| Interesting study. Here are the results I had this year. I have tested PB going back to 2019, with varying results, mostly depending on weather conditions. I used varying amounts of N like you did, and tried the 40# reduction. My best luck was using normal N rates and just putting on top. In the chart I used 160# of N as urea in the spring, no sidedress. This was a fairly simple plot, side by side, one half the planter with, and the other without. Not claiming to be super scientific, but I always try to replicate, at field scale. Feel free to reach out, I have a power point I'd be happy to share with you and get your feedback.
