Resumen
Descripción
Climate resilience refers to the capacity to improve soil fertility and water storage while maintaining stable crop yields. Conservation tillage practices, such as no-tillage and crop rotation, are recognized as effective strategies for enhancing climate resilience. The objective of this study was to evaluate the effects of tillage practices (notillage and rotary tillage), and cropping systems (continuous maize, soybean-maize-maize rotation and maizesoybean rotation) on crop yields, growth dynamics, soil fertility, and soil water storage. Then we explored the influence of key indicators on yield performance. No-tillage (NT) increased maize and soybean yields by 4.54 % and 7.45 %, respectively, versus rotary tillage (RT). Legume rotation also boosted maize yields by 3.56 % compared to continuous maize (MM). Yield stability was assessed against precipitation variability during the four-year study. Maize yield CV (coefficient of variation) under NT with legume rotation was < 50 % of RT and MM systems, while increasing soil fertility by 12.49 %. Yield stability was directly linked to biomass accumulation and soil organic matter, which positively influenced yields. Integrating NT with legume rotation enhances soil fertility, stabilizes yields, and strengthens climate resilience in Northeast China, providing an effective strategy for sustainable agriculture.
