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...

The effect of water injection at seeding in dry soil on the germination and growth of winter wheat (Triticum aestivum L.)

Creator:: Noori, Fariborz
Abstract:: Stand establishment plays a significant role in the development and yield of winter wheat (Triticum aestivum L.). Availability of soil moisture to the germinating seed is one of the most critical factors affecting stand establishment. Water injection is a method of applying supplemental moisture to the soil in direct contact...

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...

Water relations and associated morphology of conditioned Douglas-fir and jack pine seedlings subjected to periods of drought stress

Creator:: McClain, K. M.
Abstract:: Significant post planting mortality of young conifer seedlings often occurs on drought prone sites because seedlings fail to either establish, or maintain favourable water relations. Survival is contingent upon growth which occurs when turgor pressure is above a threshold level. Since growth after planting is influenced by nursery cultural practices,...

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...

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...

Summary report to assist development of ecosystem flow recommendations for the Coast Fork and Middle Fork of the Willamette River, Oregon

Creator:: Gregory, Stanley V., Ashkenas, Linda, and Nygaard, Chris
Abstract:: Introduction The Willamette River Flow Project The Nature Conservancy (TNC) and the U. S. Army Corps of Engineers (USACE) are collaborating on a project to determine environmental flow requirements for the Willamette River and its tributaries and to design and test alternative flow releases from the dams that can meet...

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...
