The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El Niño. Since then, numbers...
The following taxonomic keys are adapted in part from the subgeneric and species descriptions and keys produced by McGinley (2003), Gibbs et al. (2013) and Gardner and Gibbs (2022). Additional identification information was provided by Jason Gibbs, Thilina Hettiarachchi (University of Manitoba), and Joel Gardner (Washington State University). While these...
The goals of this work are to a) understand community perspectives related to public engagement with science and the Luquillo Long Term Ecological Research (LUQ-LTER) program, b) enhance existing relationships within these communities, and c) illuminate opportunities for establishing new relationships between the LUQ-LTER program and its surrounding community. We...
For many years brined cherry stocks for eastern maraschino cherry processors were almost entirely imported from Italy and France. Only small quantities were barreled on the Pacific Coast for local use. Today that situation is almost entirely reversed. With the aid of a protective tariff on brined and processed cherries...
The end of the European phase of the war lessens somewhat the demands on the military for food in one theater of operations. The successful prosecution of the Pacific phase of the war and the needs of the liberated peoples of the world, plus the civilian requirements of the allied...

In Southern Oregon, grass seed production occupies a small acreage, but is an important part of agronomic crop production. The high value of sod quality bentgrass seed (Agrostis palustris Huds.) led to some growers supplementing soil fertilizers with foliar fertilizers in an attempt to increase seed yield. However, this practice...
The recent increase in energy prices and political instability in the Middle East has sparked renewed interest in alternative energy sources and technologies both locally and nationally. Biodiesel is an appealing transportation fuel source for many reasons: it readily substitutes for petroleum diesel, it tends to burn cleaner with fewer...

Grain is produced on about 100,000 acres in the Klamath Basin and 60,000 acres within the Klamath Reclamation Project. Susceptibility to late spring frosts has historically limited winter cereal production and spring cereals have accounted for the majority of production. Starting in 2003, a significant shift to production of hard...

As we described previously and elsewhere in this annual report, teff (Eragrostis tef [Zucc.], Poaceae) is a warm season (C4) annual tropical grass that can produce good quality forage during a short summer time frame, and thus has the potential to be a viable crop choice when forage producers: a)...
There are times when forage producers desire a quick-growing, high quality annual forage in mid-summer in situations such as: less-than full season irrigation water supply; need for an emergency crop due to crop failure; or forage rotation crop between alfalfa stands. Currently there are few good options in these situations....

Euphorbia lagascae has been recognized as one of the more promising potential new industrial crops for temperate latitudes (Roseberg, 1996).

The agronomy research program at OSU-KBREC has several objectives. We continue to test traditional crops such as small grains (wheat and barley), forages (alfalfa and grass hay), new forage and niche grain crops (i.e. teff), and crop production practices for these crops (i.e. conventional and organic soil fertility methods), evaluating...

The objectives of this trial were to:
1. Compare onion yield under surge irrigation with continuous flow irrigation.
2. Estimate irrigation efficiency under surge irrigation and continuous flow irrigation.
3. Compare estimates of nitrogen leaching under surge irrigation with continuous flow irrigation.
Straw mulch was evaluated on a furrow-irrigated sugar beet field to determine potential benefits In Increased yield, better soil moisture status, and reduced soil erosion.
Stephens winter wheat was grown using conventional furrow irrigation and surge irrigation on 12 one-half-acre plots. Both systems were operated simultaneously four times during the season. Conventional irrigation applied 26.5 ac-in/ac of water with runoff of 0.8 ac-in/ac and infiltration of 25.7 ac-in/ac. Surge irrigation applied 13.7 ac-in/ac with 0.5...
Treasure spring wheat was grown using conventional furrow irrigation and surge irrigation on 12 one-half-acre plots. Both systems were operated simultaneously five times during the season. Conventional irrigation applied 24.7 ac-in of water with runoff of 5.6 ac-in and infiltration of 19.1 ac-in. Surge irrigation applied 12.0 ac-in with 1.7...
Surge irrigation of furrow-irrigated spring wheat was investigated at the Malheur Experiment Station in 1991. The project studied the feasibility of implementing surge as an irrigation management method for increasing irrigation efficiency and reducing deep percolation of irrigation water from furrow-irrigated fields in Malheur County.
Surge irrigation is a process...
Polyacrylamide and straw mulch were used to reduce soil erosion on furrow irrigated potatoes. The PAM rate started out at 1 lb/ac per irrigation, then in the second irrigation of the wheel rows the rate was reduced to 0.2 lb/ac. The rate was increased to 0.5 lb/ac for all subsequent...
Treasure spring wheat was grown on sloping ground with and without mechanically applied furrow mulching. Furrow mulching used 800 lb/ac of wheat straw. Mulched and non-mulched furrows were irrigated five times during the season receiving 483 and 19.0 and 40.9 ac-in of irrigation water, respectively. For non-mulched furrows, infiltration totaled...
Shepody potatoes were grown under sprinkler irrigation on sloping ground (4.2 to 8.5 percent slope) with and without mechanically applied wheat straw, grass straw, or reservoir tillage. Mechanical furrow mulching used 1,000 lbs/ac of wheat straw or grass straw. Mulched, non-mulched, reservoir-tillage, and check plots were irrigated 12 times with...
The potential of mechanically applied straw mulch to reduce nutrient, pesticide and sediment losses from furrow irrigated onions and increase water use efficiency was evaluated on a Nyssa silt loam with three percent slope. Nitrogen and phosphorus losses in the runoff were of particular interest, both because of their economic...
Russet Burbank, Shepody, Frontier Russet, and Ranger Russet potatoes were tested for their response under furrow irrigation to PAM-treated irrigation water. The use of PAM was associated with an increase in US Number One tubers for Russet Burbank and Shepody varieties.
A Nyssa slit loam soil was bedded for potatoes. Furrow irrigation for 11 hours at four gallons per minute on a 2.5 percent slope resulted in 17.7 tons of soil lost per acre. Soil loss was reduced to 2.8 tons per acre by the use of 790 lbs/acre of wheat...
Surface crusting of soil after planting can result in poor emergence and reduced stands. The use of polysaccharides and polyelectrolytes for soil conditioning has been found to improve seedling emergence. This trial evaluated the use of a molasses and nutrient based soil conditioner (Bright Sun Soil Booster, Cargill Inc., Minneapolis,...
