Variety descriptions and recent yield performance can be obtained in NDSU Extension Circular A-574, North Dakota Small Grain and Flax Variety Performance Description, available at your county extension office. Consider planting certified seed. Certified seed is tested to ensure minimal weed content, high genetic purity and good seed viability. Certified seed consistently outyields bin run seed. Treating flax seed with a recommended fungicide is necessary.
Seed treatment reduces seed decay and seedling blights and can significantly increase stand.
A thicker and more uniform stand produces higher yields. Yellow-seeded varieties are more susceptible to seed decay than brown varieties. Treated seed stored for long periods needs to be retested for germination before use. Flax is a crop that can be grown under fertility levels similar to small grains. Use soil testing as a guide for applying fertilizer whenever possible.
