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...

Water use characteristics of ten newly established cool-season turfgrass species

Creator:: Blankenship, Tod M.
Abstract:: Water use restrictions are continuing to have an impact on the way turf is managed today and will be managed in the future. The objective of this research was to evaluate the irrigation requirements of ten newly established cool-season turfgrass species maintained under two different mowing height and nitrogen fertility...

Height-related trends in structure and function of Douglas-fir foliage

Creator:: Woodruff, David R.
Abstract:: This dissertation investigated the impacts of tree height upon a range of physiological and structural characteristics of Douglas-fir foliage; relationships between structural and functional trends with height; and compensatory mechanisms that mitigate height-related growth constraints. Height-related trends in foliar physiological and anatomical characteristics were examined both within trees as well...
Resource Type:: Dissertation
Full Text:: dissertation is the first to evaluate the effects of the gravitational component of water potential on the

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...

Impact of exotic Ponderosa pine (Pinus ponderosa Doug. ex Laws.) plantations on water resources in northwestern Patagonia, Argentina

Creator:: Licata, Julian A.
Abstract:: Exotic ponderosa pine (Pinus ponderosa Doug. ex Lawson) plantations are being planted within the natural distribution area of cordilleran cypress (Austrocedrus chilensis (D.Don) Pic. Ser. et Bizzarri) in Patagonia, Argentina. The productivity of these exotic plantations is much greater than that of native forests, suggesting greater water use. Before these...

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...

Faidherbia albida Water Use and Impacts on Teff Growth in a Sub-humid Environment in Mojo, Ethiopia

Creator:: Krampien, Jeannette T.
Abstract:: Faidherbia albida is a widely used tree species in sub-Saharan Africa, promoted for use in parkland agroforestry systems based on reduced competition with crops during the rainy season from its reverse leafing phenology and positive effect on soil fertility. Increases in growth and yield have been reported for crops such...

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.

The influence of antidesiccants on field performance and physiology of 2+0 ponderosa pine (Pinus ponderosa Dougl.) seedlings

Creator:: Vera-Castillo, J. A. Gil
Abstract:: This thesis research examines the effects of film-forming antidesiccants applied to dormant pondexosa pine (Pinus ponderosa Dougl.) seedlings after being lifted and to actively growing seedlings. The basic proposition was that antidesiccants would have a positive effect on reducing water loss in ponderosa pine seedlings. In order to evaluate the...

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...
