Corn yield increased approximately 10% (23 bu/acre) from the lowest to highest irrigation capacity in these four years of varying precipitation and crop evapotranspiration. Strip tillage and no tillage had approximately 8.1% and 6.4% (18 and 14 bu/acre) greater grain yields than conventional tillage, respectively. Results suggest that strip tillage obtains the residue benefits of no tillage in reducing evaporation losses without the yield penalty sometimes occurring with high residue. The small increases in total seasonal water use (< 0.5 inch) for strip tillage and no-tillage compared to conventional tillage can probably be explained by the greater grain yields for these tillage systems.born digitalCD-ROMsproceedings (reports)engCopyright and other restrictions may apply.
