Flax (Linum usitatissimum L.) is a multi-purpose crop grown for its fiber, oil (linseed oil), and meal. The majority of production occurs in the Dakotas, Minnesota, and Montana. Recently there has been interest in growing flax in the northeast, both for human consumption and for animal feed, for its high levels of heart-healthy omega-3 fatty acids. Flax is a spring annual that is usually planted as early as the ground can be worked. However, one of the main challenges to successfully growing flax is weed control. Flax plants compete poorly with fast growing weeds due to its relatively short height (between 12 and 36 inches when mature) and tiny leaves. This trial was initiated to see if management, including different row spacing and cultivation, would reduce weed density in flax and improve yields.
