Best management practices for maximizing canola yields with harvest options

Something went wrong. Please try again later...

Proper harvest management is key to maximizing your canola yields, but when balancing heavy workloads with weather and field conditions, it isn’t always easy or straightforward.

While you know your fields better than anyone and are likely to have your preferences, there is no one best way to harvest canola. Each harvest method - swathing, delayed swathing and straight cutting - has its advantages and disadvantages and only with proper field assessment (just prior to 60% seed colour change) can you determine which method, or combination or methods, will result in your highest yields per acre.

To help you achieve the highest yields possible with the least amount of stress, here are some things to consider when deciding whether to swath, delay swath or straight cut:

Swathing may be an option if:

  • Crop canopy is upright and not well knit together
  • Uneven crop staging from uneven crop emergence, disease, weedy patches or early season frost
  • Risk of early fall frost
  • Thin, short or lodged plant stand
  • The optimum stage to swath for both yield and quality is 60% seed colour change

Delayed swath may be an option if:

  • You grew a canola hybrid with reduced risk of shatter 
  • You need more time to help spread out the workload (waiting until 80% seed colour change could help, for instance)
  • Adverse weather conditions are in the forecast at 60% seed colour change when one would normally swath
  • The crop is well knitted with minimal disease or insect damage
  • Risk of early fall frost is low

Straight cutting may be an option if:

  • You seeded a canola hybrid with reduced risk of shatter
  • Plants are well knitted with a slight lean to protect against severe wind events
  • Crop maturation is even and uniform
  • Limited disease, hail or insect damage to plants or pods
  • There is a need to balance weather, crop conditions and maturity with your farm’s time efficiency (manpower and machinery)
  • Seed moisture is <10% with minimal green seed (ideally < 2%).

Options to overcome today’s harvest challenges

One of the biggest factors in determining your crop’s suitability for swathing, delayed swathing or straight cutting is your canola hybrid. Through Corteva Agriscience’s two premium seed brands, Pioneer and Brevant® seeds, growers can choose from a portfolio of hybrids with harvesting options that meet the needs of their operation.

The genetic package in Corteva canola hybrids also includes built-in traits such as clubroot (various new sources of resistance), sclerotinia and blackleg resistance, so you get a season-long solution that maximizes yield potential and disease protection.
