Research was initiated to determine the critical periods of weed interference in soybean [ Glycine max (L.) Merr.] and the minimum weed removal requirements needed to achieve optimum seed yields. In a field infested with mainly broadleaf weeds, a 4‐week weed‐free period after planting was needed to achieve optimum yields in early and late planted soybean grown on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic Argiudoll). Plots cultivated about 3 and 5 weeks after planting required only one handhoeing 2 weeks after planting to obtain optimum soybean yields. Weeds left 4 weeks before removal, but not 6 weeks, did not reduce soybean yields in early or late planted soybean. Results indicate that if soybeans are kept weed‐free the first 4 weeks after planting or if weeds are not left undisturbed longer than 4 weeks after planting, optimum soybean yields should occur.Read More
