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...
Predicting agronomic rates is important to derive optimum economic and environmental benefits from biosolids fertilizer applications. We conducted this research to 1) evaluate dryland wheat response to biosolids applications over a range of climate zones in the Pacific Northwest and 2) compare agronomic application rates predicted from yield curves with...
The use of management units for soil testing and nutrient application is an
effective strategy to increase accuracy in monitoring and managing nitrogen (N), phosphorus (P), and other nutrients. A management unit can be a group of fields, a single field, or an area within a field. To measure changes...

Extensive areas of eastern Oregon, eastern Washington, and Idaho are well suited to dryland production of small grains and legumes. Commonly, over this area, winter wheat is planted in rotation with either annual legumes or summer fallow.
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:...
The report integrates a survey of organic farmers in Oregon, Washington, and Idaho; conversations with focus groups made up of southern Oregon organic farmers and organic farming stakeholders; and interviews with Oregon State University organic agriculture researchers. It highlights research, education, and policy issues identified by organic farmers and researchers....

The fertilizer value of anaerobically-digested, dewatered biosolids in dryland cereal cropping systems was evaluated at six locations in central and eastern Washington (25 to 35 cm annual precipitation zone). Biosolids were applied at rates of 3 to 20 Mg/ha (approximately 150 to 900 kg N/ha). We measured increases in soil...
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...

Weeds in snap beans drag down yield and contaminate products sent to processors or markets. They may even make it impossible to harvest the crop mechanically. It is worth the effort to be proactive when managing weeds in row crops. Proactive rather than reactive approaches are essential to successful management...
The middle Deschutes River between Bend, Oregon and Lake Billy Chinook typically experiences critically low flows during the irrigation season. Commercial agriculture in the North Unit Irrigation District and Central Oregon Irrigation District is one major user of Deschutes River water. The overall objective of this research was to estimate...

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...
The purpose of this study was to make a preliminary
investigation of the productivity of some of the soils
within the Willamette catena under different systems of
soil management. The study was carried out at four experimental
sites near Corvallis, Oregon, during the 1962 growing
season. The soil at each...
To give the many Oregon farmers, who, are unable to leave
home to take a four-year course in the Agricultural College, a
share in the advantages of a higher education the Experiment
Station has for years conducted- farmers' institutes in various
parts of the state.
The success of these encouraged...

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...
For oysters, "The objective of these studies was to determine the biological feasibility of using the heated effluent from coastal nuclear power plants for culturing the Pacific oyster, Crassostrea gigas."

The conflict over water allocation in the Upper Klamath Basin encompasses many important, complex, and difficult questions. One aspect of the situation, energy pricing, has come under increased scrutiny in connection with relicensing of the Klamath River hydropower operations, which is scheduled to take effect in 2006.
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...
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...
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.

Oregon is the number one producer of cool-season grass seed in the United
States. The center of the grass seed industry of Oregon is located in the Willamette
Valley, where about 470,000 acres of seed are grown. Innovative grass seed growers
of the area are beginning to implement precision agriculture...
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....
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...
