Simulating synergistic effects of climate change and conservation practices on greenhouse gas emissions and crop growth in long-term maize cropping systems

Summary

• Future climate under RCP 8.5 increased greenhouse gas (GHG) emissions in the corn field. • Future climate under RCP 8.5 decreased corn yield and biomass. • Temperature, [CO 2 ] atm , and precipitation were the main climatic factors affecting GHG emissions and corn growth. • Stover retention and tillage increased CO 2 and N 2 O emissions. • Corn growth was not significantly affected by long-term conservation practices. Understanding the impacts of future climate change and long-term agronomic practices on environmental quality and agricultural productivity is critical to the development of sustainable agronomic management approaches. Given these requirements, the present study’s objective was to evaluate the potential impacts of climate change and long-term conservation practices on green
