Winter Squash: Production and Storage of a Late Winter Local Food

Creator:: Wetzel, Jennifer D.
Abstract:: Winter squash is an important late winter vegetable crop for local and regional markets; however, farmers in western Oregon report that this crop is marginally profitable due to losses in storage and relatively low yields for the high culinary value kabocha and buttercup types. In order to increase the sales...

Farmer perspectives on the transition to organic agriculture : an Oregon study of farmer motivations and barriers

Creator:: Lloyd, Deanna M.
Abstract:: In the midst of double-digit growth in market demand for organic products, there is a lag in the growth of certified organic production in the United States. This thesis investigated the motivations and barriers farmers face when making the transition to organic agriculture. Three distinct organic farmer typologies were identified:...

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...

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...

Right as rain? The value of water in Willamette Valley agriculture

Creator:: Kalinin, Alexey V.
Abstract:: Signs of climate change across the Pacific Northwest indicate changing patterns of timing and availability of stream flow. Declining summer low flows, decreasing snow pack, higher temperatures and an increasing fraction of mountain precipitation falling as rain, raise concerns about future reliability of stream flows. These changes will likely affect...

Farm and community-level impacts of irrigation water supply reductions : a case study of Malheur County, Oregon

Creator:: Wyse, Barbara J.
Abstract:: Agricultural water supplies are becoming increasingly uncertain in the western United States due to rising demand from competing water users, environmental restrictions on surface water withdrawals due to water quality and endangered species concerns, and, potentially, climate-induced hydrological changes. Since many rural areas in the West depend economically upon irrigated...

What are the environmental, economic, and social barriers to achieving agricultural sustainability in the Ten Rivers region of western Oregon?

Creator:: Stanton, Michael
Abstract:: This ethnographic study examined some of the ways that global markets and the infrastructure of agribusiness affect local smallholder farmers in the Ten Rivers region who are transitioning toward more sustainable and traditional agricultural methods. The purpose of this research was to discover what barriers smallholder farmers face in developing...

Improving nitrogen management with cover crops in organic broccoli production

Creator:: Garrett, Amy
Abstract:: Legume cover crops can serve as important sources of nitrogen (N) in sustainable agriculture and can be economically beneficial when fertilizer inputs are reduced without a yield reduction. Synchronizing N mineralization from organic materials with the needs of the subsequent crop is a challenge for organic growers. Predicting plant available...

Assessing landscape complexity using remotely sensed and field based measurements : does landscape complexity drive leafroller parasitism rates on Oregon caneberry farms?

Creator:: Winfield, Tammy L.
Abstract:: Landscape heterogeneity is thought to differ among farm management types (i.e. organic and conventional), and this difference is hypothesized to result in variations in pest control by natural enemies. However, it is unclear if these variations in pest control are driven by landscape structure or by farm management practices themselves....

Irrigated agriculture, energy, and endangered species in the Upper Klamath Basin : Evaluating trade-offs and interconnections

Creator:: Boehlert, Brent B.
Abstract:: In 2001, an extreme drought tightened water supply in the Upper Klamath Basin (basin) while earlier increases in Endangered Species Act (ESA) water requirements for basin fish species that same year elevated demands. The Bureau of Reclamation (Reclamation), which manages irrigation water in parts of the basin located near the...
