NW Washington | Some research on 15" wheat has been done at Ohio State, but I don't know how well that translates to your growing conditions.
http://extension.osu.edu/~news/story.php?id=4238 You should be able to google up more info too.
Dryland wheat is routinely planted in 14" rows in the Pacific NW, but in this case moisture is always the limiting factor for yield. Ten and 12 inch rows do not seem to reduce yields but 15" maybe going a little too far. | |
