Effects of intercropping beans with maize on angular leaf spot and rust of beans

Creator:: Boudreau, Mark Alan, 1958-
Abstract:: Experiments were performed to determine the nature of maize influence on bean disease in additive-type intercrops. Overall effects of intercrops on angular leaf spot (caused by Phaeoisariopsis griseola) in Kenya indicated >23% reductions (P<0.05) in area under the disease progress curve (AUDPC) in two of three season-site combinations. Fertilization tended...

Conservation of arthropod natural enemies in broccoli with relay strip-cropping

Creator:: McGrath, Daniel M. (Daniel Morton)
Abstract:: Relay strip-cropping combines two vegetation management tactics, under-sowing and strip-management. In this study conducted from 1994 though 1997, a cover crop seed-mixture containing oats (Avena sativa L. var. "Monida"), common vetch (Vicia sativa L.), red clover (Trifolium pratense L.), annual ryegrass (Lolium multflorum Lam.), and buckwheat (Fagopyrum esculentum Moench) was...

Impacts of crop level and vine vigor on vine balance and fruit composition in Oregon Pinot noir

Creator:: Vance, Amanda J.
Abstract:: Vineyard management strategies, including vineyard floor management and crop level management, can be used to influence vine vigor and fruit composition. Two studies were conducted to evaluate the impact of these practices on Pinot Noir in Oregon's Willamette Valley. Managing crop levels is common in cool climate vineyard production though...

Spring establishment of orchardgrass and tall fescue seed crops with cereal companion crops

Creator:: Chastain, Thomas G.
Abstract:: Orchardgrass and tall fescue seed crops are commonly springplanted in Oregon, but do not produce a marketable crop during the first growing season. Establishing orchardgrass and tall fescue with cereal companion crops would provide income during the seeding year and could increase seed production profits. This study was conducted to...

Managing growth and competition of a perennial ryegrass (Lolium perenne L.) living mulch in a vegetable cropping system

Creator:: Wiles, Lori Jeannine
Abstract:: Vegetable production with a living mulch may reduce soil erosion and compaction, increase organic matter levels, and decrease the requirement for chemical inputs. Competition between the vegetable and mulch, however, has limited the development of successful living mulch systems to realize these benefits. In a field study, interference between pak...

Response of 'Pinot noir' grapevines to a perennial ryegrass cover crop and irrigation in the Willamette Valley

Creator:: Wilson, William D. (William Donald), 1955-
Abstract:: A perennial grass grown in strips between the rows of grapevines, with a bare soil herbicide strip under the rows of vines, is a common form of vineyard soil management. Irrigation, though not practiced for grape culture in western Oregon at this time, could be used to supplement the soil...

Enhancement of biological control with beneficial insectary plantings

Creator:: Colley, Micaela Ruth
Abstract:: Five field experiments were conducted to evaluate the relative attractiveness of potential beneficial insectary plants to aphidophagous hover flies and parasitic Hymenoptera and the effectiveness of interplanting selected flowering plants in a broccoli field to enhance biocontrol of the cabbage aphid and green peach aphid. In 1996 we established a...

Sweet corn (Zea mays L.) production in a white clover (Trifolium repens L.) living mulch : the establishment year

Creator:: Cooper, Alan S.
Abstract:: Oregon sweet corn growers face high fertilizer, fuel and weed control costs; soil compaction, erosion, organic matter and nutrient depletion; and difficult equipment operations in muddy fields. An alternative production system might ease some of these problems. Testing was begun to evaluate a living-mulch cropping system for sweet corn (Zea...

Sweet corn (Zea mays) production in a white clover (Trifolium repens) living mulch : the second year

Creator:: Peterman, Mark K.
Abstract:: Soil-related problems common to Oregon farmers are erosion, compaction, organic matter depletion, and nutrient loss. High costs of fertilizer, fuel, and weed control are additional management problems. Growing a secondary crop as a living mulch with a primary crop may ease some of these problems. Sweet corn production in Oregon...
