Growth of Hydroponic Sweet Basil (O. basilicum L.) Using Plasma-Activated Nutrient Solution (PANS)

Hydroponic sweet basil (O. basilicum L.) farming uses a recirculating nutrient solution that may spread waterborne microbial contamination including algae. Plasma, the fourth state of matter, generates antimicrobial reactive oxygen and nitrogen species when exposed to water. The objective this work was study effect plasma-treated water-based on plant growth in reduction Basil plants were grown isolated ebb flow hydroponic systems (under monitored environmental conditions) using (NS) plasma-activated (PANS) with two separate treatments: same irrigation solutions used cycle (Treatment 1: NST1 PANST1 once at beginning cycle) new every week 2: NST2 PANST2). parameters (height, fresh dry weight, number branches nodes, root length, leaf index), quality (color, texture, aroma, tissue nutrients concentration), algae concentrations measured. Compared NST1, significantly taller (up 12%), had higher mass 29%) 45%), greenness value 28%). Algae reduced PANST2 reservoir 24%) compared reservoir. It confirmed Treatment 1 improved yield, morphology, plants, while 2 best suited decreasing concentration environment. This preliminary indicated PANS could improve controlling growing
