Annual Reports


  • Agronomic: sunflower

  • Farm Business Management: whole farm planning, feasibility study
  • Sustainable Communities: sustainability measures

    Proposal summary:

    Starting in October 2005, synthetic methionine will no longer be allowed in organic poultry feeds. Methionine is the limiting amino acid for poultry; without it, egg and meat production is severely compromised. This project will test whether sunflowers are the most reasonable solution to the organic methionine problem by conducting a sunflower variety trial, identifying efficient ways to de-hull sunflowers, and conducting a feeding trial to determine the merit of using sunflowers as an organic source of methionine. Outreach will be via pamphlets, presentations, farm tours, and articles.
