• (2023) Resilient dryland farming appropriation (RDFA) 2021 – 2022 annual report: Alternative crop trial Integrating alternative crops into wheat-fallow systems may enhance overall sustainability and soil health. Under the Resilient Dryland Farming Alliance (RDFA), a grower-led initiative, an array of potential alternative crops are being evaluated for diversified and intensified wheat-based systems. This annual report presents the alternative crop yields from the third year of the alternative crop trials. Further details about the overall rationale, objectives, long-term vision, and funding for the RDFA can be found under the "Field Crops" topic here on the OSU Extension website.
• (2022) Resilient dryland farming appropriation (RDFA) 2021 – 2022 annual report: Cover crop trial This report presents the data from the third year of a three-year study. In this relatively wet season, fall-planted cover crops, particularly winter peas and the fall mix, produced substantial biomass and provided season-long ground cover. Spring-planted cover crops had insufficient time to grow before termination was necessary and did not produce substantial biomass. More details about the RDFA project can be found at the project's main page (link provided on .pdf).
• (2021) Integrated Management of Wild Oat in the Pacific Northwest In the Pacific Northwest (PNW), wild oat has become a notable weed pest of small grain and rotational crops, including pulse crops, potato, sugar beet, and oilseed crops. It has infested more than 3 million acres of cropland in Idaho, costing small grain growers in the state alone more than 9 million dollars annually in control costs. Feeding its spread is the fact that it has developed resistance to several herbicides. This PNW provides all the basics you need to mount a defense against the stubborn grass, including its identification, crop impacts, and management strategies. A handy table also lists the brand-name herbicides to which the wild oat has developed resistance, upping the odds on your control efforts.
• (2021) Designing cover and alternative crops for dryland cropping systems in eastern Oregon The Introduction to Resilient Dryland Farming Alliance Project aims to assist growers in designing wheat-alternate cropping systems that will improve soil health without decreasing wheat yields.
• (2020) Best Management Practices for Managing Herbicide Resistance Learn to manage herbicide-resistant weeds on your farm using the most effective methods, also known as best management practices (BMPs).
• (2019) Harvest Weed Seed Control: Applications for PNW Wheat Production Systems This publication discusses the various HWSC systems and their potential suitability for PNW wheat production systems across rainfall regions.
• (2015) IPM Downy Brome Presentation by Judit Barroso, OSU Weed Scientist, on Integrated Weed Management for Downy Brome in Winter Wheat
• (2020) Integrated Management of Feral Rye in Winter Wheat Feral rye (Secale cereale L.), also known as volunteer rye, is a troublesome weed in winter wheat production in the low- and intermediate-rainfall zones of eastern Washington and Oregon and southern Idaho. This publication describes the plant and provides recommendations for its management in winter wheat. Color photographs are included to facilitate identification.
• (2019) Russian Thistle: Management in a Wheat-Fallow Crop Rotation Reviews Russian thistle biology as it relates to management, including seed dormancy and longevity in soil, seed distribution, seed germination and emergence, plant growth after establishment, crop competition, and resistance to herbicides. Outlines key considerations for managing for 3 crop years and 1 fallow year. Describes results from a residue management experiment designed to determine how to reduce tillage while maintaining winter wheat production.
