Abstract
Corn ( Zea mays L.) and soybeans [ Glycine max (L.) Merr.] were grown for 5 yr in rotation without tillage (no-till), with fall and spring tillage (disk), and with conventional tillage (plow). Weed distribution and weed yields were measured in the final year of the experiment. Grass weed yield, primarily due to green foxtail [ Setaria viridis (L.) P. Beauv. ♯ SETVI], was significantly higher in the no-till system. Broadleaf weed distribution and yield were similar in all tillage systems.
