Conventional tillage is the most common practice in the Hulunbuir region; however, it may harm the soil's physical properties. Reasonable tillage methods can improve soil physical and chemical properties and create a good soil environment for crop growth. The objective of this study is to analyze the effects of 10 sets of tillage methods on soil capacity, soil moisture, agronomic characteristics, and the yield of spring maize (Zea mays L.) fields. The results derived indicate a reduction in soil bulk density under tillage methods T2, T3, T4, T7, and T8. While the effect of individual tillage methods on specific agronomic characteristics of maize was minimal, variations in tillage practices did significantly affect the mechanical harvesting attributes of the crop. Specifically, the combined treatments of T6 × N2 and T8 × N2 demonstrated a higher net income per hectare across both the 2019 and 2020 growing seasons. The experimental findings evidently demonstrate the effectiveness of two specific tillage methods for implementation in the Hulunbuir region: T6 × N2 (deep rotation with stubble clearing and straw returning) and T8 × N2 (deep tillage combined with comprehensive straw crushing and returning). These practices were beneficial in their capacity to augment soil organic matter content while simultaneously enhancing the stability of soil aggregates.
