Effects of nitrogen source, rate and a nitrification inhibitor on soil nitrogen status and mineral composition of strawberry

Creator:: Marion, Carol I.
Abstract:: Three rates of urea, urea-DCD, and NH₄N0₃ were soil applied in April and August 1986 to strawberry selection OR-US 4930 and cultivar 'Sumas' to determine effects of the nitrification inhibitor dicyandiamide (DCD) and nitrogen source and rate on soil NH₄ and N0₃ levels, fruit yield and quality, and mineral composition...

The use of 2, 4-d, paraquat and dinoseb for control of filbert (Corylus Avellana L.) suckers

Creator:: Reich, Jack Ernest
Abstract:: The control of filbert (Corylus Avellana L.) suckers by means of herbicides was investigated in three phases during 1968 and 1969. (1) Screening trials, on canned filbert trees in the greenhouse, to determine the effectiveness of various herbicides and concentrations in controlling vegetative growth. (2) A summary experiment in the...

Nursery container weeds response to modification of substrate pH, substrate particle size and applied nitrogen form

Creator:: Wada, Sugae
Abstract:: Experiments were conducted to determine the influence of cultural management practices on weed growth in nursery containers. Experiments 1 and 2 evaluated the effects of dolomitic lime rate and application method on substrate pH, creeping woodsorrel (Oxalis corniculata L.) establishment in containers, and growth of azalea (Rhododendron ‘Rosebud’) and pieris...

Nutrient management of blackberry cultivars grown in organic production systems

Creator:: Fernandez-Salvador, Javier A.
Abstract:: The impact of fertilizer source and cultivar on growth, fruit quality, and yield was evaluated in organic blackberry (Rubus L. subgenus Rubus Watson) from 2011-2013 in three studies. In all studies, plants were drip irrigated, and weeds were managed using a woven polypropylene, permeable landscape fabric (weed mat). At a...

Weed Management, Training, and Irrigation Practices for Organic Production of Trailing Blackberry : Plant Growth, Yield, and Nutrients

Creator:: Dixon, Emily K.
Abstract:: There is limited information available on production of trailing blackberry, particularly certified organic plantings, which are of interest to growers as there is increased consumer demand and a price premium over conventionally-produced fruit. Various production strategies were evaluated for their effect on yield, biomass production, carbon (C), and nutrient concentrations...

Weed, water, and nutrient management practices for organic blackberry during establishment

Creator:: Harkins, Renee H.
Abstract:: The study was conducted in an organic trailing blackberry (Rubus L. subgenus Rubus, Watson) planting established at the North Willamette Research and Extension Center in Aurora, OR on 26 May 2010. Three weed management systems were compared for 'Marion' and 'Black Diamond': 1) non-weeded; 2) hand-hoed two to three times...

Using stable isotopes and visual gut examination to determine the diet composition of Pterostichus melanarius (Coleoptera: Carabidae) in western Oregon vegetable row crops

Creator:: Moulton, Laurel A.
Abstract:: The omnivorous ground beetle, Pterostichus melanarius Illager (Coleoptera: Carabidae), is a ubiquitous inhabitant of western Oregon crop land. Because it is often the most abundant ground beetle, and attains densities that could lead to serious impacts on its prey sources, I sought to understand the overall diet composition, and specifically...

Exploring the biology and monitoring techniques of two economically impactful Chrysobothris species in Oregon hazelnuts

Creator:: Rudolph, Erica
Abstract:: Chrysobothris mali Horn and C. femorata Olivier (Coleoptera : Buprestidae) are two flatheaded wood boring beetle species that have become economically impactful pests in North American high value tree cropping systems. Both species are native to North America, with C. femorata occurring across the continent (Wellso and Manley 2007), whereas...

Improving Honey Bee Health: Evaluating Efficacy and Safety of Oxalic Acid Vaporization Tactic for Varroa destructor Control and Understanding Factors Triggering European Foulbrood Disease

Creator:: Bozkus, Mustafa
Abstract:: Honey bees are vital for our food production and ecosystem due to their critical pollination services. The beekeepers in the United States and worldwide have reported significant colony losses for over fifteen years. Several stressors are implicated in these colony declines, including parasites, diseases, poor nutrition, and pesticide exposure. There...
