Also, instead of just some random strips we have planted half of the acres each way. I'm certain that this will be a much better test.
Actually, hate to say it Todd, but split fields are generally a poor way to evaluate a practice. You were better off with random strips.
I've been planting skip row now for 3 years and while I think it has merit here............one of the things that makes me question it is that I have spent time with a ground probe the following spring after harvesting the skip row stuff and I have found more moisture in the skipped area. While that is good for the next crop...........I can't help but wonder if I deprived that growing crop of needed moisture??
In my 3 year study at Tribune where we were measuring soil water across the cross-section, that was really the issue with plant 2 skip 2, it was too defensive and was costing us yield. This was due to leaving too much water on the table at the end of the season. P1S1 and P2S2 did a better job of extracting everything. Of course the great unknown is how much hybrid selection (and a given hybrids's root architecture) could effect this . Bob Klein at UNL advocated coming back the next year and planting skip-row row crop back into the prior year's skips.
