Two other oats trials can be found in the table of tillage experiments. Both compare oats on ridges to oats on flat ground. Tom Frantzen found similar yields between the two practices. Paul Mugge observed a nearly 12 bushel advantage to ridge-till oats, but the trial was not set up for statistical evaluation.
Todd Hartsock continued his comparison of ridge-till and conventional tillage. In 1990 there was a small but significant soybean yield advantage to ridge tillage. The difference in equipment operating costs added to the yield advantage.
