Nutrient and Nutraceutical Quality of Rocket as a Function of Greenhouse Cover Film, Nitrogen Dose and Biostimulant Application

The nutrient and nutraceutical quality of greenhouse wild rocket is strongly influenced by the light environment nitrogen fertilization. We investigated effects two cover materials, a diffuse film (Film1) traditional clear (Film2), three regimes, no N supply (N0) sub-optimal (N1) optimal (N2) doses, also in combination with biostimulant (Stimolo Mo), on mineral composition, antioxidant properties chlorophyll carotenoid content plants grown autumn–spring cycle. leaf concentration most minerals was higher under Film1 compared to Film2. In general, K, Ca, Mg Na were higher, S lower presence supply, addition promoted uptake. Under Film1, hydrophilic activity (HAA) some harvests, ABTS (ABTS AA) first one, while always afterward, than Nitrogen fertilization did not affect activity, it reduced total phenols ascorbic acid. application increased AA at dose unfertilized plants. Both inhibited synthesis acid, chlorophylls. experimental treatments exerted variable over time significant interactions harvest period found for many parameters.
