Tips for Growing High Yielding Canola

• Achieving a 60 bu/acre canola crop is an ambitious but attainable goal for Canadian growers committed to best management practices.
• Success depends on making informed decisions at every stage—from hybrid selection and fertility planning to pest management and harvest timing.
• By combining strong genetics with precise agronomy and careful record keeping, you can maximize canola yield potential and profitability.
• The following guidelines outline key steps and considerations to help you achieve top-end canola yields and profitability on your farm.

• Target 5-8 plants per square foot for optimal yield potential. This range balances economics and reduces risks from pests, weeds, and uneven maturity. Lower populations (<5 plants/ft²) make crops vulnerable to stress and delay maturity.
• Uniform emergence is critical. Ensure proper seeding depth (½-1 inch), consistent seed placement, and aim for ~4 mph seeding speed to ensure adequate furrow closure and seed/soil contact.
• Avoid canola-on-canola stubble; yields may drop significantly (~10-20% yield difference¹) when seeded into canola stubble versus cereal stubble.

• Select hybrids with strong disease resistance (blackleg, clubroot, sclerotinia, verticillium), appropriate maturity for your region, and enhanced pod shatter performance where straight cut harvesting is a possibility.
• Pioneer’s Pod Shatter Premium Technology brings confidence to straight-cut harvesting, enables harvest management decision flexibility and superior yield potential.

 

• Pioneer’s internal trials showcase high yielding hybrid options for broad Western Canada adaptation, complemented by early/mid/late maturity options and disease protection against blackleg, clubroot, sclerotinia, and verticillium stripe.
• Pioneer hybrids support a multi-hybrid strategy to mitigate risk and optimize yield and profitability across Western Canada.²

• Canola is a high-value crop with significant nutrient demands, particularly nitrogen, phosphorus, potassium, and sulfur.
• Applying the 4R principles—Right Source, Right Rate, Right Time, and Right Place—ensures nutrients are used efficiently, supporting optimal yield and oil quality while minimizing environmental impact.
• Proper nutrient management reduces losses to air and water, improves soil health, and maximizes return on investment.
• Table 1 shows the recommended canola fertilizer guidelines.
• Micronutrients are equally important to the success of a high producing crop and should be factored into fertility recommendations.
• Adjustments based on soil test results and other factors such as nutrient placement/timing/source/method, should always be factored into a successful fertility program.
• Consult with your local agronomist or fertilizer supplier on a soil testing plan and nutrient recommendations for your farm.

• Western Canadian canola crops may experience flea beetle, sclerotinia, blackleg, and verticillium stripe infections on a yearly basis.
• Clubroot, as well as insects such as cutworms, diamondback moth, and others may also cause yield reductions if present.
• Use disease resistant hybrids and seed treatments as part of an effective management plan. Consider a 1 in 3- or 4-year canola crop rotation to increase yield and profitability expectations for all phases of the crop rotation.⁵
• Manage volunteer canola aggressively; it hosts diseases and competes for nutrients.
• Harvest losses can add ~1.3 bu/acre of seed to the seedbank, persisting for years.⁶ Ensure effective harvest management practices are followed (e.g., combine settings, harvest timing, etc.). In a comprehensive crop rotation it is recommended to alternate between herbicide systems.

• Swathing at 60-70% (or later) seed colour change optimizes yield and quality if crop staging is uneven or frost risk is high. It is a preferred harvest management method to even out harvest risk during a challenging fall.
• Pioneer field-scale trials show that canola swaths can be harvest ready as much as 6-7 days sooner than straight cut in the same field.
• Straight-cutting canola at ~10% seed moisture often delivers efficiency in manpower and equipment costs but comes with risk associated with challenging environmental conditions that could result in pod shatter and/or drop, thereby reducing overall yield and profitability.
• Factor in the cost of desiccation when comparing straight-cut vs swathing on your farm. Avoid harvest delays beyond 90% SCC or 10% seed moisture content to minimize shatter losses.

• Include both Optimum® GLY and LibertyLink® traited canola on your farm as an effective way to manage herbicide resistant weeds as well as volunteer canola.
• Maximize soil moisture retention through residue management and reduced tillage.
• Manage weeds early to reduce yield robbing competition.
• Consider a multi-hybrid approach for disease-prone or early-maturity zones.
