Canola seeding depth

It will probably come up if it doesn't have to fight with a big mess of straw on the surface or crusting, probably at a reduced rate though. What seeding rate? If you have erratic depth some may be shallower...

Sometimes if a guy seeds at 4-5#/acre a mess up like this and a reduced plant stand is a good way to see how few plants will make a good canola crop.

We all screw up, welcome to the club!

What is the seed size? In my experience the bigger the seed the better chance it will come up if planted to deep.. I had some come up from 3 inches last year on a part of the field that was worked pretty black in the fall.. bigger seed tho it was right around 6 tkw if I recall correctly

At least you don't have to worry about it freezing off for a bit.  By the time it comes up the cold nights should be over.
Volunteer canola would easily survive under those conditions! lol

Even if half comes up he still has 1.6#/acre which amounts to over 4.1 plants per square foot which IMO is more than enough. BASF will probably say you need at least 6 but I disagree and here is why:
In 2017 I had a field that was seeded into okay moisture but no rain for a bit so some seeds germinated and died. It was the poorest stand I had had in some time, but I had never re-seeded a crop before and was not about to start, so I left it. It was L140P Lumiderm treated I believe. Now the field progressed and at fungicide time I sprayed about 2/3 of the half section and quit because I didn't think it was thick enough. I don't remember how the year went specifically but I think we had a good growing season with adequate rainfall. The field did about 84 looking back at records and some parts were sustained 100-120 on the monitor and that was the thinnest part of the field at about 2-3 plants/ft. I couldn't believe it. 

So when someone says to rip up a field because of a low plant stand I say even if it's thin but even it still has good potential. Just keep the weeds out of it. Here is some pics of that crop and stubble.

I had some get chewed by flea beetles badly last year and had 0-2 plants per square foot. Rep was out and said to reseed but I decided not to as recommended by guys on the forum here. Was not nice to look at but ended up yielding 75% of average and grade was number 1 and in the bin 2 weeks before neighbours who did reseed. Of course last fall was a beauty so everybody had lots of time but normally those two weeks could a been a deal breaker. Tough to say about reseeding due to a depth issue as soil is different in every area but I think I’d leave it a bit and see what happens.

I made this same mistake too. But on 1000 acres. Same thing, I don't make that mistake. Pretty careful about stuff like that (depth, calibration, seed loss etc). Four different varieties and the one with the biggest seed (7.6 tkw) looks the worst. Thinnest by far. Hope you guys are all right about thin plant stands on canola. By contrast, neighbors across the road has 12-15 plants a foot. Will be curious on it yield vs mine.
