| Abstract: | Two seasonal pot experiments were conducted to investigate the effect of biofertilizer application after mixture of lime and ammonium bicarbonate (LA) fumigation, on banana Fusarium wilt disease suppression and soil microbial community composition. Biofertilizer application after LA fumigation decreased 80% of disease incidence compared to control of biofertilizer application to non-fumigated soil. Biofertilizer application after fumigation clearly manipulated soil microbial community composition as revealed by non-metric multidimensional scaling and Venn diagram. LA fumigation significantly reduced the abundance of F. oxysporum while biofertilizer application after fumigation could further decrease it. Furthermore, indigenous microbes, e.g., Bacillus, Pseudomonas, and Mortierella, were associated with disease suppression. Biofertilizer application after fumigation significantly (p?F. oxysporum by general suppression resulting from manipulated soil properties and recovered soil microbiome. |
