Abstract

Grain sorghum (Sorghum vulgare Pers.) was grown in combination with varying densities and durations of yellow foxtail (Setaria glauca (L.) Beauv.) during 1963-1965 at Manhattan, Kansas. Weed yield and competitive influence were greatest during the year of above-average rainfall and supplemental N fertility. Reduction in sorghum grain yield was due principally to a reduction in number of seeds per head. A 16-inch weed band on the crop row reduced soil moisture more than any other density treatment, but lesser weed densities reduced soil moisture below that of weed-free plots.
