Chem fallow was compared to stubble mulch and reduced tillage in a spring wheat-fallow rotation. Average surface residue prior to planting was three and two times greater than reduced tillage for chem fallow and stubble mulch, respectively. Chem fallow plots stored more soil water, but this did not increase yield during the study. During years of crop stress resulting from limited soil water, chem fallow may produce higher yields than stubble mulch. Grain water use efficiency was greater for wheat grown on stubble mulch plots than on chem fallow plots.
