In particular, the potentiality of this technique to promote the natural accumulation of nutrients into plants deserve to be explored as input saving is strongly recommended in the horticultural sector.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The nutrient solution supplied to a red coloured variety of rocket salad [<jats:italic>Diplotaxis tenuifolia<\/jats:italic> (L.)

Low, medium, and high concentrations of N (i.e., 1, 10, and 20 mM) of the nutrient solution were tested in control (no NTP) or NTP treated conditions in two consecutive growing cycles. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results and discussion<\/jats:title><jats:p>Results highlighted a N-dependent effect of NTP treatment showing a biomass stimulation at 10 mM N while negative effects of this technique at 1 and 20mM N. The biomass boosting of NTP found at 10 mMN coupled with an increase in K and Zn showing positive effects also on the nutraceutical aspects. Interestingly, different mechanisms seemed to be involved in the detrimental effects found at low and high N levels, i.e., a lower sensibility to N deficiency at 1 mM and a synergic negative effect of N and NTP in promoting oxidative stress at 20 mM.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpls.2024.1511335","type":"journal-article","created":{"date-parts":[[2024,12,23]],"date-time":"2024-12-23T06:42:37Z","timestamp":1734936157000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["The effect of plasma-treated nutrient solution on yield, pigments, and mineral content of rocket [Diplotaxis tenuifolia (L.)
