Need to compare air drill on 12” to planter on 12”

If the image shown at 11:35 is how they had their row spacing trials laid out, there is no way to get reliable yield information out of that trial and the data they did get will artificially make the 12" spacing look better than it really is.

That image was stitched for presentation purposes.

@@kencoles828 The problem isn't how the plots are oriented to each other, the issue is the plots are different width and the circumference of the plots isn't equal. The plants on the borders of each plot are going to have access to more nutrients/water than the plants in the middle of the plot. When your ratio of border plants to interior plants is different, you can't compare the yields of those plots.

[@kencoles828]

The raw plot yield is adjusted for area according to row spacing. An excess of nutrients were applied to isolate row spacing effect.
