Brief, among the soil variables used in SEM model the soil C/N (H1) and soil water retention (H2) are the key factors contributing to high maize yield in NT and RT. However, there are still substantial unresolved variations (23%) that limit our understanding of how tillage practices affect crop yield.
Therefore, further studies, such as monitoring the occurrence of the diseases and
pests, may be needed in order to select the appropriate tillage management strategies for improved crop production in the region.
