Information and analysis techniques for making crop selection decisions

Creator:: Bristol, Roger Dale
Abstract:: Twenty managers of large diversified irrigated farms in the Willamette Valley area of Oregon were interviewed about the economic information and analysis techniques they use when making crop selection decisions. Two community college farm management instructors, two agricultural lenders, and two certified public accountants working with farmers were interviewed about...

A contextual model for the integration of LifeKnowledge curriculum into the agricultural science and technology classroom

Creator:: Crawford, Paul Wesley
Abstract:: The purpose of this study was to evaluate a contextual model for integrating lessons from the LifeKnowledge curriculum into the agricultural science and technology (AST) course content. This was measured using the National FFA Organization’s online precept indicator which is part of the LifeKnowledge 3.0 curriculum. Ninth grade students at...

Economic feasibility of fall-calving on Oregon high desert cow-calf operations

Creator:: Nordblom, Thomas L.
Abstract:: The traditional practice on beef cow-calf ranches in the high desert region of Eastern Oregon has been to breed the cows to calve in the Spring months. Interest has been growing recently in the practice of Fall-calving; that is, breeding cows to calve in the months of October and November....

In situ measurement of the benthal oxygen requirements of tidal flat deposits

Creator:: Crook, Gene Ray
Abstract:: In situ light and dark planktonic and benthal respirometers were used to measure the oxygen requirements of Yaquina estuary water and benthal deposits. Respirometer devices were constructed so that actual conditions of mixing could be simulated and benthal deposit disturbance would be minimized. A mathematical model of a benthal respirometer...

Relationships among phosphorus soil tests, forms of soil phosphorus, and plant uptake of phosphorus for selected southwestern Oregon soils

Creator:: Doerge, Thomas A.
Abstract:: A diversity in climate, geologic parent material, and soil characteristics exist in Jackson, Josephine, Coos, and Douglas Counties of southwest Oregon. Previous field trials and soil testing results have revealed uncertainties as to the phosphorus (P) status of the soils in this area. Twenty-four sites from nine agriculturally significant soil...

Reactions of organoboranes

Creator:: Thompson, Thomas Myron
Abstract:: An examination was made of some reactions involving a transfer of carbon from boron to carbon. In the case of the reaction of a C[subscript n] alkylorganoborane with dichlorocarbene the intermediate was a C[subscript n]₊₁ chloroalkylorganoborane. Oxidation of this intermediate yielded an homologous acid (33%) and the usual alcohol (66%)....

Respiratory adaptations of two macrurousanomuran mud shrimps, Callianassa Califormiensis and Upogebia pugettensis (Decapoda, Thalassinidea)

Creator:: Thompson, Rogene Kasparek
Abstract:: Callianassa californiensis Dana and Upogebia pugettensis (Dana) inhabit estuarine mudflats and are subjected to the hypoxic conditions that prevail during tidal exposure. Metabolic responses for both these species, as indicated by critical oxygen tension, metabolic rate, and tolerance to anoxia were determined. An oxygen macro-electrode and a physiological gas analyzer...

Scrotal circumference measurements as an indicator of growth in the male beef animal

Creator:: Pirelli, Gene J.
Abstract:: Testes size as an indicator of future growth was examined in a total of 45 bull calves from spring calves born in 1978 and 1979. Scrotal circumference measurements were used as the physical indicator of testicle size in the live animal. Growth traits studied were preweaning average daily gain, weaning...

Fish and invertebrate distribution at multiple scales in Thomas Creek, Oregon : a transition from conifer uplands to agricultural lowlands

Creator:: Langshaw, Russell B.
Abstract:: Longitudinal patterns of fish and benthic invertebrate distribution and habitat use were similar in Thomas Creek, Oregon but clarity of these patterns differed. I studied fish and aquatic invertebrates simultaneously, at multiple scales, and used multivariate statistical techniques to compare responses to the same environmental conditions. Both types of organisms...
