This study determines the optimal allocation of watershed conservation funds in the John Day River Basin, Oregon. Fund managers can use a variety of targeting schemes to allocate their limited resources. Depending on which targeting criteria is used, they may or may not be achieving the maximum environmental benefits per...
Competition for water both from within the irrigation community and from
outside interests has been a major source of conflict in the West. In the Umatilla Basin of
central Oregon, Umatilla River water is diverted to irrigate a variety of crops, while
instream flows have value in salmonid production. Historically,...
This research examines whether alternative methods of export commodity promotion and market development, such as technical training and trade servicing activities, have been successful in increasing the demand for grass seed produced in Oregon in international markets. A single equation linear input demand model and a linear model adjusted to...
Many parts of the West are experiencing substantial growth pressures that have increased the demand for water. These new demands come at a time when most of the water in the West has been fully appropriated by traditional uses such as agriculture, mining, and industry. Some attempts are being made...
Raspberries have been popular since the time of the ancient Greeks. Red raspberries are cultivated throughout the world, particularly in the Pacific Northwest region of the United States and Canada. The raspberry bushy dwarf virus (RBDV) causes significant reduction in yield and crumbly fruit in raspberries, blackberries and raspberry-blackberry hybrids....
Agricultural practices influence the nutrient dynamics of soil and plants, which may take more than a decade to be expressed in the drylands. The nutrient supplying capacity of soil is a crucial component of sustainable agriculture, and hence, this study can play an important role in policy making for the...
The closed insulated pallet system (CIPS) was evaluated for growth, yield, and
fruit quality of tomato genotypes with determinate growth habit. Plants were irrigated
with several levels of sodium chloride (NaCl) salinized water. Tomato growth and yield
were significantly greater in CIPS than in conventional surface-irrigated containers,
regardless of irrigation...
To protect and restore environmental quality, efficient and effective conservation policies are needed. Designing policies require a sound understanding of the contributions of natural endowments to economic vitality, and the performance and impacts of conservation programs. This dissertation consists of three essays, and addresses several issues relevant to these two...
Ponderosa pine (Pinus ponderosa) and lodgepole pine (Pinus contorta var. murrayana) forests of south-central Oregon have been extensively researched over the last century. However, little information has been reported on overstory composition and stand structure shifts associated with fire exclusion within inter-mixed ponderosa pine and lodgepole pine stands of the...
