Abstract

Sorghum grain yield losses in Northwest and Central Texas caused by uncontrolled weed growth varied from 8 to 41%. Under high moisture conditions, sorghum competed best with weeds when planted thickly in narrow rows. With less moisture, seeding in wide rows resulted in more effective competition. If rains produced weed germination immediately after planting, competition with the sorghum was more severe than when weeds germinated 1 or 2 months after sorghum planting. Several mechanical weed control methods were very successful.
