Creator:: Peachey, Ed and Heinrich, Aaron
Abstract:: The overall objective of this three-year project was to provide farmers with updated fertilizer recommendations for snap beans. The goal was to maximize nutrient use efficiency without compromising bean yield and quality. This was accomplished by partnering with commercial bean growers to conduct on-farm research as well as conducting trials...

Abstract:: The enhanced efficiency (EEF) products we tested in our study hold the potential to increase the nitrogen utilization efficiency of sweet corn as well as reduce nitrate leaching when all N fertilizer is applied before planting. However, this potential is limited by weather (i.e. large early season rainfall events), irrigation...

Abstract:: Three forecasting programs for scheduling fungicide applications were selected for comparison with the standard Oregon phenology based program. The UCDavis (California) program used leaf wetness and temperature early in the year and only temperature during the summer. The New York program was based on rainfall and temperature. The German Oi...

Abstract:: Spring freeze decreased the yield of field grown grapevines by 70%. The spring bud development of Pinot noir was characterized into seven stages after the initial budbreak, 96% of the buds attained full development in 44 days. Controlled freezing tests were used to determine bud hardiness. The T50 values (temperature...

Creator:: Horneck, Donald A.
Abstract:: Soil testing for a perennial crop, especially a crop new to Oregon such as grapes, raises three common questions from growers: is a soil test desired, how many samples are needed and what do the results indicate? Soil samples are needed before planting a vineyard. These samples provide a record...

Abstract:: The overall objective of this multi-year project is to maximize nutrient use efficiency without compromising bean yield and quality. This year’s project objectives were to: 1) evaluate crop response to P fertilizer at current soil P test levels in grower fields; 2) generate phosphorus (P) potassium (K), and nitrogen (N)...

Abstract:: Objectives of proposed research: 1. Investigate the relationship between abscisic acid (ABA) and auxins and the regulation of carbon partitioning. 2. Investigate the origin of ABA present in the fruit during ripening and attempt to modify the partitioning pattern through manipulation of endogenous ABA levels using mefluidide (ABA biosynthesis promoter)...

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...

Abstract:: Fertilizer recommendations in this guide are based on the use of well-adapted varieties and disease free plants, selection of suitable soils, disease and insect control, weed control, and proper irrigation. Application of these management practices is essential to realize optimum fertilizer response. Strawberries respond to generous amounts of soil organic...
