Corn (Zea mays L.) grown under the no-tillage system was compared with that grown under (1) systems involving increased amounts of tillage for 2 years, and (2) conventional turnplow tillage over a 6-year period. Plant growth and yield of corn generally increased with decreasing degrees of tillage in the 2-year test. Yields from no tillage during the 6-year period were comparable to or ranged from 18 to 39% above yields from conventional turnplow tillage. Soil moisture measurements indicated that the dead sod mulch provided by the no-tillage procedure was highly effective in reducing evaporation and runoff from the soil surface.
