Technical Abstract: Reports on the long-term effects of tillage and cropping systems on corn and soybean yields are limited. Yields have been measured in a long-term experiment (30+ years) with three cropping systems [continuous corn (CC), continuous soybean (CSB), and soybean-corn (SB-C)] in six primary tillage systems (chisel, disk, plow, no-till, ridge-till, and subtill) under rainfed conditions in southeastern Nebraska. Average yields for corn and soybean were not statistically different between tillage systems, but both corn and soybean yields in rotation were significantly greater that those in monoculture systems. Results of these analyses will be presented and discussed.
