Microbial α-diversity in rhizosphere. Shannon index and observed species of rhizosphere (A) bacterial and (B) fungal communities of two potato cultivars MONI and HERBST grown either in soil with natural (NSM) or disturbed (DSM) microbiomes were compared between continuous watering (blue) and reduced watering (red). Boxplots display the medians, tops and bottoms of the boxes represent 75th and 25th quartiles, and whiskers outside this range; dots illustrate the individual observations in each sample group. A non-parametric Wilcoxon test (p < 0.05, n = 5) was applied to calculate significant differences across sample groups and numbers above the boxes indicate the corresponding p-values
