I've been reading a lot of research and experiences of farmers in the US with seeding corn at 15" versus 30" and getting better yields. Makes sense to me as 12" by 15" is better spacing than 6" by 30" in terms of equal room to grow. Had our corn custom seeded with a planter in 30" rows this year but wish i'd read the research earlier - especially as ours will be grazed so corn headers aren't an issue.
I'd love to be able to seed corn on 30" rows and seed hairy vetch down the middle but I guess the planter that did ours wasn't designed to do that?

hey farma most guys here in oz love rogators almost deemed to be the rolls Royce of sprayers.
ps I don't own one never been in one

“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]

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

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 ??
