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...

Weed suppression in vegetables with residues of 'micah' barley (Horedeum vulgare L.) and other spring cereals

Creator:: Chongwe, Edgar Happy
Abstract:: Three experiments whose objectives were to investigate cover crop kill by winter freeze, weed suppression by 'Micah' barley and other spring cereals, and allelopathic potential of cereal covers were conducted at the Vegetable Research Farm and in the greenhouse and growth chamber facilities at OSU in 1989/90. Kill by winter...

Cereal residue effects on weeds and cucumbers

Creator:: Peachey, Ronald Edward
Abstract:: Cereal residues suppress the development of small seeded, summer annual weeds. The focus of this study was to determine whether cereal residues can be used to suppress weeds in cucumber production systems in the Pacific Northwest. In the first of three experiments, cereal residues of fall-planted, spring-killed cover crops suppressed...

Enhancement of the weed competitive ability of lowland rice (Oryza sativa L.) cultivars

Creator:: Ranasinghe, Lakshman L.
Abstract:: Most of the presently grown cultivars of rice (Oryza sativa L.) have poor competitive ability against weeds if compared with traditional cultivars. Therefore, effective weed control is an important but often costly and difficult management practice in rice crop production. If weed competitive ability of rice cultivars could be improved...

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...

Evaluation of natural and synthetic preemergence herbicides used in ornamental landscapes

Creator:: Hilgert, Christopher
Abstract:: A series of field experiments conducted at the Lewis-Brown horticulture farm at Oregon State University evaluated the performance of four preemergence herbicides in simulated ornamental shrub beds. Two natural products, corn gluten meal (CGM) and meadowfoam seedmeal (MFS), were used along with two synthetic products, prodiamine purchased under the trade...

Multiple pest suppression with cover crops in strawberry

Creator:: Datta, Braja Bandhu
Abstract:: The experiment was conducted to compare multiple pest (weed, soil arthropod and diseases) suppression by cereal cover crops in 'Selva' and 'Totem' strawberry. In addition, perlite was used to compare improvement of soil and root aeration which might modify strawberry black root rot complex. Small-seeded summer annual weeds were suppressed...

Structuring habitat to conserve ground beetles (Coleoptera: Carabidae) and reduce summer annual weeds in agroecosystems

Creator:: Green, Jessica M.
Abstract:: Weed management in sustainable farming systems often requires the integration of several different pest management techniques. Cultural, biological, and chemical pest control efforts can be utilized to contribute to the common goal of reducing weeds in vegetable row crop systems. This research addresses how common disturbances such as tillage and...

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...
