초록/해제  
요약Cereal rye (Secale cereale L.) cover crop has triggered the interest of soybean producers as an integrated tool for waterhemp (Amaranthus tuberculatus [Moq.] Sauer) and Palmer amaranth (Amaranthus palmeri S. Watson) management. Amaranthus spp. pose significant challenges in soybean production regions across the U.S., as they have continually evolved resistance to major postemergence (POST) herbicides commonly used in weed management programs in soybean. The selection of Amaranthus spp. populations resistant to POST herbicides has favored the adoption of preemergence (PRE) herbicides as effective options for early-season Amaranthus spp. control. Understanding how cereal rye can be effectively integrated with PRE herbicides for Amaranthus spp. management in soybean production is fundamental for the success of this practice. Cereal rye biomass production is the most crucial component when cover cropping for weed suppression since it directly impacts cereal rye management strategies, Amaranthus spp. recruitment, and soybean production. Timely cereal rye planting and termination times dictate biomass production by the cover crop. For instance, delaying cereal rye termination until soybean planting (a strategy known as planting green) can effectively optimize biomass production. The increase in cereal rye biomass directly reduces Amaranthus spp. recruitment due to the lower soil temperature fluctuation caused by the cover crop mulch. Yet, the increase in cereal rye biomass also impacts the fate of PRE herbicides by reducing the number of spray droplets that reach the soil during PRE application and lowering herbicide concentration in the soil following application. Nonetheless, there is no evidence that the interception of PRE herbicides by the cereal rye biomass can reduce residual Amaranthus spp. control when cereal rye and PRE herbicides are integrated. Cereal rye biomass can also impact soybean establishment and yield. The thick layer of crop residue from high levels of cereal rye biomass can challenge proper soybean seed placement during planting, particularly under dry weather conditions. The improper seed-to-soil contact can reduce the final soybean population to levels below what the crop can compensate for stand losses, leading to yield reduction. Cereal rye is an effective tool for integrated Amaranthus spp. management programs in soybean production. Nonetheless, understanding the implications of cereal rye biomass on the cropping system is fundamental for farmers to optimize the benefits of cover cropping without facing losses in soybean yield.
