MAXIMIZING YOUR CANOLA ACRE

Through numerous yield improvements and the ongoing release of new trait technologies, Bayer remains committed to helping Canadian growers successfully meet the increasing global demand for canola, but it requires more than outstanding genetics, agronomy is also important.

To help maximize the full yield potential, agronomic performance and consistency of your InVigor® canola hybrids, start implementing a targeted plant population plan on your operation.

Target Plant Populations

Over the past 5 years, the Bayer Product Excellence team has conducted thousands of field trials dedicated to maximizing the performance of InVigor hybrids through best agronomic practices.

To mimic real on-farm conditions, the Product Excellence team uses replicated large-scale trials throughout Western Canada that are 15 times larger than traditional breeding programs designed to test best agronomic practices for InVigor.

Through their extensive research this team recommends a targeted plant population of 5 to 7 plants/ft2 to optimize the performance of your InVigor hybrids.

  • Can improve yield performance
  • Maximizes seedbed utilization and available resources (light, moisture, nutrients)
  • Reduces intra-crop competition for available resources and space
  • Fosters uniform maturity and improved lodging resistance
  • Decreases susceptibility to stressors such as heat and low moisture and reduces potential for disease
  • Improves crop competition which helps weed control

Watch this video to learn how targeting 5 to 7 plants/ft2 can improve your yield performance and what happens when plant populations fall outside this range.

Plant Survivability & Optimal Seeding Rates

Achieving your optimal plant population (5 to 7 plants/ft2) requires careful consideration of both your seeding rate and plant survivability.

With an average survivability of 60% for InVigor hybrids, the Bayer Product Excellence team recommends to start by planting 10 seeds per square foot to target your ideal plant population. Of course every field and season are different, so ongoing monitoring to understand the unique survivability of your fields is essential to your crop’s success.

DETERMINING YOUR SURVIVABILITY THROUGH PLANT COUNTS:

In order to figure out the survivability of your plants, you must first know your plants per square foot. Here is how you do that:

STEP ONE: ESTABLISHMENT COUNT

This count is performed at emergence following your first application of Liberty® herbicide (to remove potential volunteers). Simply count the number of plants in a linear foot of a row.

Calculating Plant Density Formula

 

STEP TWO: FALL STUBBLE COUNT

Ultimately your overall survivability (number of plants that contributed to your yield) is determined from your fall stubble count after harvest. Simply count the number of canola stalks within a linear foot of a row.

Once complete you can use the following equation to determine your unique plant survivability.

Plant Survivability Calculation Formula - Plant survivability calculated by plants per square foot, number of seeds planted, and thousand seed weight

Example

6 Plants/ft2 (stubble count)
10 Seeds/ft2 (seeding rate)
= 60% Survivability

Factors that affect survivability

Crop stress, pest pressures and other unforeseen circumstances can drastically affect your survivability. Should plant populations fall below or exceed your ideal (5 to 7) range, simply re-calibrate your seeding equipment accordingly.

Seed Size & Packaging
Packaging

For the 2019 seeding season, all packaging of InVigor hybrids will fall into four ranges (A, B, C or D) which represents a narrow TSW range to minimize variability. Each bag is designed to seed 10 acres, making it easier to plan for your farm. In addition to the customized TSW information, the new packaging features a seeding rate recommendation designed to target your ideal plant population and optimize your yield potential.

Recommended seeding rate for InVigor canola seed bags

 

Based on extensive research conducted by the Product Excellence team, recommended rates on the bag are based on seeding 10 seed/ft2 to achieve 6 plants/ft2 and assuming 60% survivability. Results may vary on your farm due to environmental factors and preferred management practices.

  • With a wide variation in seed size, you may need to fine-tune seeding rates according to your selected hybrids
  • Every time you change seed lots, with a different TSW belonging to a different Range (A, B, C or D) you must calibrate your seeding equipment accordingly
  • Although most equipment manufacturers have detailed calibration instructions on their websites, we recommend that you consult with yours in order to ensure accuracy

Through new packaging information and handy reference materials, InVigor makes it easy to find your ideal seeding rates.

Seeding Rate Chart

InVigor recommends the following seeding rates (lbs./ac.) based on your desired plant stand (plants/ft2) and thousand seed weight (TSW). If you would like to fine tune your seeding rate to specific TSW, simply identify your TSW and desired plant stand to find your recommended seeding rate.

Fine-Tuning Performance

No two fields are the same. Due to specific environmental factors, field conditions and/or farming practices, fine-tuning your seeding rates based on your specific circumstances can lead to even better results. Diligent record keeping, monitoring the survivability in your fields and making adjustments for specific Abiotic and Biotic factors when required could further maximize the performance of your InVigor canola.

It is important to note that a seeding rate of 10 seeds/ft2 is a suggestion based on the research that the Bayer Product Excellence team has done for InVigor hybrid canola, and we are not necessarily recommending an increase or decrease to your seeding rates. Results may vary on your farm due to environmental factors and preferred management practices.
