Be sure to check your seed size for your canola seed. Seeing some very large TKW numbers which unfortunately means you need to seed more lb/ac.
Have an example of 5.25 gm/1000 kernels which is actually fairly large seed on the scale for canola. So unfortunately increases cost. Should be sold on seeds/bag.
So plant stand target is 7-14 plants per sq ft of established plants. So that is 304 920 to 609 840 plants per acre. Estimate 40% loss on emergence need to drop 508 200 to 1 016 400 seeds/ac. 40% is actually a success and would represent optimum seeding conditions. Losses are often higher.
Using a real target of 10 plants per sq ft. Need to seed 726 000 seed per acre. 8.4 lb/ac for this target and seed size. I have attached an article with charts to demonstrate the relationship.
