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.
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.
Factors that affect survivability
6 Plants/ft2 (stubble count)
10 Seeds/ft2 (seeding rate)
= 60% 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.
