    Proposal abstract:

    Organic producers across the West
    consistently report that high costs and limited availability of
    regionally adapted organic cover crop seed are major barriers to
    expanding cover cropping. Most seed is produced far from end users,
    often as "variety not stated," leaving farmers uncertain about
    performance, yield potential, and whether dedicating acreage to
    seed production can pencil out. At the same time, many farmers are
    interested in producing their own cover crop seed but lack
    practical information on agronomy, seed cleaning, and enterprise
    economics.

    This project will test whether
    on-farm cover crop seed production can be a viable and scalable
    strategy to lower costs, strengthen local seed systems, and support
    wider cover crop adoption. Four certified-organic farms in coastal,
    interior, and mountain/continental eco-zones (College of the
    Redwoods Farm, Eel River Produce, Neukom Farm, and Swift River
    Farm) will conduct two years of producer-led trials. Using
    NCCVT-aligned methods, they will compare single-species versus
    mixed-species seed production, evaluate yield and seed quality of
    key legume and cereal cover crops, and link yield, germination, and
    cleaning efficiency to weather and eco-zone.

    Education activities will
    translate these findings into practical tools: producer-led field
    days; three concise Seed Crop Quick Profiles; two enterprise case
    studies; a "do-it-this-season" seed-enterprise toolkit (budget
    workbook and cleaning log); and two webinars plus short videos.
    Together, these outputs will give Western farmers concrete
    agronomic and economic guidance to decide if and how to add on-farm
    cover crop seed production to their operations.

    Project objectives from proposal:

    Research Objectives

    1. Compare the economics of
      single-species vs. mixed-species on-farm cover crop seed
      production.

    2. Evaluate yield and seed quality
      of priority cover crop species and varieties across sites.

    3. Quantify how weather and
      eco-zone differences affect cover crop seed yield and quality.

    Education Objectives

    1. Provide producer-led field days
      demonstrating cover crop seed production and cleaning.

    2. Develop and share practical seed
      crop profiles and enterprise case studies.

    3. Create and disseminate a simple
      seed-enterprise toolkit for on-farm cover crop seed production.

    4. Deliver webinars and short
      videos to extend project findings to a wider audience.
