Planter / drill

We solid seeded last year with a Bourgalt airseeder at 30,000 plants and cobs were great. Seeded at 28,000 this year with the planter. We'll see how it does.

Check the cobs when you do that
I think we could go to 20 in
But that also would depend on plant populations.

12 in spacing in corn would never get a mature cob in this part of the world .
Is all that research you quoted from north west Sask ??

Actually the narrow row yield increase in corn (15" vs 30") is more consistent the further north you go in the US. That is to say the shorter growing seasons encountered in Michigan and Minnesota are where the most benefit is seen. If distance apart is the objective 15" rows give you that better than 30". Think about it - the rows may be 30" apart one way but the plants are 6" from each other in the row. With 15" rows you can seed 12" apart in the row - more space, better canopy, less weeds.

Canola not so much , unless you sole intent is selling seed and fungicide . Then ya , keeping seed rates higher on narrow row spacing is a win win for you. Not so much for the grower

As far as wheat or winter wheat most of us have known for many many years that narrower row spacing is key for higher yields . That's been proven for 30 plus years .... almost everywhere

We are talking canola , not wheat .
No one in there right mind would use 15 in space around here in wheat , let alone a planter

Tweety you just don't get it...it isn't the info you present, that is fine.....it is the ignorant, unnecessary jabs you make....you must be an interesting neighbor if you farm.

“What we found was that yield declined linearly when you went from nine-inch row spacing to 24-inch row spacing. Even under optimum conditions of good soil fertility, very good weed management, sometimes even hand weeding of plots, good flea beetle control and little disease pressure, we saw declining yields with wider row spacing,” says Randy Kutcher, with AAFC at Melfort, Sask., when he conducted the trials (Kutcher is now with the Crop Development Centre at the University of Saskatchewan). Declining yields were especially the case with the 18- and 24-inch row spacing. Differences between the nine- and 12-inch row spacings were more limited.

If you do careful measurements and follow a good fair protocol, its consistent. Or you can believe a "feeling", then row space doesn't matter.

So as usual, get called a troll. Show some peer reviewed science where row spacing doesn't affect yield, where yield improves with a corn planter....

Why not just get one of these ordered [URL="https://www.realagriculture.com/2017/06/techtour-manitoba-farmer-gives-planters-a-new-look/"]https://www.realagriculture.com/2017/06/techtour-manitoba-farmer-gives-planters-a-new-look/[/URL]

Sounds like what i'm after Klause, i'll have to investigate. thanks.
