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,...

Potato (Solanum tuberosum L.) tuber quality response to a transient water stress

Creator:: Eldredge, Eric P.
Resource Type:: Dissertation
Full Text:: turgor. Measures of turgidity and leaf water potential are good indicators of potato plant water status

Effects of water stress on phenology, physiology, and morphology of containerized Douglas-fir (Psuedotsuga menziesii (mirb.) Franco) seedlings

Creator:: Khan, Shafiqur Rehman
Abstract:: Approximately 3-4 month-old containerized Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings (seed zone 262 and 271) were subjected to 6 moisture stress treatments (65, 53, 41, 29, 17 and 7% soil water content by volume of dry soil) starting July 4 to September 22, 1991 at Forest Research Laboratory's greenhouse at...

Fallow water retention and wheat growth as affected by tillage method and surface soil compaction

Creator:: Schillinger, William F.
Abstract:: No-tillage winter wheat (Triticum aestivum L.) grown in a wheat-fallow cropping system has consistently produced lower grain yields than conventionally tilled soils in the semiarid Pacific Northwest. A 2-year study was conducted in a long-term tillage trial at Moro, OR to determine factors responsible for differences in wheat growth and...

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...

Growth, yield and water use of rainfed wheat and maize influenced by tillage and fertilizer in Pothwar, Pakistan

Creator:: Ali, Safdar
Resource Type:: Dissertation
Full Text:: sand (Typic Ustipsamment) at Ludhiana, India, that better root growth and plant water status with

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...

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...
