Choosing a Seeding Rate for Canola

 

~Today’s Blog is brought to you by Dwight Willoughby, P Ag   CCSC

Planting Canola

The Canola Council of Canada recommends choosing a seeding rate based on seed weight and the estimated seedling survival. Canola seed size is measured in grams per 1000 seeds, typically the range varies between 3 to 6 grams /1000. This is important to consider when seeding pounds per acre, if a farm plants a heavier seed there will be fewer plants per acre.

The survival rate of canola seedling must be considered for your farm. Targeting a plant stand depends on the farm’s tolerance of risk. A 50% seed survival rate is common; keep in mind a margin for plant death due to disease, frost, insects or other factors. Targeting seeding rates should be adequate for 7 to 14 plants per square foot. Using the 50% survival rate this would translate into planting 14 to 28 plants / foot.

Use this formula to set a seeding rate based on seed size:

Seeding Rate (lb./ac.) = [9.6 x desired plant density (plants/ft2) x TSW (grams)] ÷ estimated seed survival (%, expressed as a whole #)
