I always made more money with yellow mustard than canola. I grew Andante, because that's what I had. Seed rate of 16lbs cleaned bin run, 90-115 lbs N depending on soil test, 25lbs of S, starter N and P. Weed control was edge which needs a lot of harrowing if it is going on cereal stubble and a heavy dose of glyphosate pre-seed. Once the mustard was seeded I was done until combining. Nothing ever ate much of it, not enough to pay for spraying. Straight cut it, air in the bin and sell it picked up in the yard.
I always sold to Viterra and was never disappointed with the grading or dockage. I always got paid for what I put in the truck, lower quality was lower grade and higher quality was higher grade.
My rule for pricing is that if it was 19/bu or below don't contract and 19/bu or above contract it.
The seeding rate I used is much higher than recommended but when I started I had no idea what I was doing so did a bit of everything to see what worked and 16lbs worked.
