Water and Soil Management Practices to Enhance Plant Growth, Berry Development, and Fruit Quality of Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Almutairi, Khalid F.
Abstract:: Drought and mandatory water restrictions are limiting the availability of irrigation water in many important blueberry growing regions and new strategies are needed to maintain yield and fruit quality with less water. Three potential options for reducing water use, including deficit irrigation, irrigation cut-offs, and crop thinning, were evaluated for...

Basin-wide distributed modeling of hydrologic responses to irrigation management in the Wood River Basin, Klamath County, OR

Creator:: Owens, Joshua M.
Abstract:: The Wood River Basin lies upstream of Upper Klamath Lake, the main reservoir of the USBR Klamath Irrigation Project that provides irrigation water to 210,000 acres of downstream land. Water allocation became a contentious issue in 2001 when drought led to curtailment of irrigation deliveries to the Klamath Irrigation Project...

Addressing Data Resolution in Precision Agriculture

Creator:: Kelley, Jason
Abstract:: Irrigated agriculture constitutes the greatest consumptive water use globally, so that irrigation efficiency measures are an important part of global efforts to best utilize this limited resource. However, greater irrigation efficiency must be achieved while simultaneously maintaining or increasing crop yields and farming profitability. Incremental water use decisions are made...

Estimating the value of irrigation water transferred to instream flow : A case study of Umatilla County, Oregon

Creator:: Ugrinska, Monika P.
Abstract:: Agricultural water supplies are becoming increasingly uncertain in the western United States due to elevated demands from competing water users, environmental restrictions on surface water withdrawals as a result of the establishment of the Endangered Species Act in 1973, and potential climatic changes. Since many rural communities in the West...

Beyond random acts of conservation : an institutional analysis of the Natural Resource Conservation Service's Agricultural Water Enhancement Program

Creator:: Burright, Harmony S. J.
Abstract:: Irrigated agriculture accounts for 90 percent of consumptive use of freshwater in the western US and is considered the largest contributor to nonpoint source water pollution. The diffuse nature of most water quality and quantity challenges necessitates institutions that can more effectively engage agricultural producers in strategic, integrated, watershed-scale approaches...

Irrigation choices for major West Coast crops : water scarcity and climatic determinants

Creator:: Olen, Beau
Abstract:: Recent climate change forecasts have aroused growing interest in the influence of water scarcity and climate on agricultural production and irrigation practice. However, it is common in the economic literature to aggregate disparate crops when modeling irrigation choices. That approach confounds the crop-specific effects of climate and water scarcity that...

Establishing irrigation criteria for cultivation of Veratrum californicum

Creator:: Doniger, Alison R.
Abstract:: Veratrum californicum (common name: corn lily) is a wild plant species that grows in the Intermountain West, its range extending from British Columbia to Mexico. Corn lily is of interest because it has the potential to provide pharmaceutical precursors for use in the treatment of cancer. Pharmaceutical companies are currently...

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...

A spatially explicit model for allocating conservation efforts : the Grand Ronde River basin, Oregon

Creator:: Watanabe, Michio
Abstract:: The spatial and dynamic pattern of landscape changes has a profound effect on the supply of environmental services, including the provision of habitat for fish and wildlife. Spatial heterogeneity is a common feature of landscapes in the Pacific Northwest, most notably in areas important to the production of salmonid fish...

Residential water conservation and energy efficiency impacts through effective scheduling and opportunities for regional expansion : a case study of a gas tankless water heater with recirculation loop

Creator:: Johnson, Erica M.
Abstract:: This study focused on the potential water and energy savings from implementing a revised schedule of a recirculation pump connected to a condensing gas tankless water heater located in a study home in Portland, Oregon. The existing recirculation pump activation schedule was studied for its impact on the overall water...
