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...
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...

Nisin, bacteriocin produced by Lactococcus lactis, Nisin may have the potential to replace (or reduce) sulfiting agents traditionally added to wines to prevent the growth of spoilage lactic acid bacteria. This may be valuable since sulfites are believed to cause toxic responses in sensitive individuals. As a result, the U.S....
The new varietal trial at SOES was monitored during the growing season and during ripening by David Sugar and Porter Lombard (see Winegrape Variety Trial in Southern Oregon). The 1993 vintage was a late ripening season and not all the varieties developed sufficient maturity for experimental wine production. Tempranillo, Viognier,...
"In the past 6 years research effort on the Marbled Murrelet (Brachyramphus marmoratus) has increased in response to an apparent dramatic decline in their numbers on the west coast south of British Columbia (Marshall, 1988, Carter and Erickson 1992, Nelson et al. 1992). Their recent listing as a federally threatened...
Summaries from 49 published articles on tree volume and taper equations are presented for 39 tree species found in California, Oregon, Washington, British Columbia, southeast Alaska, Idaho, and western Montana. The summaries are organized by species and then by type of equation (volume or taper). Each summary describes the types...
Minimal pruning continues to look like a production system worthy of consideration in small scale commercial trials. In 1993, in a trial on Chardonnay at Woodhall vineyard, minimal pruning was compared to standard cane pruned vines on a vertical trellis. This was the second year of the trial.
In addition to statistics on bay clams, the report mentions an effort to plant native (Olympia) oysters (Ostrea lurida / Ostrea conchaphila) in Netarts Bay.
This is an exhibit made by the Oregon Department of Fish and Wildlife to the Oregon Fish and Wildlife Commission on October 19, 1994. Topics covered include a summary of the 1993/1994 crab fishery, analysis of the use of long-line gear in crab fisheries, and standards for biodegradable twine on...
The connection between the fruit-set disorder Inflorescence Necrosis (IN) and high ammonium (NI14+) in affected tissues has led to an investigation of NH4+ assimilation enzymes (principally glutamine synthetase (GS) and glutamate synthase) in grape tissues. Previous work in this department has suggested that toxic levels of NH4+ build up in...
The BEST (Benguela Source and Transport) project was designed to investigate the form
of the Benguela Current and ratio of the Aguhlhas Current and South Atlantic Current
source waters masses. The transport of the Benguela Current and its variability was
measured by a moored array of instruments, inverted echo sounders...

The public expects and deserves
a safe food supply. This
includes food free of antibiotic
residues. Congress has empowered
the Food and Drug Administration
(FDA) to examine and
closely monitor the use of animal
drugs in dairy herds across the
nation. This regulatory agency has
the power of enforcement action.

Agricultural scientists recognize farmer knowledge and experience can provide important contributions to the development of new agricultural technologies. However, insufficient use has been made of this valuable resource because farmer knowledge and experience are difficult to collect, quantify, and evaluate.

Four factors govern the potential for groundwater
contamination by pesticides passing through the soil:
• Properties of the soil
• Properties of the pesticide
• Hydraulic loading on the soil
• Crop management practices

The first through fifth instars of the gypsy moth were tested for development to adults on
326 species of dicotyledonous plants in laboratory feeding trials. Among accepted plants,
differences in suitability were documented by measuring female pupal weights. The majority of
accepted plants belong to the subclasses Dilleniidae, Hamamelidae, and...

in a drought, every gallon of water saved
means more crop production. There are many
places in a typical irrigation operation where
water is lost. Here are some prudent management
practices that can conserve water and
possibly make the difference between making
a profit or taking a loss.
Note: These...
