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.
