Canola seeding rates

Seeding with Dutch 2 inch spread tips, not 3/4 inch knives. Slow speed helps from chucking the dirt on the first and second rows....more of a soil "flow" around the opener.

Glad you brought up the air velocity point. We don't blast it down the pipes either. Usually try to give it enough to carry it. Better to slow it down than blast and bounce at the opener.

In my early years/30 years ago I remember reading that 3-17 plants per acre made no difference in yield. In the last few years 3.5-7 lbs per acre made no difference to me. Only one year with damping off from cold soil.
When it comes to soy beans I personally think that air velocity and handling could play a big roll in seed vitality. I use a conveyer auger filling my drill, I have a small drill so the seed doesn't have to travel very far with less air. Wondering if this is why I have more plants seeded at the same seeds per acre as niebours?

I seed 4.5 to 5 pounds. I lose lots to bugs above and below ground. This year it is coming up a bit thick though. They say a viable crop is still only 1 plant per square foot. I seeded too deep once and had that, but still got 55 bushels an acre with 45H21 years ago.
