Factors Affecting Use of Minimum Tillage for Corn1

D. M. Van Doren, Jr. and Gordon J. Ryder2

Synopsis: Use of minimum tillage resulted in an average of 4.8 bushels per acre more corn than use of conventional tillage. Low yield levels and low rainfall combined with high degrees of land slope tended to increase this difference. Weed control practices, conventional seedbed preparation, soil surface texture and internal drainage, and previous crop had no effect on the yield difference between the tillage systems.
