Non-Thermal Plasma and Soilless Nutrient Solution Application: Effects on Nutrient Film Technique Lettuce Cultivation

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