Field Lessons Learned

Field Lessons Learned

  • Yields & test weights were good and quality was No. 1. Green seed was not a problem. Winter tolerance was excellent.
  • We need for more variety performance data.
  • Wide spread use of Finesse and Maverick on wheat is currently a limiting factor in rotation to canola.
  • Crop must be combined when it is ready.
  • Seed bed preparation is important! Good seed to soil contact with moisture is required. Consider stale seed beds at planting.
  • Canola can be harvested when wheat is to damp or tough to thrash.
  • Major canola diseases were not a problem.
  • Late freeze at flowering showed minor effect on overall yields.
  • Volunteer canola in wheat the following year will be easy to control.
  • Carefully evaluate a thin stand in the spring before destroying it.
  • Winter wheat is a major weed species in winter canola.
  • Grazing can seriously hurt canola yields.
  • You will have volunteer canola in fields after harvest.
  • Cutworms can become a serious fall and winter problem.
  • Excellent weed control with Roundup Ultra Max II in RR canola fields. Still have questions on RR and conventional herbicides with rates and timings.
  • Canola is an excellent forage compared to wheat. Canola has approximately twice the RFV.
  • Aphid (Cabbage aphid) management during flowering and after flowering are important.
  • Custom combine crews know how to harvest canola
  • More information is needed when planting canola in no-till situations. But what we have seen looks good. Planting speed seems to be an issue.
  • Drills need to be calibrated before planting canola.
  • Best to plant after a rain than before a rain.
  • Be careful banding fertilizer with the canola seed.
  • Clean sprayer thoroughly before spraying canola.
