Extension Program: 

Treasure Valley Pest Alert Network Jensen, Lynn, Crop & Soil Science, OSU Extension Malheur County Reddy, Steve, University of Idaho Neufield, Jerry, University of Idaho Shock, Clinton C., Crop & Soil Science, Malheur Experiment Station Environmental: 2 Economic: 3 Social: 1 [Profiles are on a scale of -3 to +3. A blank means that category is not applicable in this case.] This interactive internet-based site delivers timely crop pest information to the Treasure Valley. It receives information from growers and other subscribers; submissions are checked by University of Idaho or OSU Extension agents who post the pest alert on the web page where there are automatic links to appropriate pest identification and control information. The network is rapidly expanding to include a much larger region. back to top

Research Project: 

“Sop Up" Crops to Follow Shallow-Rooted Crops: Efficient Use of Residual and Mineralized N Shock, Clinton C., Crop & Soil Science, Malheur Experiment Station Environmental: 3 Economic: 3 Social: 1 [Profiles are on a scale of -3 to +3. A blank means that category is not applicable in this case.] The two main cash crops of the Treasure Valley are onions and potatoes, but continuous cropping of these shallow-rooted crops leads to a rapid build up of disease, pest, and weed pressure, rendering them less profitable. Although sugar beets and small grains and other crops may seem less profitable, rotation with these "sop up" or "sponge” crops is highly recommended in that they effectively use up residual soil nitrogen. back to top

Research Project: 

Crop Variety Testing for Adaptation to Treasure Valley Conditions Shock, Clinton C., Crop & Soil Science, Malheur Experiment Station Saunders, Monty, Faculty Research Assistant, Malheur Experiment Station Feibert, Erik, Faculty Research Assistant, Malheur Experiment Station Environmental: 1 Economic: 3 Social: [Profiles are on a scale of -3 to +3. A blank means that category is not applicable in this case.] Variety evaluations are ongoing for alfalfa, small grains, potatoes, sugar beets, and onions. Trials look carefully at quality parameters and disease resistance for all of these crops, as well as onion storability after harvest. The aim is to find those varieties most suited to Treasure Valley conditions. back to top

Research Project: 

Polyacryamide (PAM) and Straw Mulch to Reduce Erosion Losses Shock, Clinton C., Crop & Soil Science, Malheur Experiment Station Environmental: 3 Economic: 3 Social: 1 [Profiles are on a scale of -3 to +3. A blank means that category is not applicable in this case.] Malheur County suffered substantial sediment and nutrient erosion losses from crop production that ended up in surface- and groundwater. This project tested applying straw mulch in the furrows and polyacryamide (PAM) in irrigation water under various slopes and conditions. Both proved beneficial in substantially reducing erosion while improving crop yields due to better infiltration. Results have been well adopted by growers. back to top

Research Project: 

The Malheur Experiment Station Website (http://www.cropinfo.net/) Shock, Clinton C., Crop & Soil Science, Malheur Experiment Station Feibert, Erik, Faculty Research Assistant, Malheur Experiment Station Environmental: 2 Economic: 3 Social: 1 [Profiles are on a scale of -3 to +3. A blank means that category is not applicable in this case.] The station web site posts relevant information that addresses grower needs. The web site is linked to many sources of research at OSU and beyond. It has special sections on Best Management Practices and micro-irrigation. Station weather data are posted daily. It is linked to many useful sites that provide, for example, daily crop consumptive water use. back to top

Research Project: 

Alternative Crops for the Treasure Valley Shock, Clinton C., Crop & Soil Science, Malheur Experiment Station Feibert, Erik, Faculty Research Assistant, Malheur Experiment Station Norberg, Steve, OSU Extension Service Malheur County Environmental: 2 Economic: 2 Social: 1 [Profiles are on a scale of -3 to +3. A blank means that category is not applicable in this case.] Treasure Valley agriculture uses crop rotation to alleviate compaction and soil problems from high-value crop production of onions, potatoes, and sugar beets. Crops being tested include soybean cultivars for fuel, animal feed, or as a vegetable crop; native plants seeds for reseeding disturbed areas; poplar trees for peeler or saw logs; Hicksii yews for production of the anticancer drug, Taxol, and Teff for summer hay. back to top

research project: 

Increasing Irrigation Efficiency and Improving Fertilizer Management in the Treasure Valley Shock, Clinton C., Crop & Soil Science, Malheur Experiment Station Feibert, Erik, Faculty Research Assistant, Malheur Experiment Station Environmental: 3 Economic: 3 Social: 2 [Profiles are on a scale of -3 to +3. A blank means that category is not applicable in this case.] Beginning by solving the potato “dark-end” problem and continuing by addressing the nitrate groundwater issue and irrigation-induced erosion, this long-term project works to improve irrigation efficiency and fertilizer management with the aim of maximizing yields, while minimizing any adverse environmental consequences related to irrigation and fertilization of Treasure Valley crops. back to top

Research Project: 

Potato Breeding and Variety Development in Oregon Vales, M. Isabel, Crop & Soil Science, Campus James, Steve, Crop & Soil Science, Central Oregon Ag Research Cntr Hane, Dan, Crop & Soil Science, Hermiston Ag Research & Ext Cntr Charlton, Brian A., Crop & Soil Science, Klamath Basin Research & Extension Center Shock, Clinton C., Crop & Soil Science, Malheur Experiment Station Environmental: 2 Economic: 3 Social: 2 [Profiles are on a scale of -3 to +3. A blank means that category is not applicable in this case.] The Oregon varietal development team, with active programs at four OSU branch experiment stations and in Corvallis, develops improved potato varieties, including long russet types with high levels of starch, low reducing sugars, and good fry color for the frozen processing industry; round-white chipping types; and fresh market varieties. Developing varieties with pest and disease resistance is an important aspect. back to top
