Northwest and Allee Research and Demonstration Farm
Recently, demand for organic flax (Linum usitatissimum) in the upper Midwest has increased due to consumer demand for flaxseed to improve diets and due to the recent construction of a certified organic oilseed expelling facility in Cherokee, IA. Challenges exist to raising flax in Iowa, yet the majority of production guidelines are from the 1940s, or from the cooler and drier climates of North Dakota and Canada. Flax production in these areas is typically managed using chemical pesticides and synthetic fertilizers. Growers in the upper Midwest need region-specific guidelines and information for organic production. During the 2005 and 2006 growing seasons, cultivar and planting date effects on grain yield, oil quantity, and oil quality were studied.
