Title: Weed Control in a Low-Till Oat (<i>Avena sativa</i>) - Soybean (<i>Glycine max</i>) Rotation
Abstract: Early-preplant herbicide application for uncultivated production of soybean [ Glycine max (L.) Merr. ‘Williams’] slot-seeded into untilled oat ( Avena sativa L. 'Stout’) stubble was studied. Foliar- and soil-active herbicides were applied to stubble of recently harvested oats to control weeds without tillage so that soil moisture could accumulate during the fallow period. The following spring, five herbicide treatments were applied 0, 2, 4, and 6 weeks prior to soybean planting as well as preemergence to control weeds selectively in uncultivated soybeans. Broadleaf weeds were more effectively controlled than grass weeds, but both were controlled adequately with several herbicide combinations and at all five application times. Selective control of weeds was sufficient to eliminate yield loss of uncultivated soybeans seeded into untilled oat stubble. This production method could provide the Great Plains soybean producer with an effective weed control system while conserving soil, soil moisture, labor, and fuel.
