Cereals will do better on narrower spacing. That is just a reality. Canola can do well on wide or narrow spacing IMO. Plants per ft2 regardless of spacing is key. 3lbs on narrow spacing puts plants in the row further apart allowing space around the entire plant. Put 3lbs on 15' row spacing and only space on 2 sides of the plant. I am not sold on the wide spacing canola theory. Floating gives the best plant ability to expand but germination is sacfriced with varying seed depth and without moisture soon after can be a wreck. Here in the NE though many thousands of acres are still seeded this way with great success most yrs.
