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...

Creator:: Orthel, Krista D.
Abstract:: Later maturing cultivars and increased ability to apply irrigation have led to inquiries by producers about proper irrigation management in tall fescue (Festuca arundinacea Schreb.) seed crops. The literature reveals little information about irrigation of perennial grass seed crops in general, and none about tall fescue in particular. Willamette Valley...

Creator:: Fiez, Timothy E.
Abstract:: Meadowfoam (Limnanthes R. Br. spp.), a source of C₂₀ and C₂₂ fatty acids, is a new industrial oilseed crop adapted to the Willamette Valley of Oregon. Increased oil yield per land area may increase the rate of meadowfoam commercialization. Using two half-sib L. floccosa x L. alba lines, 85-765 and...

Creator:: Kennedy, Ralph C.
Abstract:: Fiber flax (Linum usitatissimum L.) production in the Willamette Valley ended in Oregon around 1957 before newly developed technology and fiber cultivars were available. The purpose of this research was to explore the use of modern methods and new cultivars. Field studies were conducted to evaluate cultivars and optimum cultural...

Creator:: Faletti, Matthew T.
Abstract:: Field experiments were conducted in 2002 and 2003 in the Willamette Valley of Oregon to investigate the effects of two plant growth regulators on the growth and reproduction of the weed annual bluegrass. Previous research suggested that the plant growth regulator prohexadione-calcium hastened senescence of annual bluegrass. Another plant growth...

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...

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...

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...
