ABSTRACT: Frequency of soil moisture depletion and subsequent crop yield reduction resulting from water use by cover crops is unclear. Effects of cover crop residues and irrigation on soybean emergence, canopy volume, grain yield, and soil moisture in eastern Nebraska were determined Cover crop treatments included five common species and a bare soil control. Precipitation treatments included rainfed conditions and weekly irrigation events of 18 mm (0.7 in) in June and July. Above-normal May rainfall in 1995 and 1996 resulted in similar percent volumetric soil water contents (% VSWC) in the surface 15.2-cm (6.0-in) soil layer. Soybean emergence was unaffected by residue dry ...
