The stability of maize production in Northeast China where rain-fed agriculture is widely practiced faces serious challenges due to climate change. Therefore, to investigate how the mechanisms of conservation tillage affect maize yield, a 4-y study (2018–2021) with two planting densities (60,000 and...
