Plant growth parameters. (A) root length (B) stem height and (C) leaf dry weight of two potato cultivars MONI and HERBST were compared between native soil with natural microbiome (NSM, turquoise green) and autoclaved soil with disturbed microbiome (DSM, brown) under continuous watering (CW) and reduced watering (RW). Horizontal bars within boxes are the median. The tops and bottoms of the boxes represent 75th and 25th quartiles, respectively. The two vertical lines outside the boxes represent the whiskers. The colored dots stand for the individual observations. 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 statistical p-values
