e0“The effect of no-tillage (NT), chisel plow (CP), and moldboard plow (MP) treatments on plant density and grain yield was measured from 1981 through 1990”
e1“No statistically significant yield differences among tillage treatments, when averaged over the 10-year period covered by the experiment, were detected”
e3“Long-term comparisons of alternative tillage systems are needed to evaluate their effect on corn (Zea mays L.) yield under the variable temperature and rainfall conditions of the Corn Belt”

- Association Grain yield decreased by approximately 0.3 Mg ha-1 per cm of weighted water stress above 8 cm.
- Association Over half of the yearly differences in grain yield between tilled and no-tillage treatments was explained by differences in plant density.
- Association Grain yields for all tillage treatments were primarily affected by water stress.
