Wet conditions in parts of Western Canada have prompted some growers to consider broadcasting their canola this year. Broadcasting canola is regarded as a high-risk measure and should only be chosen as a last resort. However, there are some situations where a canola grower has exhausted all their options and when this happens, the decision to broadcast becomes unavoidable. The recent Canola Watch article ‘Broadcast Seeding – May 17, 2017 Issue 8’ published by the Canola Council tackles this very circumstance and offers several tips for success.

  1. Increase the seeding rate – Seed germination and survival could be lower, so to be safe, consider an increase of 1 lb/acre
  2. Adjust fertility – Adjust your P rate, account for higher N losses, and consider broadcasting N and S, then using a drill for the seed to reduce your weight load on the field
  3. Assess residue risk – Successful broadcasting requires good seed to soil contact. This may not be possible in fields with lots of straw cover.
  4. Cultivate or harrow after seeding – Shallow cultivating or harrowing can improve seed to soil contact, and greatly improve results.
  5. Careful with weed control timing – Seeds on the soil can be highly vulnerable to herbicide. Do not apply post-seed glyphosate to LL or CL seeds that remain on the soil surface. RR varieties can tolerate glyphosate at any time, even on the seed.
  6. Reset expectations – Yields for broadcasted fields are typically lower, and growers should be prepared for increased management through the season.
  7. Consider the wind effect – This is more of an issue for spinner spreaders than boom-based spreaders, where the boom is fairly close to the ground. Application on a calm day will help.
