Response of Canada milkvetch (Astragalus canadensis var. mortonii (Nutt.) Wats.) to range and forest improvement practices in Northeastern Oregon

Creator:: Wood, Benjamin William
Abstract:: The response of Canada milkvetch (Astragalus canadensis var. mortonii) to range and forest improvement practices was studied on a stand of mixed-coniferous forest which was clear -cut and burned in 1963 and 1964, respectively. The field studies were conducted on the Hall Ranch of the Eastern Oregon Experiment Station during...

Vegetation and animal responses to grazing crested wheatgrass at three intensities and two seasons in southern Idaho

Creator:: Sharp, Lee Ajax
Abstract:: Land useable for livestock grazing in the western United States is diminishing because of spreading municipalities, irrigation developments, highway construction, recreational demands and withdrawals. Concurrently, the demand for livestock and livestock products is increasing because of a rapidly growing population. As a result, production from the grazing land that remains...

The influence of variety, plant population and planting date on corn silage production

Creator:: Samphantharak, Krisda
Abstract:: The influence of variety, plant population, and planting date on corn silage production was studied at Hyslop Agronomy Farm, Corvallis, Oregon. The corn plants were grown under irrigation with 300 pounds per acre of 16-20-0 (N-P₂0₅-K₂0) and 240 pounds of urea, providing a total nitrogen application of 158 pounds per...

Effects of seeding and grazing on a clearcut-burn in a mixed-coniferous forest stand of the Wallowa mountain foothills

Creator:: Pettit, Russell Dean
Abstract:: Research was conducted in a mixed-coniferous forest stand that was clearcut, burned, and seeded in order to study early plant succession, grazing influences on native and introduced species, big game use, and environmental relationships vegetation, animal, and environmental research was carried out from 1965 to 1967 in three, five-acre exclosures...

Influence of range improvement practices on composition, production, and utilization of Artemisia deer winter range in central Oregon

Creator:: Urness, Philip J.
Abstract:: Recent emphasis on range improvement of sagebrush-bunch-grass types in Oregon has underscored the need for better understanding of their importance to deer winter range management. The objectives of this study were to evaluate the impact of various sagebrush control practices on the composition, production, and utilization of deer forage plants...

The biology and behavior of the alkali bee Nomia melanderi Cockerell (Hymnoptera: Apoidea)

Creator:: Hackwell, Glenn Alfred
Abstract:: Nomia melanderi Cockerell is one of the most efficient pollinators of alfalfa in Eastern Oregon. Emergence begins in June, usually reaches its peak in early July, and may continue into early August. Male emergence precedes female emergence by four or five days. For the first few weeks of this time,...

The examination of seed yield potential in certain genotypes of birdsfoot trefoil (Lotus corniculatus L.)

Creator:: Bresciani, Juan Carlos
Abstract:: In the last 30 years, birdsfoot trefoil (Lotus corniculatus L. ) has been recognized as a great potential source of forage. Since the 1930's, many studies have been reported in relation to birdsfoot trefoil characteristics, including some directly related with the association between seed yield and its components. The purpose...

Some factors that affect pollination and seed formation in alfalfa, Medicago sativa L

Creator:: Bradner, Norman Richard
Abstract:: The objectives of this study were (a) to measure the amount of cross-pollination caused by three bee species at 10, 20 and 40 rods distance from a foreign pollen source, (b) to measure the effects of bee species, planting pattern and season on broad sense heritability estimates for seed yield...

Phytosociology of the ponderosa pine type on pumice soils in the Upper Williamson River Basin, Klamath County, Oregon

Creator:: Volland, Leonard A.
Abstract:: The study was conducted over approximately 191,000 acres in central Klamath County, Oregon. The research had three objectives: first, to describe and classify the seral and near-climax vegetation by using polyclimax principles; secondly, to determine the southern extension of five plant associations and one plant associes as previously described by...
