Evaluating the Attractiveness of Pacific Northwest Native Plants to Insects and Gardeners

Creator:: Anderson, Aaron G.
Abstract:: Due to a growing body of literature documenting declines in pollinator populations, there has been increased public interest in pollinator conservation. In urban and suburban landscapes, many gardeners and urban land managers are interested in gardening for pollinators, particularly bees. Simultaneously, many homeowners and municipalities are interested in other aspects...

Effects of irrigation and nitrogen on cauliflower development, yield and quality

Creator:: Bratsch, Anthony D.
Abstract:: Field experiments were conducted with cauliflower (Brassica oleracea var. botrytis cv. Snowball Y ) to determine crop development, yield, quality and maturity response to various seasonal water levels, and to specific water stress timing in relation to curd initiation. The effects of nitrogen rate, timing, and source and the application...

Modeling purple nutsedge (Cyperus rotundus L.) growth : preliminary evaluation of light intensity, soil moisture and herbicide effects

Creator:: Amerasinghe, A. A. L.
Abstract:: Purple nutsedge [Cyperus rotundas L.) has been recognized as one of the most troublesome perennial weeds of agricultural lands in tropical and some temperate regions. This research sought to determine the effects of timing of herbicides, shading, and soil moisture on plant population growth and tuber production of purple nutsedge...

The Impact of Temperature on Halyomorpha halys (Hemiptera: Pentatomidae) Life Table Parameters and Feeding Pressure

Creator:: Maslen, Erika A.
Abstract:: Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an invasive insect pest that has become established and problematic in the Pacific Northwest. Known colloquially as the brown marmorated stink bug (BMSB), H. halys causes direct damage through feeding activity on a wide range of agronomic and horticultural crops. The objectives of this...

Effect of row cover and supplemental Ca fertilization on blossom-end rot in bell pepper (Capsicum annuum var. annuum, Grossom Group)

Creator:: Alexander, Shara E.
Abstract:: A 2-year trial was conducted at Oregon State University's Hermiston Agricultural Research and Extension Center to examine the effects of spunbonded row cover and supplemental calcium fertilization on blossom-end rot in two varieties of bell pepper. Blossom-end rot is a common cause of bell pepper yield losses, especially at the...

The effect of ethylene manipulation on flower bud development of prunus persica and prunus domestica and of pyrus communis ovule senescence

Creator:: Crisosto, Carlos H.
Abstract:: In the Northwest, two tree fruit production problems may be related to the role of ethylene on plant growth and development: flowers and developing fruits are subject to low temperature injury during early spring, and to the low fruit set of 'Comice'. Ethylene may be involved in influencing dormancy and...

Nitrogen use in container-grown woody ornamentals

Creator:: Sandrock, David Ray, 1971-
Abstract:: Lasting, effective solutions to nitrogen (N) loss from container nurseries must address layers of complexity ranging in scale from whole system nursery management to gene expression. Group-based On-site Active Learning (GOAL) was developed to aid nursery managers and related stakeholders (e.g. neighbors, policy makers, regulating agencies, researchers) in developing a...
