  1. Flax Fibre Production Systems B. Irvine, D. McAndrew, S. Shirtliff, C. Vera, Biolin

  2. Results why man I’ve gotten lots of results; I know of at least a thousand things that won’t work. Thomas Edison

  3. There needs to be a supply of high quality fibre to ensure profit for processor and farmer • Impact of seeding rate and cultivar • How does nitrogen and fungicide application affect seed and fiber • What is the best way to treat flax before harvest to ensure high seed and fiber yield with rapid retting • What is the impact of field location and cutting height of fibre content and yield

  4. Summary of seeding rate and date • Cultivars did not interact with seeding rate or date • Plant population increased nearly linearly with seeding rate • Early seeding > seed yield linear decrease over seeding rates due in part to lodging and possibly narrow rows • Fiber yield increased with seeding rate

  5. Sweep planted

  6. Hoe planted

  7. Impact of seeding date on fibre yield kg ha-1

  8. Impact of seeding rate on fibre content %

  9. Impact of seeding rate on fiber yield kg ha-1

  10. Impact of seeding rate on stem diameter mm

  11. Nitrogen and Fungicide impacts Is there value to applying Headline at various Nitrogen rates?

  12. Nitrogen *fungicide • Fungicide application increased yields if disease pressure was higher • At some sites this impact increased with nitrogen application rate • Seed and fiber yields increased with N over the entire range • Stem size greater with more nitrogen to be expected • Decision as always is based on risk management and in most season in the major flax growing areas a question mark

  13. Harvest system impacts Reglone, glyphosate and swathing Samples left in field for 0 to 7 weeks in fall

  14. Fried test across sites

  15. Slope position and cutting height In many areas there is a fair bit of topography What is the variation with the field in fiber yield and can we predict this

  16. Anova for landscape position

  17. Correlations of fiber yield with other factors

  18. Impact of Cutting height on yield

  19. Impact slope position
