Oregon crop water use and irrigation requirements

Creator:: Oregon State University. Extension Service and Cuenca, Richard H., 1947-
Abstract:: Provides consumptive use and net irrigation requirements for economically important crops in 27 climatic regions in Oregon. Computations are based on the modified Blaney-Criddle calculation method and climatic database information. Contains tables of: 1) The typical growing seasons of selected Oregon crops by region and 2) Crop water (ETcrop) and...

Agronomic guidelines for flexible cropping systems in dryland areas of Oregon

Creator:: Lutcher, L. K. (Lawrence K.), Wysocki, Donald John, 1952-, Corp, Mary K., Horneck, Donald Arthur, and Oregon State University. Extension Service
Abstract:: Flexible cropping systems allow for an opportunistic change in an established rotation. Plant-available soil water is the most reliable indicator of potential yield.

Water relations in red and white clover seed crops

Creator:: Oliva, Ruben N.
Abstract:: Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover seed yields can be highly variable and low in western Oregon. The objectives of this study were to: i) determine crop water requirements and supplemental irrigation timing, and ii) quantify the effects of soil and water status on inflorescence...

Seasonal and diurnal trends of leaf water potential and stomatal conductance of red alder (Alnus rubra Bong) growing along a density gradient in western Oregon

Creator:: Lu, Shengjun
Abstract:: Three Nelder plots of 3-year-old red alder (Alnus rubra Bong) were used for this study at the Cascade Head Experimental Forest, Oregon in the growing season of 1988 at an elevation of 330 meters. Each Nelder plot represented a range of densities from 238 to 101,219 trees per hectare. The...

Effects of bedrock water availability on growth and ecophysiology of Douglas-fir (Pseudotsuga menziesii) and Pacific Madrone (Arbutus menziesii) in southwest Oregon

Creator:: Wang, Zhengqi
Abstract:: Effects of bedrock water availability on growth and ecophysiology of Douglas-fir [Pseudotsuga TnenzieSii (Mirb.) Franco) and Pacific madrone (Arbutus inenziesii Pursh) were studied in southwest Oregon in 1990. Bedrock physical features, including bulk density, water holding capacity, and available water capacity, were examined at different depths from 1.0 to 3.0...

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...

Estimated plant water use and crop coefficients for drip-irrigated hybrid polars

Creator:: Gochis, David J.
Abstract:: Estimations of plant water use can provide great assistance to growers, irrigators, engineers and water resource planners. This is especially true concerning the introduction of a new crop into irrigated agriculture. Growing hybrid poplar trees for wood chip stock and veneer production under agronomic practices is currently being explored as...

Evaluation of evapotranspiration and irrigation performance in Oregon south coast

Creator:: Sriprisan, Sirikul (Indi)
Abstract:: This study was prompted by the need for improving the efficiency of irrigation systems at the Oregon South coastal areas. Accurate information about evapotranspiration (ET) rates is essential for maximizing the efficiency of irrigation systems. Currently, ET estimates provided by Bureau of Reclamation AgriMet Program are derived from the Kimberly...
