Producing fruit in alternate years (A-Y) in Thornless Evergreen blackberries is economically feasible and a horticulturally sound management practice. The cultural advantages are: less labor is required; pesticide and irrigation requirements are reduced; pesticide timing and application are improved; maturity of fruit is hastened; and mechanical damage to new canes...
Earlier papers by Brown [1973] and Brown and Beattie [1975] showed, for the common case of positively interrelated explanatory variables, that the ridge regression estimator of Hoerl and Kennard [1970] gave much larger bias and mean square error (MSE) for models with unlike signs. To avoid this excessive bias and...
This report summarizes project progress in FY 1974. Activities were directed entirely at completing the fourth and final phase of work started in 1971, i.e., to survey groundfish resources on the continental shelf off Oregon between the Columbia River and Cape Blanco. Objectives of the survey were to obtain estimates...
The analytical method employed for the Total Organic Carbon (TOC)
project in the Geochemical Ocean Sections Study (GEOSECS) is described
in detail. The method generally follows that of Menzel and Vaccaro as
modified by several subsequent workers including the GEOSECS group at
Oregon State University which carried out the TOC...
This report consists of tables summarizing data regarding streams receiving hatchery-reared rainbow trout since 1952. It includes data such as sources, sizes of fish, and water temperatures at the planting sites. It also averages data from creel reports from 1965-1972.
Almond growth has recently been initiated in Mexico in the effort to realize commercial production. This research paper is an evaluation of the physical environment conditions which favor almond production and an attempt to apply them to Mexico. It is shown that areas in the Northwest and Central Plateau are...
Razor clam diggers were sampled from March through September on Clatsop beaches for number and age composition of the clams harvested and the distribution and number of diggers. Data from beaches south of Tillamook Head was collected as time permitted. Samples of razor clams from Clatsop beaches were collected for...
The Upper Kiamath Valley and Klamath Marsh areas of
south-central Oregon comprise the summer range for a modern
system of transhumance agriculture. Approximately 72,000
head of cattle are annually trucked from these relatively
small Kiamath pastures to winter pastures scattered throughout
the Sacramento Valley. Field research indicates that
the development...
