Effects of Bacillus subtilis MBI600 applications on tomato plant (cv. Belladonna) shoot (A) and root (B) growth parameters compared to the growth of untreated control plants and Bacillus amyloliquefaciens QST713-treated plants (reference biological treatment). Different letters in the columns indicate significant differences between the treatments according to Fisher’s LSD test (p < 0.05). Vertical lines indicate the standard error of the mean. (C) Bs MB 600-treated (left side) and untreated plants (right side), showing differences in shoot lengths. (D) Bs MBI600-treated (left side) and untreated plants (right side), showing differences in root lengths.
