NC Iowa
I'm right on mn border all nitill. I did a couple trials in 23 and 22. The 30" won anytime yield was over 55. If you have a really stressful/ dry year, the 15s do a little better like we had in 23. We have WM ready in every field, usually doesn't get to bad in notill but still think that's part of the difference.
In high yield environments 65+, seemed the 30"s had a clear advantage.
