• (2022) The First Evaluation of the ‘WieSEL’ Integrated Plot Combine Grain Yield System A study of the WeiSEL, manufactured by Zurn Harvesting of Germany, shows that the new plot combine yield measurement system is a less expensive and reliable alternative to manual yield collection methods.
• (2020) Performance of Hard Red Winter Wheat in Late-Planted Fallow This publication describes results of field research on the performance of hard red winter wheat cultivars in a late-planted fallow system in the low-precipitation zone of Oregon and Washington.
• (2012) Phosphorus Fertilization of Late-Planted Winter Wheat in No-Till Fallow This publication describes results of applied research on phosphorus fertilization of late-planted winter wheat in no-till fallow in the low-precipitation zone of Oregon and Washington.
• (2023) Winter Wheat in Summer-Fallow Systems (Intermediate Precipitation Zone) Fertilizer Guide Addresses nutritional requirements of nonirrigated cereal crops in north-central and eastern Oregon. Includes recommendations for nitrogen, phosphorus, potassium, sulfur, chloride, and zinc.
• (2023) Winter Wheat in Continuous Cropping Systems (Intermediate Precipitation Zone) Fertilizer Guide Addresses nutritional requirements of nonirrigated cereal crops in north-central and eastern Oregon. Includes recommendations for nitrogen, phosphorus, potassium, sulfur, chloride, and zinc.
• (2007) Managing Nitrogen for Yield and Protein in Hard Wheat The successful production of hard wheat with acceptable protein is based, in part, on an effective nitrogen (N) management plan. This fact sheet discusses the principles of managing N for hard wheat production and explains how to calculate an N application rate. The information contained in this fact sheet is applicable to both irrigated and dryland production systems in eastern Oregon.
• (2023) Winter Wheat in Continuous Cropping Systems (High Precipitation Zone) Fertilizer Guide Addresses nutritional requirements of nonirrigated cereal crops in north-central and eastern Oregon. Includes recommendations for nitrogen, phosphorus, potassium, sulfur, chloride, and zinc.
• (2023) Winter Wheat and Spring Grains in Continuous Cropping Systems (Low Precipitation Zone) Fertilizer Guide Addresses nutritional requirements of nonirrigated cereal crops in north-central and eastern Oregon. Includes recommendations for nitrogen, phosphorus, potassium, sulfur, chloride, and zinc.
• (2023) Winter Wheat in Summer-Fallow Systems (Low Precipitation Zone) Fertilizer Guide Addresses nutritional requirements of nonirrigated cereal crops in north-central and eastern Oregon. Includes recommendations for nitrogen, phosphorus, potassium, sulfur, chloride, and zinc.
• (2009) Agronomic Guidelines for Flexible Cropping Systems in Dryland Areas of Oregon Plant-available soil water is the most reliable indicator of potential yield and is the basis of guidelines found in this publication.
• (2010) Irrigated Soft White Wheat (Eastern Oregon) Nutrient Management Guide Management recommendations focusing on rate, timing, source, and method of nutrient application for irrigated wheat production in eastern Oregon.
• (2006) Monitoring Soil Nutrients in Dryland Systems Using Management Units Focuses on how to design a soil nutrient monitoring strategy using management units or zones for soil testing and nutrient application. This approach is designed to provide better information to make nutrient management decisions at a reasonable cost. Using a management unit approach, a grower can vary the amount and type of nutrient applications within a field. Two examples of nutrient monitoring are provided to illustrate the process of deciding when, where, and how to sample, as well as how to interpret soil test results.
• (2007) Irrigated and Dryland Canola Nutrient Management Guide Provides nutrient application recommendations for nitrogen, sulfur, phosphorus, potassium, zinc, boron, and pH adjustment. Includes example fertilizer application rate calculations.
