? 2021 Elsevier B.V.In this work, we investigate the changes in Mentha aquatica var. citrata (bergamot-mint) characteristics and essential oil composition regarding the modification of the amended dose of Olive Mill Wastewater (OMW) in pots at three different doses; D1 = 9 ml/100 g, D2 = 22.5 ml/100 g and D3 = 54 ml/100 g of soil, seven months before plantation of bergamot-mint cuttings. OMW application didn't affect plant biomass production (leaves, stems, roots) and chlorophylls in the leaf, while the amount of leaf phenols showed a dose dependent increase. Bergamot-mint essential oil major compound is linalool acetate for control, trans-pulegol when OMW is applied at 9 ml/100 g, isopulegyl acetate when OMW is applied at 22.5 ml/100 g, and verbenone when OMW is applied at 54 ml/100 g. When OMW was applied to soil at doses D1, D2 and D3, some of bergamot-mint essential oil compounds such as decanone, citronellol, piperitone epoxide, guaiacol acetate, methyl cinnamate and citronellyl propanoate, totally disappeared. OMW spreading at 9 ml/100 g allowed appearance of menthone in Mentha aquatica var. citrata essential oil while menthol and terpineol appeared only when OMW was applied at the high dose 54 ml/100 g.
