Leaf stress in corn, beans, and tomatoes under optimum soil moisture conditions

Creator:: Nilsson, Colin Wayne
Abstract:: Under adverse soil moisture conditions a critical water stress or water potential develops in the plant and productivity is reduced, or in extreme cases, terminated. Research to determine the soil moisture status for maximum production of specific crops has been conducted for decades. The results have done much to increase...

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...

Physiological impacts of groundwater and surface water application on desert graminoids of different geographic origin

Creator:: Abdallah, Mohamed (Mohamed Ahmed B.)
Abstract:: Desert plant communities are among the most sensitive to changes in soil water conditions. In areas with shallow aquifers, it is important to understand both the effects of groundwater alterations on vegetation and how changes in surface-soil water affect plant water uptake. Studies in arid environments have evaluated the effect...

Using infrared canopy temperature and leaf water potential for irrigation scheduling in peppermint (Mentha piperita L.)

Creator:: Gallardo, Ivan T.
Abstract:: Several methods of infering plant water stress for irrigation scheduling are based upon measurements of the environment in which the plants grow. These measurements include parameters such as soil water content, air temperature, pan evaporation and incident radiation. It is hypothesized that improved estimates of plant water deficit can be...

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...

Response of 'Pinot noir' grapevines to a perennial ryegrass cover crop and irrigation in the Willamette Valley

Creator:: Wilson, William D. (William Donald), 1955-
Abstract:: A perennial grass grown in strips between the rows of grapevines, with a bare soil herbicide strip under the rows of vines, is a common form of vineyard soil management. Irrigation, though not practiced for grape culture in western Oregon at this time, could be used to supplement the soil...

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...

The use of off-stream water developments and various water gap configurations to modify the watering behavior of grazing cattle

Creator:: Clawson, Jeffrey E.
Abstract:: Two case studies were designed to study the effects of using off-stream water developments and water gap configurations to modify watering behavior of cattle. There were two objectives: 1) to evaluate an off-stream water source to reduce water quality impacts of grazing cattle on a mountain riparian zone during summer...

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...

Characteristics of pools used by adult summer steelhead (Oncorhynchus mykiss) in the Steamboat Creek Basin, North Umpqua River, Oregon

Creator:: Baigun, Claudio Rafael Mariano
Abstract:: This study examined features of deep pool (>0.8 m mean depth) used by adult summer steelhead in Steamboat Creek (1991-1992). Steamboat Creek had a heterogenous thermal profile, with some segments exceeding preferred temperature of steelhead. Deep pools were scarce (4% of the total habitat units) and 39% of them were...

Heifer performance and drought and grazing effects on flood meadow vegetation

Creator:: Nixon, David Eugene, 1963-
Abstract:: Native flood meadows are important for hay production and winter feeding areas in many western states. With the introduction of meadow foxtail (A lopecurus pratensis L.) and other new species, the botanical composition of the meadows has been steadily changing. With shifting priorities occuring on public lands, these flood meadows,...

Estimation of leaf area index and simulation of evapotranspiration for intensively managed Douglas-fir forests

Creator:: Rogers, Nicole S.
Abstract:: Understanding the tradeoff between water use and productivity is critical for modeling growth of intensively managed Douglas-fir forests in the Pacific Northwest. Evapotranspiration is closely linked to carbon dioxide intake during the process of photosynthesis. However, summer drought characterizing the growing season in this region imposes a limit on carbon...
