  1. Canola Production, Management, and Harvest Topics Chad Godsey Plant & Soil Sciences Extension Annual Winter Ag Conference Feb. 9, 2012

  2. Canola Management

  3. Management practices to maintain high yield potential • Weed Control • Top-dressing • Insect mgt. • Harvest

  4. Grasses Assure II (quizalofop) Select (clethodim) Poast (sethoxydim) Broadleaves Stinger (clopyralid) Grasses and Broadleaves Roundup (glyphosate) Weed Control

  5. Spray Weeds Early! Early Spray Late Spray

  6. Canola Yield by Herbicide Application Date Almost 45 bu/A at 4 weeks after Planting You lose about 1.33 bu/week

  7. Top-dressing • Rule of thumb is 5 lb N/ac for every 100 lb of yield • 2000 lb/yield goal would result in 100 lb N/ac • Consider pre-plant and residual N, current stand • Other top-dress nutrients (S and B)

  8. 2010-11 Yield (Lahoma)

  9. Insects • You never know what we are going to see • SCOUT, SCOUT, SCOUT on a weekly basis! • Management of Insect and Mite Pests in Canola CR-7667

  10. Canola Harvesting Options • Direct Cut • Most risky • Good yield IF no shatter • Shortest harvest window • Swathing • Evens out maturity • Dries down fast • Pushing • Longer seed fill than swath

  11. Pushing Recommendations • Between 40-60% seed color change • Push as high as possible • 1:10 kinked, stalks should just curve at least 45 degrees • Better on tall and thick canola

  12. Swathing Recommendations • Between 40-60% seed color change • Or at 30-40% seed moisture content

  13. Seed Color Change • Sample across the field • Sample daily as time gets close • Inspect the top, middle, and bottom of the seed pod canopy on the main stem • Top will typically turn faster than the rest when it’s dry and hot out • Take average to make decision

  14. May 18th – First Pushing DKW 41-10 HyClass 154

  15. May 21 – 2nd Push, 1st Swath DKW 41-10 HyClass 154

  16. May 24 – 3rd Push, 2nd Swath DKW 41-10 HyClass 154

  17. May 24th – Swath Dry Down

  18. May 26 – 4th Push, 3rd Swath DKW 41-10 HyClass 154

  19. May 28 – 5th Push, 4th Swath DKW 41-10 HyClass 154

  20. June 1 – 6th Push, 5th Swath DKW 41-10 HyClass 154

  21. % Seed Color Change

  22. Dekalb 41-10 Yield by Date

  23. HyClass 154 Yield by Date

  24. Canola Test Weight

  25. Summary • Best methods depends on if you are a risk taker. • In a perfect world with no bad weather direct harvest equals highest yield, but is more risky. • Pushing provides a longer window than swathing. • Do not swath too early.

  26. Summary • Top-dress and weed control decisions need to be made soon. • Stay on top of insect populations. • Make a plan and have a back-up plan for harvest.
