Comparison of nutrient use efficiency, antioxidant assay, and nutritional quality of butter-head lettuce (Lactuca sativa L.) in five cultivation systems

A greenhouse experiment was conducted to evaluate the comparison of nutrient use efficiency, antioxidant assay, and nutritional quality butter-head lettuce in five cultivation systems. For this experimental study, a split-boxes arrangement completely randomized design (CRD) with three aeroponics systems (high pressure (T1), low (T2), ultrasonic nozzle (T3)), hydroponic system (T4), conventional (T5) designed. The analyses variance (ANOVA) were employed assess yield, chlorophyll content, relative water content (RWC), efficiency (NUE), 2,2-Diphenyl-1-picrylhydrazyl (DDPH), Hydrogen Peroxide (H2O2), Ferric Reducing Antioxidant Power (FRAP), total phenolic (TPC), flavonoid (TFC) lettuce. comparative results indicated that shoot root (fresh dry) weight, root-to-shoot ratio, contents, CWC, NUE, DDPH, H2O2, FRAP, TPC, TFC, nitrate, vitamin C, protein level significantly (p 0.7) among Shoot (FW), Chlorophyll, RWC, FRAP. This study demonstrates grown high-pressure nozzles may serve as potential dietary source is rich natural antioxidants.
