Planter / drill

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

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

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.

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

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.

That will be interesting for sure .
Corn needs at least 5 in space between seeds to produce good cobs . The 75-80.% feed value comes from good mature cobs not just plants

We and many of our neighbors plant our irrigated canola on 22" spacing. There is no yield hit compared to an air drill with narrower spacing. We seed at 2lbs, rather than 5 with the air drill.

On dry land, we have seen a yield hit. At the wider spacing, the plant needs to flower/branch longer. If it's short of water at that time, it won't branch enough to make up for the wider spacing

Ya this shitty Seedmaster has to hit the road too. Total trash.. 3.9 Ibs (4.5 tkw) ... 375# fert at 4.8mph... no fert seed placed..no rain yet 😢... Did some crosshatch 45 deg trials with 12" spacing a couple times already over the years.. No yield increase in cereals. Decreased yield in lentils.. Zero difference in canola..

Interesting comments on row spacing. Things do change but i used a 12" machine single row for 2 yrs and did not like it.
Every plant on earth has an optimum density. My planter comment was regarding not only the independent opener aspect but precision metering and gravity drop of seed.
Very evident in my soybean plot this year. 1 bushel the acre shows to me at least the limitations of air delivery systems from one auger.
Not to mention the funky stuff that can be done when each opener unit computer controlled.
However, I'm not a gaurenteed pay guy so I could be full of shit.
Nice pics guys.

Looks great JD
This is totally not about not what's better or not as a seeding tool
Let's not be pig headed farmers here
I was just sharing info that others might find interesting..... or not
There are tremendous air drills out there , and yes Tweety ours is not the greatest for canola . I do not need to be ridiculed on that asshole . But I will send pictures if you wish of all the crops seeded with that outfit and data for the 8 years we ran it do far. Trust me , it's done more than ok over the years. I will pm you if you want them.
Just trying to share info to those who may find it interesting.
Never once , ever , did I say it was better than anything else . Just sharing info
As far as being years behind , you may want to pull your head right if you Ass
