I find it irritating that Canola seed is priced in $ per lb and that the TKW can vary a great deal. I had a salesman call about booking canola seed. With early booking discount of $15/bag, Invigor L140P sells at $14.46/lb. Seed size becomes an issue when the seeds are so large that 5lb/acre is not enough to make the recommended plant stand.
For Example,
Assuming the TKW is 6 grams, actual seed in the bag is 95% and seedling survival of 80%, to make a stand of 10 plants per acre you need 7.5 lbs/acre ($108/acre).
That would be fine if every seed survived and every stem was 3/4" across but that is not the case. Plant performance is not always great and its always someone else's fault (never the seed company's).
