The objective of this thesis is to assess four winter feeding programs of spring-calving brood cows that may improve profitability to ranching operations of the Harney Basin, Oregon. The four feeding strategies include strip grazed rake-bunched hay, supplemented range grazing, strip grazed meadow pasture, and baled hay feeding. These first...
Farm machinery continues to increase in its importance to the agricultural sector. Depreciation, the decline in value of a durable asset over time, represents one of the largest costs of agricultural production. The general objectives of this study were to update and expand the number of Remaining Value (RV) functions...
Local government officials and county planners may find descriptive information concerning the economic structure of each Oregon county useful for planning for future economic development. Specifically, citizens of counties and planning districts need to know whether industries in their area are growing or declining and in which industries a comparative...
The "unusual" behavior of agricultural land prices is the subject of considerable debate and controversy and is the object of this research. There is little doubt that land prices have been increasing steadily since 1959 and dramatically throughout the decade of the 1970's. However, there is widespread disagreement among economists,...
Policy decisions in fishery management are becoming increasingly
complex and difficult. This is especially true for the salmon fisheries
where policy outcomes affect the productivity of the salmon
resource and the subsequent well-being of commercial fishermen, charter
boat operators, Indian fishermen, and sport anglers. The objective
of this study was...
A Turfgrass Information and Decision Support System (TIDSS) was developed by international collaborators. In this project, an efficient and effective web-based information system, composed of a Turf Content System (TCS), a Turf Resource System (TRS), and the supporting tools, was developed to support the cooperative efforts. A comprehensive schema of...
A computerized ranch simulation model of an eastern Oregon cattle
ranch was tested for its ability to evaluate the economics of public
rangeland improvement practices. The model was used to estimate
likely impacts of various public policy alternatives for rangeland
improvement on the relative profitability of a 400 mother cow...
Centuries of continuous grain cropping in northern Africa have
reduced N levels in soils to a degree such that agricultural production
is now largely dependent upon nitrogen fertilizer. Through the
identification of highly effective legume and Rhizobium strain combinations,
the production of protein-rich livestock forage and green
manure can be...
