Abstract
Abstract Reduced tillage systems are being developed for the Great Plains that conserve limited moisture in order to improve soybean [ Glycine max (L.) Merr.] cultivar response in this region. Fourteen soybean cultivars were grown in narrow rows using herbicides or tillage for weed control during the fallow period after oat ( Avena sativa L.) harvest on an oat‐soybean rotation. Experiments were conducted at Concord, NE on a Colo silty clay loam (fine‐silty, mixed, mesic, Cumulic Haplaquolls) and at Lincoln on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic, Typic Argiudolls) during 1979 through 1982. The best broadleaf weed control occurred with ‘Gnome’, ‘Century’, ‘Weber’, and ‘Williams 79’ cultivars; also Gnome and Century had the best grass control as well as the lowest total weed yields. Early triazine injury was least (<30%) in Gnome, ‘Beeson 80’, ‘Elf’, ‘Wells II’, Weber, ‘Cumberland’, and Century. The highest yielding cultivars were ‘Mead’ and Century. Soybean cultivars generally yielded better on tilled vs. herbicide treated oat stubble, but the three cultivars showing the least difference in yields regardless of the prior fallow treatment were Cumberland, Beeson 80, and Weber. Cultivars selected for reduced tillage methods may differ from those used in conventional production systems.
