Oregon Master Gardeners were surveyed to identify volunteer demographics, as well as familiarity with and frequency of use of current computer technology. The Oregon State University Master Gardener Program has evolved over the past 25 years, and as such so have the training needs. New demands are presently being made...
A series of field experiments conducted at the Lewis-Brown horticulture farm at Oregon
State University evaluated the performance of four preemergence herbicides in simulated
ornamental shrub beds. Two natural products, corn gluten meal (CGM) and
meadowfoam seedmeal (MFS), were used along with two synthetic products, prodiamine
purchased under the trade...
Most residential landscapes include a combination of hardscapes
(patios, decks, walkways, and driveways) and ornamental plants. As you
think about the design, construction, and maintenance of your landscape,
consider how sustainable each component is and how it could be modified to be more sustainable.
Young trees (those with a trunk diameter of less than 6 inches) can benefit greatly from regular applications of fertilizer. Research has shown that when these trees receive nitrogen fertilizer, they grow faster, develop a denser canopy, and stay green longer into the fall.
A sustainable landscape is more than exterior decoration. By using less water, fertilizer, and pesticides than a traditional
landscape, it has minimal impact on the environment. Thus, it is both aesthetically pleasing and environmentally sound.
Creating a sustainable landscape means working toward a thoughtful balance between resources used and results...
Landscapes are a valuable part of residential properties. Maintaining your landscape is important for
property values as well as aesthetic reasons. When water supplies are restricted, you can keep your
landscape healthy by developing watering priorities, applying water efficiently, and modifying your
maintenance practices.
The typical home lawn is an evolving ecosystem that gets more complex each year. At first, it consists of one or two grass species found in a typical seed mix (e.g., Kentucky bluegrass and perennial ryegrass). Over time, it evolves to three or four species that were not part of...
Many garden and landscape plants
are susceptible to one or more plant
diseases. Diseases can reduce the yield
of fruit and vegetable crops and disfigure
ornamental trees, shrubs, and
flowers.
A water-efficient landscape begins with a plan. If you are familiar with the principles of landscape design, you might want
to draw your own plan. Another option is to hire a professional to help with this critical step. In any
event, think about who will use your landscape (adults, children,...
A sustainable landscape is more than the conscious arrangement of outdoor space for human enjoyment and satisfaction. It is a landscape that uses minimal water, fertilizers, pesticides, labor, and building
materials. Creating a sustainable landscape means working toward a
thoughtful balance between resources used—both in construction and maintenance—and results gained.

It is estimated that 50-75% of Oregon vineyards cultivate at least every other alley in order to 1) reduce water stress 2) increase vineyard canopy temperatures and 3) increase nutrient availability. Because many vineyards are situated on steep hillsides, frequent tillage could result in increased soil erosion, decreased soil quality...

Archaeologists use diversity as one way of
characterizing their assemblages. Diversity refers to both
the number of artifact classes present (richness) and the
proportional representation of classes (evenness).
Numerical diversity indices measure one or both components.
Archaeologists use assemblage diversity to infer behavior
of prehistoric cultures.
Archaeological inferences about behavior...
Placental pathologies are not uncommon in dogs. For example, in primiparous bitches, the reported incidence of subinvolution of placental sites is 21% - 100%. Despite years of research in multiple species, the mechanisms regulating late gestation trophoblast behavior in the dog remain unexamined. Therefore, the objective of this study was...

Sand dunes are found along the coasts of most of the large land
masses of the world. Because of their proximity to man and his
activities, the maritime sand dunes of Europe, particularly Germany,
France, Holland and Scandinavia, have the longest history of stabilization

A survey of scholarly and popular contemporary literature
reveals two persisting stereotypes regarding the
nature of women.
First is the theory that woman is inferior to man
and that since she is the "negative" of man's masculine
nature, she cannot develop her humanity to the fullest
extent without fusion with...
A series of experiments were conducted to determine
the utilization of fibrous feeds by the rabbit. A review
of literature was performed to ascertain the results of
similar studies. The first two experiments involved

Results indicated that a 50 percent alfalfa...
Wavelet analysis is an analytical and modeling tool for optimizing sampling efficiency and accuracy, particularly in the context of designing long-term, large-scale monitoring plans. As a pattern analysis method that accommodates and preserves non-stationarity, wavelet analysis provides novel visualization and analytical capabilities for increased insight into interactions between multi-scalar heterogeneous...
Polynuclear aromatic hydrocarbons (PNAH) classified as noncarcinogens
may be photooxidized to mutagenic or toxic products by
near-ultraviolet (NUV) wavelengths of sunlight (290-320 nm). The
possibility that this represents a major degredation pathway in the
aquatic environment is of increasing concern. Large quantities of
PNAH from accidental oil spills, anthropogenic and...
The purpose of this study was to investigate the relationships
that were hypothesized to exist between the variables birth order,
family size, and parents college attendance and the dependent variable,
college graduation. The three general hypotheses tested were:

birth order...
Little empirical research has been conducted on self-gifts
as a phenomenon of consumer behavior. A review of
literature demonstrated that the phenomenon of self-gifts has
been studied from the conceptual aspect, such as self-gift
functions. Yet, our knowledge of self-gifts still remains
limited because many of the determinants of self-gifts...
Newly emerged steelhead fry (Oncorhynchus mvkiss) of hatchery and
