A Disease incidences of banana Fusarium wilt in organic and chemical fertilizer treatments. B Banana yield in organic and chemical fertilizer treatments. C
Fusarium oxysporum density in organic and chemical fertilizer treatments in the three compartments. D, E The random forest mean predictor importance (% increase of the MSE) of bacterial, fungal and protistan community composition for banana Fusarium wilt disease incidence (D) and banana yield (E) in the three compartments. In panels A, B and C, asterisks indicate significant differences as defined by the Student’s t test (***p < 0.001). OF Organic fertilizer treatment, CF Chemical fertilizer treatment. In panels D, E, to estimate the importance of microbial predictors, we used the percentage increases in the MSE (mean squared error). Significance levels of each predictor are represented by *p < 0.05 or **p < 0.01.
