Management factors used for studies on potato scab
control were evaluated for their effect on tuber russeting
and related biochemical and anatomical parameters
during 1971 and 1972.
Russet Burbank potatoes were irrigated in 1971 to
maintain high available soil moisture (between 90% and
field capacity) for 0, 3, 6 and...
Seed yield in perennial ryegrass is the product of yield components
that develop during the life of the plant. Crop yield potential is
defined by the number of fertile tillers, spikelets per spike, and
florets per spikelet. It has been shown that perennial ryegrass
realizes only a small percentage of...
Hard Fescue (Festuca longifolia Thuill.) has potential for in
creased turf use but does not respond well to normal seed production
management practices in Oregon. Field burning (the normal residue
management practice) results in reduced seed yields in commercial hard
fescue seed production fields but stimulates seed production in Chewings...
Studies were conducted to determine the uniformity of three
commercial seed lots of ryegrass (Lolium spp.) and the effects of lot
size on lot uniformity. Individual bag-samples were taken from each
seed lot. Factors considered were percentage purity, annual ryegrass,
perennial ryegrass, weed, other crop, inert matter, and germination.

This lesson plan is designed to provide leaders in livestock and horse clubs with sufficient resource material on plant identification and evaluation. Leaders may then introduce plant identificat·ion and evaluation to members. Through the activities suggested and innovative use of presentations by club members, this lesson plan can broaden activities...

Samples of Russet Burbank and Kennebec seed potatoes
used by Oregon growers were grown in replicated plots at
Klamath Falls, Prineville and Corvallis. Observations
were made of total yield, yield of U.S. No. 1 tubers and
number of stems produced per plot.
Total yields of the Russet Burbank variety were...
Soils representative of several landscape units in the H. J.
Andrews Experimental Forest, Western Cascade Range, were sampled,
analyzed, and tentatively classified. Genetic inferences were
drawn relating soils to landscape position and other factors of soil
formation. Descriptive information and nutrient capital data were
provided to support ecosystem modelling efforts...
Snowbrush (Ceanothus velutinus), red alder (Alnus rubra), and
bitterbrush (Purshia tridentata) are three important nitrogen- fixing
nonleguminous species. They commonly grow in association with
commercially important conifers in western United States and conceivably
could be utilized to add nitrogen to forest ecosystems. Nitrogen
15 gas was used to study nitrogen...
Field study with 5 tall fescue genotypes treated at the vegetative
growth stage, with 0, 0.28, 0.56, and 0.84 kg/ha of mefluidide
was initiated in July, 1980. The regrowth of these plants were again
treated at the booting growth stage in April, 1981, with the same
rates of mefluidide as...
