I'm not a row cropper but I do raise a few acres for cattle feed.
When no-til started around here it was for reducing cultivation and helping to eliminate erosion, this required some type of herbicide to kill the cover crop and help control weeds.
The first few years of no-tiling dad had a set of small cutter disk on our cultivator to cut and throw dirt up around the corn stalks coving any grass near the roots.
Over 90% of the yield increases I've seen was from higher seed population and better nutrient management.
I remember playing 38" rows with 14000 per acre population, when we narrowed up the planter to 30" rows population jumped to 18-19000 with the same seed spacing, that extra 4-5000 ears of corn really picked up the yield.
Now we planting 24000 per and with proper nutrient applications yields have doubled from back in the day.
I heard that in good crop ground their putting out 28000 plus populations.
Weeds take up some of the nutrients that was intended for the crop so I can see a small percentage of yield lose due to weeds.
I think the bigger lose would be from dockage in the price due to foreign matter in the grain harvested from a weedy field.
Just my .02, like I said I'm not a grain farmer so I could be completely wrong.

It would be a great day for the collies and the terrier dogs, rats and mice would be at the bottom of the stacks so the dogs, would have a busy time hunting and killing, all the corn was gathered and ricked in what we c
