Buckwheat (Fagopyrum esculentum Moench) is a broadleaf crop that is in the same plant family as rhubarb. It is not related to any other wheat, and consequently is an excellent rotation crop in small grain cropping systems. Buckwheat is adapted to a wide variety of soils and climates and is produced extensively in North Dakota, Minnesota, South Dakota, and Washington.

Minn-Dak contracts directly with farmers and provide them with the latest crop production research to produce top quality buckwheat for processing. Our farm level research program includes:

  • Studying the mechanisms of seed set and yield in buckwheat.
    This research has resulted in:
    a. Reducing buckwheat yield variability.
    b. Providing information to assist plant breeders in developing higher yielding varieties.
    c. Developing proprietary computer models to assist farmers in optimizing harvest
  • Minn-Dak’s mission is to develop new buckwheat varieties for its stakeholders.
  • Annual educational seminars for our contract buckwheat producers.

Minn-Dak has an extensive library of buckwheat production information to assist our contract growers in raising the best buckwheat possible. Minn-Dak buckwheat varieties are NOT genetically modified organisms (GMO’S).
