英文摘要	Conservation tillage (CS) is a widely implemented and sustainable agricultural practice. Nevertheless, there is substantial controversy regarding its influence on crop yield and the underlying factors that contribute to these effects. We conducted a comprehensive meta-analysis incorporating 5191 comparisons from 551 studies to assess the global crop yield response to CS. The overall findings indicate that CS resulted in a modest reduction in yield, approximately 1.35 % (P<0.05), P <0.05), compared to conventional tillage (CT). However, this result varied, with no significant yield difference (P>0.05) P >0.05) between CS and CT when strictly following the three principles of CS (no- till, straw mulching, and crop rotation). It should be acknowledged that the relative importance of these three principles varies depending on natural conditions. For example, straw mulching had a greater positive effect in arid regions than no-till and crop rotation. A random forest model analysis identified several influential factors on the relative yield of CS: seasonal precipitation, temperature, soil pH, and no-till duration. For example, CS had negative benefits when seasonal precipitation exceeded 400 mm. Conversely, implementing CS in alkaline soils had significant positive effects (4 %, P <0.05). Additionally, the no-till duration did not always yield absolute positive results; no-till durations exceeding 20 years significantly decreased CS yields (P<0.05). P <0.05). Prolonged no-till may lead to undesirable consequences such as increased soil bulk density, weed infestation, pest outbreaks, and disease, all of which can adversely affect crop yields; therefore, it is recommended that no-tillage be rotated with conventional tillage to minimize the negative effects of prolonged and sustained no-tillage on yields. Furthermore, CS had greater potential for increasing production in tropical regions. In conclusion, adopting regionally adapted CS practices can minimize the risk of yield reduction. Implementing adaptive CS techniques in specific locations can promote global food security and achieve sustainable agricultural development.
