A plasma-nanobubble hybrid system was implemented for treating agricultural water.
The synergy between plasma electric discharge and hydrodynamic nanocavitation
can significantly increase yield in soilless cultivation.
The improvement of nutritional value of lettuce was observed in plants hydroponically
grown under optimal combination of two novel water processing technique.
Among new technologies aimed at improving water productivity, nanotechnology have been
identified as effective means of enhancing the properties of agricultural water. Building on the
synergy of plasma and nanobubbles, this study explored the combination of plasma
electric discharge and nanocavitation as a novel approach for soilless cultivation.
The study aimed to investigate the impact of this hybrid technology on hydroponics nutrient solution.
Additionally, the study further aimed to assess the effect of both technologies individually,
as well as various application periods, including 3, 9, and 15 min for hybrid technology use.
The study employed the nutrient flow technique to hydroponically cultivate lettuce.
The findings showed that the application of each technology individually did not significantly
increase yield. However, the hybrid technology treatment for 9 min resulted in a significant
yield increase of almost 60 %. This improvement can be attributed to the stability, solubility,
and absorption of products resulting from plasma treatment, as well as the antimicrobial
and anti-algae effects of both technologies. Additionally, an increase in flavonoid and potassium
content and a decrease in iron were observed in plants grown under optimal treatment.
Overall, this study demonstrated the potential for synergy between plasma and nanobubble
techniques in hydroponic culture.
