  • 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


Summary of seeding rate and date l.jpg

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

Nitrogen and fungicide impacts l.jpg

Nitrogen and Fungicide impacts

Is there value to applying Headline at various Nitrogen rates?


Nitrogen fungicide l.jpg

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


Harvest system impacts l.jpg

Harvest system impacts

Reglone, glyphosate and swathing

Samples left in field for 0 to 7 weeks in fall

Slope position and cutting height l.jpg

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
