No significant differences between the control and biocontrol treatments were observed in rice yield or soil physicochemical properties. Metataxonomic analysis revealed 17 bacterial phyla across all samples, with no significant differences in the overall microbial community structure between treatments at any time point. On the other hand, significant changes in microbial beta-diversity over time within the same soil treatments suggest that temporal dynamics, rather than the biocontrol treatment, drive shifts in microbial community structure.
