Russet Burbank response to nitrogen fertilization and planting date

Creator:: Thornton, Robert Kim, 1957-
Abstract:: Studies addressed impacts of planting dates and variable N applications on numbers and size of Russet Burbank stems and stolon nodal position in relation to tuber growth and levels of hollow heart (HH) and brown center (BC). Low preplant N regimes produced larger tubers and final yields, and less HH...

Soil biochemical measures as ecological indicators across agricultural and forest ecosystems of Oregon

Creator:: Knight, Timothy R.
Abstract:: A variety of soil properties have been proposed and tested as potential indicators of soil quality. This study was conducted in an effort to produce a standardized soil quality index for systems in Oregon. Soils in both forested and agricultural systems were sampled in a wide variety of locations, climates,...

Genetics of low erucic acid and cytological analyses of wide hybrids in meadowfoam

Creator:: Gandhi, Sonali Dilip
Abstract:: Cultivated meadowfoam (Limnanthes alba Benth.) is an annual oil seed crop native to southern Oregon. California and British Columbia. The genus Limnanthes is composed of nine species and divided into two sections, Inflexae and Reflexae. The seed oil of meadowfoam is a rich source of erucic acid and several novel...

Performance of perennial ryegrass (Lolium perenne L.) seed crops under water stress conditions

Creator:: Velloza, Theodosius Marmaduke
Abstract:: Summer drought is a major factor limiting the regrowth of perennial ryegrass seed crops. This phase of crop development has a strong influence on seed yield because most of the tillers that contribute towards next season's seed crop are produced or regrown during this period. In recent years many seed...

Spring irrigation management of perennial ryegrass (Lolium perenne L.) seed production

Creator:: King, Craig Millhouser
Abstract:: Introduction of later maturing cultivars of perennial ryegrass (Lolium perenne L.) places more seed production fields in a period of drought common to Oregon during vital stages of reproductive development. During these stages, the final yield of the crop is largely determined by the number of seeds set, and the...

Seed Development in Orchardgrass (Dactylis glomerata L.) in Relation to Plant Growth Regulators and Spring Nitrogen

Creator:: Morad, Mohammed M.
Abstract:: Orchardgrass (Dactylis glomerata L.) is an important seed crop, but unlike other cool-season perennial grass seed crops such as perennial ryegrass (Lolium perenne L.) and tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.], seed yields have not increased over time so there is considerable room for improvement. Research suggests that plant growth...

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...

Spring Nitrogen, Plant Growth Regulator, and Defoliation Effects on Seed Production in Two Fine Fescue (Festuca rubra L.) Species

Creator:: Anderson, Nicole P.
Abstract:: One important cool-season perennial grass seed crop grown in Oregon is fine fescue (Festuca rubra L.). Open-field burning has been used for many decades to manage pests, cycle nutrients, and stabilize yield, in fine fescue seed fields, especially as stands age. Legislative restrictions currently limit open-field burning to 6,070 hectares...

Short-term responses of native bees to livestock and implications for managing ecosystem services in grasslands

Creator:: Kimoto, Chiho, DeBano, Sandra J., Thorp, Robbin W., Taylor, Robert V., Schmalz, Heidi, DelCurto, Timothy, Johnson, Tracey, Kennedy, Patricia L., and Rao, Sujaya
Abstract:: Rangelands are significant providers of ecosystem services in agroecosystems world‐wide. Yet few studies have investigated how different intensities of livestock grazing impact one important provider of these ecosystem services—native bees. We conducted the first large‐scale manipulative study on the effect of a gradient of livestock grazing intensities on native bees...

Abstract:: In horticultural nurseries for container-grown plants, production and sales have been threatened by the presence of a quarantined plant pathogen, Phytophthora ramorum (causal agent of sudden oak death). Infested nursery beds are an important source of P. ramorum, which can initiate disease through movement with surface water to infect roots...
