Response of field corn to irrigation, plant population, and nitrogen on soils of the Willamette catena

Creator:: Andersen, Jimmie Lee
Abstract:: The purpose of this study was to make a preliminary investigation of the productivity of some of the soils within the Willamette catena under different systems of soil management. The study was carried out at four experimental sites near Corvallis, Oregon, during the 1962 growing season. The soil at each...

The reactions of picloram and 2, 4-D with montmorillonite clays and soils

Creator:: Kuo, Eugene Cheng-yen
Resource Type:: Dissertation

Calibration of a theoretically derived relationship between pan evaporation and evapotranspiration

Creator:: Salgado, Eduardo A.
Abstract:: Theoretical derivations to describe pan evaporation, E[subscript p], and evapotranspiration, ET[subscript r], were developed based on a flow equation expressed as the product of the driving force for vapor between the evaporative surface and a plane of reference times a conductivity coefficient of vapor through air. Under the assumptions of...

Effects of tillage systems on nitrate-nitrogen accumulation and soil structure

Creator:: Avcin, Abdulkadir
Abstract:: Effects of different tillage systems on nitrate-nitrogen accumulation in a 120 cm profile and on soil structure in the top 30 cm of the profile were studied under a fallow-wheat rotation. Treatment effects on nitrate-nitrogen, soil moisture and soil aggregation were measured. Fallow tillage treatments consisting of bare fallow, stubble-mulch...

Factors associated with stand establishment and subsequent grain yield of seven wheat cultivars and selected progeny (Triticum aestivum, L em thell) when grown under three diverse environments

Creator:: Vahabian, Mohammad Ali
Resource Type:: Dissertation

Early macronutrient uptake and partitioning in Glycine max L. Merr

Creator:: Schuttler, Patti L.
Abstract:: Soybeans were grown in hydroponic solutions and in perlite to devise procedures to measure plant mineral accumulation and solution depletion over time. Electron emission spectrometry and micro-Kjeldahl-autoanalyzer analytic techniques were used to monitor mineral content of individual plants and their corresponding solutions. An automated computer assisted system of converting raw...

The physiology of Picea grafts

Creator:: Beeson, Richard C.
Resource Type:: Dissertation

Stratigraphy and sedimentology of the Cretaceous Nanaimo group, Saltspring Island, British Columbia

Creator:: Hanson, William Bruce
Abstract:: Clastic sedimentary rocks of the Nanaimo Group on Saltspring Island, British Columbia are Late Cretaceous in age, overlie a deformed and intruded Paleozoic basement complex, and consist of eight formations. These eight formations, from oldest to youngest, are the Comox, Haslam, Extension-Protection, Cedar District, De Courcy, Northumberland, Geoffrey, and Spray...
