The effect of direct application of liquid fertilizers on the germination, emergence and seedling growth of wheat (Triticum aestivum L.)

Creator:: Venegas, Cesar Rolando
Abstract:: The effect of four basic liquid fertilizers: Solution 32, 10-34-0-.9, Thio-Sul, and Potash solution; and one commercial liquid fertilizer, Feast 9-18-9, on germination, emergence, and seedling growth of wheat (Triticum aestivum L.) were evaluated under laboratory, greenhouse, and field conditions. Experiments included: 1) preliminary study of basic fertilizer sources to...

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...

Effect of nitrogen and water stresses during tillering and grain- filling in wheat

Creator:: Ashraf, Muhammad, 1952-
Abstract:: The CERES-Wheat Crop Growth and Development model treats temperature, nitrogen and water stresses as limiting factors. For each day the model calculates a stress index for temperature, N and water, compares the magnitude of the indices, and then adjusts the calculated daily potential growth using the index of the most...

Ryegrass fluorescence expression during three generations of seed increase and its heritability among half-sib families

Creator:: Floyd, Donald J.
Abstract:: Seedling root fluorescence (SRF) has been used as a test in the USA since 1941 to discriminate Italian ryegrass (Lolium multiflorum Lam.) from perennial ryegrass (L. perenne L.). Generally, roots of Italian ryegrass fluorescece when exposed to ultraviolet light, while roots of perennial ryegrass do not. Presence of fluorescent seedlings...

Water injection into the seed zone as an aid to emergence of dryland cereals

Creator:: Estes, James Patrick
Abstract:: An adequate stand at the optimum time is an important factor affecting potential yield and soil erosion control. However, obtaining adequate stands of fall planted winter wheat in the dryland areas of the Pacific Northwest is often complicated by marginal seed zone soil moisture. The purpose of this laboratory study...

Physical and physiological seed characteristics influencing wheat stand establishment

Creator:: Ahmad, Shahbaz
Abstract:: Rate of emergence is an important character for stand establishment. Ability of wheat seeds to germinate and emerge rapidly under different climatic conditions may be regulated by physical and/or physiological characteristics. Seeds of 26 wheat varieties representing five classes were produced in two different environments (Moro and Corvallis, OR). Seed...

The effect of precipitation variation on soil moisture, soil nitrogen, nitrogen response and winter wheat yields in eastern Oregon

Creator:: Glenn, D. M. (David Michael)
Abstract:: The semi-arid regions of the Pacific Northwest are characterized by a high degree of annual temperature and precipitation variation. As a result of this climatic variation, dryland nitrogen fertilizer trials on fallow- ,wheat rotations typically demonstrate a variable response. Wheat growers in the area must not only cope with this...

Measuring wind speeds for small turbine sites

Creator:: Oregon State University. Extension Service and Floyd, Don
Abstract:: About 2 percent of the solar energy reaching earth is converted to wind energy. Surface winds have the potential to supply about 30 times the total energy consumed in the United States. Achieving this potential on a household level is a feat

Seasonal relationships between dissolved nitrogen and landuse/landcover and soil drainage at multiple spatial scales in the Calapooia Watershed, Oregon

Creator:: Floyd, William C.
Abstract:: The Calapooia River, a major tributary of the Willamette River in western Oregon, is a watershed typical of many found in the Willamette Basin. Public and private forested lands occur in the steep Upper Zone of the watershed, mixed forest and agriculture lands are found in the Middle Zone, and...
