## 4 Conclusions  
The results of the present study clearly demonstrate the importance of implementing specific cultivation management practices for MOWP to enhance the TAC of plant extract, with potential inherent health benefit implications. Accordingly, this study highlighted that, for _Silbyum marianum_, the hydroalcoholic extract exhibiting the highest TAC was obtained under conditions involving the application of PGPR, no fertilization with P\({}_{2}\)O\({}_{5}\) and K\({}_{2}\)O, and full irrigation at field capacity (condition SM101). In the case of _Achillea millefolium_, the antioxidant activity of its hydroalcoholic extracts was maximized under \begin{table}
