Maximizing canola yields with harvest options

There is no one best way to harvest canola. Each harvest method has its advantages and disadvantages and only with proper field assessment can you determine which method, or combination or methods, will result in your highest yields per acre.
To help you maximize your canola yields and minimize your stress levels, here are some harvest management best practices to consider when deciding whether to swath, delay swathing 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%).
