Field trials of weed control research on several vegetable crops are reported in this summary. Unless otherwise indicated these trials were conducted at the Vegetable Crops Research Farm at Corvallis. Soil type at this location is a silty clay loam and all plots were sprinkler irrigated as needed to provide...
In early May of 1969 a corn screening trial was established on the East Farm Experiment Station near Corvallis. The purpose of the trial was to determine the effectiveness and safety of a series of experimental herbicides.
The following summaries of results from experimental work with herbicides in horticultural crops cover work completed in 1967. Crops included are bush snap beans, red beets, direct seeded broccoli, cucumber, summer squash, strawberries and nursery rhododendrons. In general, weather conditions were warmer and drier than usual during the 1967 growing...
In herbicide plots on tree fruits in the Willamette Valley and at Hood River there has been a consistent correlation between weed control effectiveness and tree growth in young orchards. This appears to be particularly true of weed control during the spring and summer obtained from spring applications as compared...

A method is described to determine the distribution of the bending stresses in a wood beam when some of these stresses exceed the proportional limit. This is used to calculate the position of the neutral axis and the bending strength of some Douglas-fir beams. The calculated values agreed with the...
An anemia of juvenile chinook salmon (Oncorhynchus tshawytscha) is described and stages of development separated by recognizable syndromes. A vitamin E-deficient diet of low rancidity produced a severe microcytic anemia with strong immature red cell response and granulocytosis occurring 2 to 4 weeks before a drop in hemoglobin and hematocrit...
Part I. To aid in the management of the Tillamook Bay commercial salmon fishery, a tagging program was conducted on the salmon and steelhead trout runs in 1953. General migration behavior, the minimum length of time the fish remained in the fishery, population sizes, and fishing mortalities were determined from...
Clatsop Beaches, characterized by flat beach-face slope (1:70) and small sandsize (0.2 mm.), have supported commercial and recreational fisheries for the razor clam (Siliqua patula) for many years. Tracing the linear growth of two year classes through more than one year following set led to a validation of the ring...
The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...
