Lateral diffusion of S-ethyl N-ethylthiocyclohexanecarbamate
(cycloate)¹ is essential for satisfactory weed control with injection
type incorporation in sugar beet (Beta vulgaris Linn.) production.
Previous field experience with injection incorporation has indicated
that sufficient lateral diffusion for satisfactory weed control has not
occurred under all field conditions. Researchers who have been...
An ionization chamber was constructed, using a fiberglass wall
sphere, for the purpose of measuring background radiation. The
system consists of the fiberglass wall chamber, 38.85 liters in
volume, air filled, not sealed, used in conjunction with a precision
capacitor, nulling voltage supply and electrometer. It was calibrated
against a...
Studies were conducted on artificially infected susceptible and
resistant barley varieties in an attempt to determine the effect of
barley yellow dwarf virus on the growth and development of these
plants. A resistant and a susceptible variety were infected at four
stages of growth and harvested at two stages. Roots,...
The purpose of this study was to determine whether or not a
significant difference existed between Oregon community college
transfer students and native students at Oregon State University with
respect to academic achievement, persistence, and graduation.
Two groups of students were selected for observation. The
first included all of the...
The rainbow trout population in Elder Creek, Oregon was
studied between June 1965 and November 1966. The physical characteristics
of the stream during the summer season were described.
Rainbow trout were captured in each of three sections on the stream
by electrofishing and were tagged and measured. Population size,
mortality,...
This document contains a summary of changes in administrations and actions taken by the Pacific Marine Fisheries Commission in 1963 and 1964, as well as an update for the status of various fisheries.
These short reports are intended to inform the public, fishing industry, sportsmen, and fisheries scientists of research conducted by the Fish Commission. Reports will be published from time to time as studies are sufficiently complete. Most of the reports provide biological evidence upon which measures are based to enhance and...
