The influence of chemical and biochemical properties on the herbicidal efficiency of 3-cyclohexyl-5, 6-trimethylene uracil and 2-bromo-6'T-butyl-o-acetotoluidide

Creator:: Mackenzie, John William
Abstract:: Application of herbicides to the soil has become an important factor in the production of row crops. Economic production of sugar beet (Beta vulgaris), an important row crop, requires efficient methods of weed control. Two experimental herbicides, 3-cyclohexyl-5,6-trimethylene uracil (DP634) and 2-bromo-6't-butyl-o-acetotoluidide (CP32179), had shown promise in sugar beet screening...

Response of feed lot heifers to certain exogenous hormones

Creator:: Caster, John Eugene
Abstract:: Some effects of hormone treatment on feedlot heifers were studied. The treatments were 15 mg diethylstilbestrol (DES) implant, Synovex H implant, .25 mg oral melengestrol acetate (MGA) per head per day, and .40 mg oral MGA per head per day. One hundred heifers, 20 to each treatment, were used. All...

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...

Vegetation changes of communities containing medusahead (Taeniatherum asperum (Sim.) Nevski) following herbicide, grazing, and mowing treatments

Creator:: Turner, Robert Bruce
Abstract:: Studies were conducted from 1962 to 1966 to investigate the effectiveness of several practices in manipulating medusahead (Taeniatherum asperum (Sim. ) Nevski) infested and/or dominated ecosystems by releasing competition in favor of perennial grasses. Several herbicide treatments were evaluated for selective control of medusahead and cheatgrass (Bromus tectorum L. )...

Seasonal cattle and sheep diets on Festuca arundinacea-Trifolium subterraneum and Lolium perenne-Trifolium subterraneum pastures in western Oregon

Creator:: Bedell, Thomas E.
Abstract:: Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum) pastures in western Oregon during the spring and summer periods of 1964 and 1965. Esophageal-fistulated Willamette ewes and Hereford and Hereford-Angus yearling cattle were grazed separately on each pasture mixture...

The interaction of polylysine with DNA as studied by polarization of flurescence

Creator:: Evett, Jay Fredrick
Abstract:: A fluorescent dye, 1-dimethylaminonaphthalene-5-sulfonyl chloride (dansyl chloride), was covalently bonded to polylysine. The dansyl tagged polylysine was complexed to DNA by gradient dialysis. The polarization and intensity of fluorescence of the dansyl and the turbidity of the complex were measured as a function of salt concentration for a variety of...

Distribution of recent foraminifera in relation to estuarine hydrography, Yaquina Bay, Oregon

Creator:: Manske, Douglas Charles
Abstract:: The foraminiferal population of Yaquina Bay was investigated to attempt a correlation of seasonal changes in the hydrography with observed changes in the faunal distribution patterns. The results are based on data from two spatial surveys conducted in July 1966, and late February and March, 1967. The hydrography of Yaquina...
