in the Willamette Valley of Oregon

Creator:: Hedstrom, Keldah E.
Abstract:: Oregon is the number one producer of cool-season grass seed in the United States. The center of the grass seed industry of Oregon is located in the Willamette Valley, where about 470,000 acres of seed are grown. Innovative grass seed growers of the area are beginning to implement precision agriculture...
