Introduction The non-thermal plasma (NTP) technique has been suggested as a sustainable horticultural practice to promote biomass accumulation, nutrient uptake, N metabolism, and disease prevention in plants. In particular, the potentiality of this natural accumulation nutrients into plants deserve be explored input saving is strongly recommended sector. Methods solution supplied red coloured variety rocket salad [ Diplotaxis tenuifolia (L.) DC. ‘Dragon’s Tongue’] grown hydroponic close loop system was treated with NTP. Low, medium, high concentrations (i.e., 1, 10, 20 mM) were tested control (no NTP) or NTP conditions two consecutive growing cycles. Results discussion highlighted N-dependent effect treatment showing stimulation at 10 mM while negative effects 1 20mM N. boosting found mMN coupled an increase K Zn positive also on nutraceutical aspects. Interestingly, different mechanisms seemed involved detrimental low levels, i.e., lower sensibility deficiency synergic promoting oxidative stress mM.
