David Hula captured top no-till yield honors in last fall’s National Corn Growers Association contest with a yield of 319.3 bushels per acre. While this Charles City, Va., no-tiller’s result was about double the current national average, 300 bushels is a yield some industry leaders are anticipating as being typical just 20 years from now.

Having no-tilled since 1972, Paul Schaffert has learned a few things while growing corn, wheat, soybeans, sunflowers, milo and grain sorghum on a 2,000-acre irrigated and dryland farm in Indianola, Neb. The lessons have come even harder recently, because the area, which normally receives 10 to 17 inches of rain each year, has been suffering through a drought for the past several years and irrigation is now restricted to 13 inches per year.
