Effect of Soil Acidity and Nitrogen on Yield and Elemental Concentration of Bush Bean, Carrot, and Lettuce

Creator:: Hemphill, Delbert D. Jr and Jackson, T. L. (Thomas Lloyd), 1922-
Abstract:: Bush beans (Phaseolus vulgaris L.), carrots (Daucus carota L.), and lettuce (Lactuca sativa L.) were grown for 3 years on soils amended with S or lime and N fertilizer. Yields of all crops increased with lime application but response to N varied among crops and years. Lettuce head weight tended...

Wheat genotypes selected under optimum conditions and their response to water and heat stress

Creator:: Briceno-Felix, Guillermo Ariel
Abstract:: Concerns have been expressed that wheat (Triticum aestivum L.) cultivars selected under optimum conditions may lack adequate adaptation for stress environments. Experimental populations were grown under three environmental conditions 1) optimum, 2) reduced irrigation, and 3) high temperature. Field experiments were conducted at the Center for Northwest Experimental Station (CIANO),...

Crop Response to Lime in the Western United States

Creator:: Jackson, T. L. (Thomas Lloyd), 1922- and Reisenauer, H. M.
Abstract:: The western states include a complex combination of geological, topographical, climatic, and vegetative features. The region extends through 1900 km of latitude and contains three major north-south, storm-directing mountain systems. Most of the region is arid (annual precipitation < 50 em); however, sizeable agriculturally important areas west of the Cascade...

The effect of preplant nitrogen fertilization and soil temperature on biological nitrogen fixation and yield of alfalfa (Medicago sativa L.)

Creator:: Shuler, Philip E.
Abstract:: The usefulness of preplant nitrogen (N) in establishing alfalfa in colder production areas has not been well characterized. This study was conducted to determine the effect of preplant N and soil temperature on yield, percent N derived from biological nitrogen fixation (PBNF), and shoot N concentration in alfalfa (Medicago sativa...

Predicting Phosphorus Needs in Snap Beans : 2013 Research report to the Oregon Processed Vegetable Commission

Creator:: Heinrich, Aaron, Peachey, Ed, and Sullivan, Dan M.
Abstract:: Although Oregon is the #2 snap bean producer in the US, yield of snap beans per acre is greater in Oregon than any other state (USDA NASS 2012). Despite the scale and importance of snap bean production in Oregon, almost no research has been done on phosphorus (P) utilization over...

Jointed goatgrass : outcrossing, competition with winter wheat, and response to timing and rate of imazamox

Creator:: Cannon, Joshua B.
Abstract:: Jointed goatgrass (Aegilops cylindrica Host.) is a serious weed problem in wheat (Triticum aestivum L.) production in the United States. Studies were conducted to determine the outcrossing rate, competitive ability, and effectiveness of certain control practices on jointed goatgrass. A field study was conducted over two years at four locations...

Effect of nitrogen and water stresses during tillering and grain- filling in wheat

Creator:: Ashraf, Muhammad, 1952-
Abstract:: The CERES-Wheat Crop Growth and Development model treats temperature, nitrogen and water stresses as limiting factors. For each day the model calculates a stress index for temperature, N and water, compares the magnitude of the indices, and then adjusts the calculated daily potential growth using the index of the most...

Response of Roughstalk Bluegrass (Poa trivialis L.) to Waterlogging Stress

Creator:: Liu, Mingyang
Abstract:: Roughstalk bluegrass (Poa trivialis L.) (RB) is a weed species that increased very quickly in grass seed production fields of the Willamette Valley. The invasion of RB in grass seed crops often occurs in waterlogged soils. In waterlogged areas, RB exhibited better competitiveness and had greater population densities than other...
