Wheat variety yield in 15-inch rows What will 15 inch row wheat
yield? Because some Ohio wheat producers are interested in
growing soft red winter wheat in 15-inch rows in order to
utilize a more precise planting implement, reduce equipment

(done when wheat is headed out), sow cover crops or establish a
forage crop; wheat yield in a 15-inch row is important in
evaluating any row spacing change. click image to zoom Research
done by Beuerlein & Minyo in 2008 with 3 wheat trials found 7.5
inch row spacing to out yield 15 inch row spacing by about 7.2 %
or 6.6 bushels per acre (bu/ac). Read this research report. In
2009 and 2010, Lee and Herbek, of the University of Kentucky,
grew three varieties of wheat at two locations in 15-inch and
7.5-inch rows. Varieties tested were known to be prolific
(varieties produce a lot of tillers). Yields ranged from 70 to
just over 120 bu/ac. In two of the environments, there were not
any differences in yield between 15-
