摘要： Organic agriculture has the potential to contribute to environmental conservation, although its impact varies depending on management practices. To investigate the effects of no-tillage (NT) combined with a rye (RY) cover crop on energy efficiency and carbon footprint (CF) in soybean production, a four-year experiment was conducted. Three tillage methods [moldboard plowing (MP), NT, and rotary tillage (RT)] and two cover crop treatments [fallow (FA) and RY] were compared. NT had 39.6% and 34.0% lower energy input compared with MP and RT, respectively, due to reduced fossil fuel consumption. However, NT also showed decreased soybean yield compared with MP and RT. Nonetheless, RY cover crop management mitigated yield reduction in the NT system, with the yield of NT-RY being 20.4% higher than that of NT-FA, although not significantly different. NTRY exhibited the highest energy use efficiency, with high energy outputs from yield and low energy inputs. Moreover, NT-RY resulted in a 3.5% increase in soil organic carbon stock, offsetting total carbon dioxide (CO2) equivalent emissions, leading to the lowest CF (-1892.99 kg CO2 eq ha-1) and yield-scaled CF (-1.44 kg CO2 eq kg-1) among all treatments. Therefore, NT-RY management, with its high yield and energy efficiency and low CF, has the potential to be an environmentally friendly and sustainable cropping system for achieving cleaner agricultural practices in organic farming.
