An irrigation efficiency model for optimum irrigation management

Creator:: Isbell, Brett, 1978-
Abstract:: Improved water use efficiencies in irrigated agriculture are necessary to assist in coping with the accelerating demand and economic competition for the world's fresh water supply and increasing ecological concerns. This will likely rely in part on optimum irrigation, which implies regulated deficit irrigation. While conventional irrigation management is intended...

Evaluation of models for estimating surface irrigation infiltration parameters : Data protocols and algorithm performance

Creator:: Isbell, Sarah A.
Abstract:: Often furrow irrigation application efficiencies are low compared to sprinkler systems. The primary goal of furrow irrigation is to infiltrate a relatively uniform target depth of water necessary for the crop, while minimizing the amount of runoff. The concept is difficult because water can infiltrate differently at all locations in...

Spring irrigation management of perennial ryegrass (Lolium perenne L.) seed production

Creator:: King, Craig Millhouser
Abstract:: Introduction of later maturing cultivars of perennial ryegrass (Lolium perenne L.) places more seed production fields in a period of drought common to Oregon during vital stages of reproductive development. During these stages, the final yield of the crop is largely determined by the number of seeds set, and the...

Spring irrigation management of tall fescue (Festuca arundinacea Schreb.) seed crops

Creator:: Orthel, Krista D.
Abstract:: Later maturing cultivars and increased ability to apply irrigation have led to inquiries by producers about proper irrigation management in tall fescue (Festuca arundinacea Schreb.) seed crops. The literature reveals little information about irrigation of perennial grass seed crops in general, and none about tall fescue in particular. Willamette Valley...

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...

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...

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...

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...

Identification of economic, social, and policy factors influencing irrigation district participation in water transactions in the Deschutes Basin

Creator:: Whitman, Cally A.
Abstract:: Surface water in the Deschutes Basin of central Oregon has been largely over allocated since the early 1900s. Therefore, rapid population growth and urban demand for water in the upper Basin lead to an increased reliance on groundwater in the last three decades. The Oregon Department of Water Resources (OWRD)...

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...
