Abstract

Corn was grown in soils containing root residues of giant foxtail (Setaria faberii Herrm.), yellow foxtail (Setaria glauca (L.) Beauv.), and crabgrass (Digitaria sanguinalis (L.) Scop.). The effect of these residues on corn root growth was studied using a new technique which measures root response to soil properties with a single plant. Giant foxtail was the most inhibitory. Implications of these data are discussed in terms of the dominance and competitive ability of giant foxtail.
