The passing of the 21st Amendment to the United States Constitution has given to individual states the authority to regulate the sale, distribution and taxation of domestically produced wines, and made the wine trade potentially significant as a means of augmenting state revenues. In the state of Oregon, table wines...
Yield reductions due to competition of weeds with crop plants
can be extremely important. Early weed competition can be as important
in reducing crop yield as weed competition for the entire
season.
The objectives of this study were (1) to determine the weed
control achieved by narrow row-cropping patterns, (2)...
Concern over the apparent disparity between the farm use value
and current market value of property in agricultural areas continues
to remain a source of concern in many areas. This concern has
intensified in recent years, particularly in those agricultural areas
situated near urban centers and recreational areas.
The main...
An average stand diameter yield table and a diameter growth
per decade table are presented for unmanaged stands of quaking
aspen in southwest Colorado. The yield table presents yields per
tree for the following utilization standards: 1. total cubic-foot
volume minus the stump, 2. cubic-foot volume to a 4-inch top,...
An understanding of the dynamics of individual tree and stand
growth, development, and structural patterns during the immature
formative years of a commercial species is essential to determine
correct thinning practices necessary to attain desired objectives.
This study compared a natural, medium-site Douglas-fir stand
and an adjacent similar stand released...
An experiment was conducted to determine if selection from
standardized litters would be effective in separating lines of mice
selected for increased and decreased litter weight at 14 days of age,
and if response to selection on this maternally influenced trait could
be accurately predicted.
Data were collected on litter...
The quality and cost of wood particle composites are substantially
determined by how the adhesive that bonds the composite is
distributed on the particles. Distribution of the adhesive is controlled
by the method of application. Currently the adhesive is applied by
spraying it onto the particles. It was hypothesized that...
Difficulties have been encountered in gluing some Southeast
Asian woods using phenolic resin. Extractives in veneers from the
trade groups yellow, white, and red meranti (Shorea, Parashorea,
and Pentacme spp. ), keruing (Dipterocarpus spp. ), and kapur
(Dryobalanops spp. ) were suspected to be able to modify resin cure
and...
An investigation was conducted on factors influencing sex ratio in Eurytemora. Fifteen generations of brother/sister mating have produced family lines with a high proportion of either males or females of Eurytemora affinis. On this basis, a polygenic mechanism of sex
determination is proposed for E. affinis. Laboratory experiments on the...
The red-band trout is native to many small, isolated streams in southeastern Oregon. A study of the red-band population of Three-
mile Creek and Reservoir was conducted from August 1973 to June 1975. Data were collected concerning population size, age composition,
growth, biomass, recruitment, fecundity, and habitat. During the spring...
The fundamental objective of this analysis was to isolate and
identify the factors governing the demand for domestically produced
rainbow trout in a representative west coast market, and assess the
impact on that demand, if any, of the introduction of pansize salmon.
The approach taken in this market demand study...
Past research has implied that differences in blender performance
between commercial and laboratory particleboard blenders
may not be attributed to resin distribution between screen fractions,
as is commonly believed in the industry today, but to which particles
within a screen fraction have resin and which do note
To test this,...
The relationships of several wood quality traits with seed origin
and phenological characteristics, measured at a young age, were
tested from six seed sources in a young Douglas-fir (Pseudotsuga
menziesii (Mirb.) Franco) provenance plantation. The wood quality
traits measured were wood density, uniformity of wood density,
percentage latewood, fiber length,...
The study evaluates the use of Competitive Stress Index (CSI) as a
quantitative measure of stand density in a young-growth Douglas-fir
stand in Western Oregon which had been subjected to various thinning
regimes. Operational applications of the index are examined and new
methodologies presented for the analysis of tree and...
This study is an economic analysis of enrollment demand for
graduate education at Oregon State University as well as in the United
States. For the analysis of Oregon State University data on new
graduate enrollment, data were obtained for 27 academic departments
with 10 observations per department. The most important...
Four winter and four spring barley cultivars along with their F₁
hybrids were grown on the Hyslop Agronomy Farm near Corvallis, Oregon,
a high rainfall site (over 1000 mm annually) located in the Willamette
Valley. The experiment consisted of four replications. Ten seeds of
each F₁ and parents were seeded...
This research has addressed an area of outdoor recreation economics which presents difficulties in estimation of demand and valuation. The focus was on visitors to three Columbia River fish
hatcheries, and the net benefits realized from partaking in the recreational/educational experience which fish hatcheries offer. Three characteristics of the recreation...
The purpose of this study was to analyze the effect of the use
of vocationally - oriented applications on the achievement and attitude
of community college beginning algebra students. The applications
were chosen to be representative of problems encountered in
a variety of occupations. They were in contrast to the...
