“…The HI system plants were characterized by a slower growth, especially at the beginning of the cycle, and this led them to a lower yield than the control. This result is in agreement with Cannazzaro et al [16], where the high-intensity NTP was applied without interruption in soilless lettuce cultivation. The authors found a lower yield, together with an increase in the dry matter.…”

“…Only sodium showed a decreasing trend with the increasing intensity of NTP treatment. These results were also found in the study conducted by Cannazzaro et al [16]. The concentrations of organic nitrogen, nitrate, potassium, calcium, magnesium, phosphorus, manganese, and iron in gerbera are higher in those fertigated with nutrient solution treated by the non-thermal plasma.…”

“…The experiment was conducted at the experimental farm "Lucio Toniolo", University of Padova, Northeastern Italy (45 • 21 N; 11 • 58 E; 6 m a.s.l.). The cultivation of two lettuce (Kerlis cv) crop cycles was considered: the first from 21 October to 14 December 2020 (57 days) and the second one from 5 March to 16 April 2021 (43 days). The main climatic parameters during the greenhouse crop cycles are shown in Table 1.…”

“…NTP can be a good alternative to conventional treatments, such as chlorine, heat, or ultraviolet light, which have good antimicrobial functions. Furthermore, recent experimental approaches have also considered the opportunity to apply NTP to ornamental species always cultivated in closed-loop soilless systems [15,16]. NTP turns out to be a treatment that can promote the growth performances of the plant.…”

“…More precisely, NTP can induce the formation of nitrate (NO 3 − ) and ammonium (NH 4 + ) through the oxidation and reduction of molecular nitrogen (N 2 ) after its dissociation; this could support the global demand for nitrogen by offering a more sustainable response both from the economic and environmental point of view [17]. The results available so far on the application of NTP in the soilless cultivation of vegetables are still limited, often with inconsistent responses in relation to the species used [15,16]. The main aim of this research is to evaluate the treatment of the nutrient solution with NTP in the cultivation of lettuce using the nutrient film technique, one of the most widely grown species in soilless conditions, in order to evaluate the depletion of nutrients together with productive and qualitative effects.…”

Soilless cultivation is one of the best examples of the sustainable intensification concept due to the high use efficiency of its inputs. Managing the nutrient solution through a closed cycle system represents a crucial objective to be pursued, but the recovery of the nutrient solution requires chemical correction and sanitization. The application of non-thermal plasma (NTP) in agriculture promotes the safety of the nutrient solution, decreasing the use of chemicals. The aim of this study was to evaluate the effects of cold plasma on the nutrient depletion, yield, and qualitative traits of lettuce. A closed soilless system (nutrient film technique) was used to compare different NTP treatments: control, low ionization (LI), and high ionization (HI) in two successive lettuce cycles. No significant differences within the nutrient depletion trends were observed. The treated lettuce’s yield was 12% higher than that of the control, characterized by a higher total soluble solid content and a significantly higher electrical conductivity and titratable acidity than the control. The ion content was higher in HI plants, as were the contents of nitrogen, phosphorous, and potassium. In HI plants, the leaf pigments were higher, but no significant changes were observed for the antioxidant content. Cold plasma is a promising strategy that brings benefits to the crop.

Effects of Nonthermal Plasma (NTP) on the Growth and Quality of Baby Leaf Lettuce (Lactuca sativa var. acephala Alef.) Cultivated in an Indoor Hydroponic Growing System

et al. 2022

The aim of this research was to develop an effective protocol for the application of nonthermal plasma (NTP) technology to the hydroponic nutrient solution, and to investigate its effects on the growth and quality of baby leaf lettuce (Lactuca sativa var. acephala Alef.) grown in a hydroponic growing system (HGS) specifically designed for indoor home cultivation. Four HGSs were placed in separate growth chambers with temperature of 24 ± 1 °C and relative humidity of 70 ± 5%). Lettuce plants were grown for nine days in nutrient solutions treated with NTP for 0 (control) to 120 s every hour. Results of the first experiments showed that the optimal operating time of NTP was 120 s h−1. Fresh leaf biomass was increased by the 60 and 120 s NTP treatments compared to the control. Treating the nutrient solution with NTP also resulted in greater leaf content of total chlorophylls, carotenoids, total phenols, and total antioxidant capacity. NTP also positively influenced chlorophyll a fluorescence in Photosystem I (PSI) and photosynthetic electron transport. These results revealed that the NTP treatment of the nutrient solution could improve the production and quality of hydroponically grown baby leaf lettuce.
