Response of downy brome (Bromus tectorum) and Kentucky bluegrass (Pao pratensis) to primisulfuron

Creator:: Hendrickson, Paul E.
Abstract:: Glasshouse and growth-chamber experiments were conducted to evaluate primisulfuron phytotoxicity and the influence of adjuvants on downy brome and Kentucky bluegrass. GR₅₀ (50% growth reduction) values were 0.97 ± 0.57 and 8.07 ± 1.85 g/ha for downy brome and Kentucky bluegrass, respectively. Primisulfuron was applied to downy brome and Kentucky...

Helium isotope variations in Juan de Fuca ridge basalts

Creator:: Lupton, John E., Graham, David W., Delaney, John R., and Johnson, H. Paul
Abstract:: We have measured ³He/⁴He ratios and He and Ne concentrations on a suite of 24 basalt glasses from the neovolcanic zone of the Juan de Fuca Ridge (JdFR) from 44.6°N near the Blanco Transform up to 48.0°N on the Endeavour Segment. The helium isotope ratios exhibit a clear geographic variation,...

Laboratory feeding tests on the development of gypsy moth larvae with reference to plant taxa and allelochemicals

Creator:: Oregon State University. Agricultural Experiment Station, Miller, J. C. (Jeff C.), and Hanson, Paul E.
Abstract:: The first through fifth instars of the gypsy moth were tested for development to adults on 326 species of dicotyledonous plants in laboratory feeding trials. Among accepted plants, differences in suitability were documented by measuring female pupal weights. The majority of accepted plants belong to the subclasses Dilleniidae, Hamamelidae, and...

Quantifying physical habitat in wadeable streams : surface waters

Creator:: Kaufmann, Phillip R., Levine, Paul, Robison, E. George, Seeliger, Curt, and Peck, David V.
Abstract:: We describe concepts, rationale, and analytical procedures for characterizing physical habitat in wadeable streams based on raw data generated from methods similar or equal to those of Kaufmann and Robison (in PB99-139156). We provide guidance for calculating measures or indices of stream size and gradient, sinuosity, substrate size and stability,...

Pilot experiment of forest fertilization during an outbreak of the western spruce budworm in Northeastern Oregon

Creator:: Mason, Richard R., Wickman, B. E., Paul, H. G., and Torgersen, T. R.
Abstract:: Mixed-conifer stands of grand fir (Abies grandis (Dougl. ex D. Don) Lindl., Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco), and ponderosa pine (Pinus ponderosa Dougl. ex Laws.) were fertilized with nitrogen and combination treatments of nitrogen, phosphorus, potassium, and sulfur to test their effects on trees and associated insects during...

Historical and current forest landscapes in Eastern Oregon and Washington. Part 2. Linking vegetation characteristics to potential fire behavior and related smoke production

Creator:: Huff, Mark H., Ottmar, Roger D., Alvarado, Ernesto, Vinnanek, Robert E., Lehmkuhl, John F., Hessburg, Paul F., and Everett, Richard L.
Abstract:: We compared the potential fire behavior and smoke production of historical and current time periods based on vegetative conditions in forty-nine 5100- to 13 500-hectare watersheds in six river basins in eastern Oregon and Washington. Vegetation composition, structure, and patterns were attributed and mapped from aerial photographs taken from 1932...

Long-term management effects on soil productivity and crop yield in semi-arid regions of Eastern Oregon

Creator:: Oregon State University. Agricultural Experiment Station, United States. Agricultural Research Service, Columbia Basin Agricultural Research Center, Rasmussen, Paul E., Collins, Harold P., and Smiley, Richard W.
Abstract:: Long-term experiments were started at Pendleton and Moro, Oregon in the 1930's to evaluate the effects of tillage, fertilizer, and residue management on crop productivity in non-irrigated semi-arid regions. Coupled with multi-year varietal improvement, rotation, and green manure studies, they define those practices which sustain soil productivity and improve crop...
