Crop and tree response to planting patterns in alley cropping systems

Creator:: Seiter, Stefan
Abstract:: Growing trees as a green manure crop together with an annual food crop is a new technology for farmers in Oregon. To promote farmer participation and to acquire a broad knowledge of the processes involved in species interactions, three feasible alley cropping and two sweet corn monocrop planting patterns were...

Soil temperature suppression on growth and yield of potato (Solanum tuberosum L.) in warm climates of Sri Lanka

Creator:: Tharmarajah, S. K.
Abstract:: Potato (Solanum tuberosum L.) is one of the most productive and nutritious food crops. Due to its adaptability to cool climates, production in Sri Lanka has been restricted to erosion-prone highlands. Vast potential exists for expansion of potato cultivation in the lowlands while production areas in the highlands are limited...

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...

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...

On-farm inquiry and assessment of tillage and cover cropping for white mold control in snap bean production

Creator:: Harrison, Elizabeth Langham.
Abstract:: Cultural practices in snap bean production were evaluated at the Oregon State University Vegetable Research Farm Corvallis, Oregon. In addition, decision-making in snap bean production was assessed on five farms in the Coburg-Junction City-Harrisburg regions of the Willamette Valley, Oregon. A field experiment with cover crop and tillage techniques was...

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...

Early detection of weed resistance : pattern-thinking and rapid microcalorimetric assay

Creator:: Suwanagul, Duangporn
Abstract:: Weed resistance is usually diagnosed after a weed control practice has lost efficacy and weed populations begin to increase rapidly. Prediction and validation in the field at a very early stage of resistance development is a promising method for preventing an uncontrollable problem. Pattern-thinking helped individuals connect their experience of...

Direct-seeded cucurbit cultivation in Oregon and tropical South America

Creator:: McCombs, Avery
Abstract:: Cucurbits are grown in production agriculture in Oregon as well as in smallholder agriculture in tropical South America. Experimental research was performed at the OSU Research Farm in 2001 with direct-seeded cucurbits, and literature reviews were conducted to develop a characterization of smallholder farming in tropical South America. The two...

Whole system perspective : Steelhead, Onchorhynchus mykiss, glutathione s-transferase as a biomarker of chlorpyrifos exposure

Creator:: Pecore, Rachael G.
Abstract:: Organophosphate insecticides may produce sublethal, adverse effects on salmonid growth, reproduction, maturation, swimming, and feeding. Chlorpyrifos, an organophosphate insecticide, was detected by the Oregon Department of Environmental Quality in the Hood River and tributaries during March 1999 at levels exceeding state water quality standards in the range of 0.011-0.482 μg/L....
