Climate, Rotation, and Tillage Impacts on Soybean Yield Gains in a 50-Year Experiment.

ABSTRACT: Understanding how interactive management practices and climatic behavior influence soybean [Glycine max (L.) Merr.] productivity is imperative to inform future production systems under changing climate. This study examined eight unique long-term production systems from 1975 to 2024 on a fertile rainfed Mollisol in Indiana, USA. Using this 400-unit field-scale dataset comparing soybean in monocropping versus following maize (Zea mays L.) across four tillage intensities (Moldboard Plow, Chisel, Ridge/Strip-Till and No-Till), we investigated how these practices interact with each other and with weather patterns. Our focus was on the spring (1 April-20 June) and summer (21 June-30 September) periods, and their effects on final yields and morphometric plant phenes. Soybean yield results during
