Birdsfoot trefoil (Lotus corniculatus L.) is a popular perennial, non-bloating forage legume used for pasture, hay and silage throughout the temperate regions of Europe, Asia Minor, North Africa and North and South America. It is regarded as the most morphologically and biochemically variable species in the genus. Research investigating the...
There is no information available on water management of birdsfoot
trefoil grown for seed. Information is also not available describing how to
minimize seed losses due to shattering in order to obtain consistently high
birdsfoot trefoil seed yields. The objectives of this research are to: (i) quantify
crop water use,...
Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover
seed yields can be highly variable and low in western Oregon. The objectives of
this study were to: i) determine crop water requirements and supplemental
irrigation timing, and ii) quantify the effects of soil and water status on
inflorescence...
Subterranean clover (Trifolium subterraneum L.) seed production
practices in Oregon are different from those in Australia.
There, seed is produced on fields which are managed primarily for
forage. In Oregon, seed fields are managed for seed as the primary
product and forage is of secondary concern.
Some sheep grazing is...
The study was conducted to identify variables, from
among the theory related and demographic/biographic variables
included in the study, which were able to discriminate
between groups of male and groups of female freshmen
who differed in their level of self-actualization.
Five hundred and forty freshmen (277 males and 263
females)...
The purpose of this study was to determine if
students' school-related attitudes are significantly
affected by teacher classroom discipline management based
upon concepts contained in Judicious Discipline: A Constitutional
Perspective for School Rules (Gathercoal, 1986).
The data relative to student school-related attitudes
of elementary, middle, and high school students toward...
The purpose of this study was to assess the attitudes of teachers at the
elementary, middle, and high school levels toward student rights and
classroom management. Specifically this study was designed to analyze the
effect Judicious Discipline: A Constitutional Perspective for School Rules and
Decisions had upon teacher attitudes toward...
Many studies suggest that weedy plant species are most successful when
soil nitrogen in abundant. Consequently, I used soil nitrogen manipulations to
determine if altering nitrogen would affect the establishment of both weedy and
native plant species in a western Oregon wetland prairie. In two studies, we
added carbon amendments...
The evolutionary relationship between Frankia and actinorhizal plants was evaluated
by reconstructing molecular phylogenetic trees from nifH, 16S rDNA, and rbcL
nucleotide sequences. Subgroupings in Frankia phylogenetic trees reconstructed from
nifH and from 16S rDNA sequences were consistent in terms of plant origins of Frankia
strains. Although the branching order...
