Effects of Novel Sulfur Applications for pH Management of Calcareous Soil in a New Planting of Organically Grown Northern Highbush Blueberry (Vaccinium corymbosum L.) in the Columbia Basin

Creator:: Gregory, Alexander D.
Abstract:: Organically certified Northern Highbush Blueberry (NHB; Vaccinium corymbosum L.) production in the Columbia Basin region of Oregon and Washington is expanding. Soils in the region are typically calcareous and highly alkaline, often requiring pH adjustment to an ideal range of 4.5–5.5 to support the establishment of the acid-loving, ericaceous crop....

Evaluating Alternative Soil Amendments for Organic Northern Highbush Blueberry Cultivation in Sub-Optimal Soils

Creator:: Retano, Andrea
Abstract:: Escalating demand for organic blueberries has driven a significant expansion of northern highbush blueberry (NHB; Vaccinium corymbosum L.) production area. This expansion is particularly pronounced in regions of the Pacific Northwest where native soil conditions are sub-optimal for NHB, notably east of the Cascade Mountain Range of Oregon and Washington,...

Pressure trunk injections of potassium as a possible short term corrective measure for potassium deficiency in sweet cherry (Prunus avium L.) and prune (Prunus domestica L.)

Creator:: Robbins, Scott Hill
Abstract:: The effect of pressure trunk injections of K₂HPO₄, and K₂SO₄. solutions on the mineral content, growth, yield and fruit quality of sweet cherry and mineral content of prune were investigated. A complimentary study presented in Appendix 1, was conducted to evaluate the short term effectiveness of K soil amendments, mulching...

Weeds With a Purpose: Interseeding Cover Crops into Sweet Corn in Western Oregon

Creator:: Donaldson, Andrew R.
Abstract:: Cover crop establishment in late-season crops, like sweet corn, may be difficult due to the relatively short operational window following crop harvest. In regions like western Oregon, where fall-precipitation can occur when the crop is still in the field, cover crops may not be able to be planted, due to...

Characterization of geohumus for use in turf

Creator:: Patton, Ty J.
Abstract:: Geohumus is a new, unique hybrid soil amendment made of polyacrylic acid, igneous rock flour, and quartz sand. It is biodegradable and is marketed to increase soil porosity, increase plant yield, and increase plant available water by up to 30%, all while using a low inclusion rate of only 1...

Effects of boron rates and differential irrigation on bush green beans and cauliflower

Creator:: Grealish, William J.
Abstract:: Five boron rates and seven water levels were applied to bush green beans (Phaseolus vulqaris cv Oregon 91G) and to cauliflower (Brassica olereacea var. botrytis, cultivar "Snowball Y") in 1989 and 1990 to evaluate their effects on total yield of both crops and on outer quality, head hollowness and internal...

Comparison of baits for monitoring the spotted wing Drosophila, Drosophila suzukii

Creator:: Kleiber, Joseph R.
Abstract:: Spotted wing Drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is a pest of small and stone fruits that is widely distributed across much of the United States, Canada, Europe and Asia. Unlike other members of the Drosophilidae that only lay eggs in overripe or rotting fruit, SWD infest ripening and ripe...

Effects of harvest date on sweet corn maturity, sugar content and yield

Creator:: Wong, Yueh-Mei
Abstract:: Studies were conducted in 1976 and 1977 on the effects of harvest dates on maturity, yields and sugar content of four cultivars of sweet corn. The cultivars were 'Golden Cross Bantam', 'Jubilee', 'Rapidpak' and 'Tendertreat'. Moisture content of kernels ranged from 80 to 67 per cent for the six harvest...

Response of selected vegetables to various inorganic and organic nutrient sources

Creator:: Simon, James Edward
Abstract:: Fertilizer studies at the Oregon State University Vegetable Research Farm were conducted for two years to evaluate the effect of different nutrient sources on yield and selected quality components. Sources of nutrients included sewage sludge, fresh and dried poultry manure, a soybean residue from oil extraction, and several mineral fertilizers....
