The extensive use of chemical fertilizers to increase crop yields in agricultural fields has had a negative impact on the environment. To produce more food less land and fulfill growing global demand for food, farmers will need innovative environmentally friendly technology. Several studies have cited positive effects plasma-activated water (PAW) seeds their research findings. This study investigates PAW four distinct seed species: phapar (Fagopyrum esculentum), barley (Hordeum vulgare), mustard (Brassica nigra), rayo juncea). Deionized (DI) was treated 5 or 10 min using gliding arc discharge (GAD) system, which operated by line frequency air. Water analysis indicates that physiochemical parameters (electrical conductivity, pH, nitrate, nitrite, ammonia concentration) were significantly different from DI water. Despite exposure GAD certain period time, temperature did not alter significantly. All calculated germination enhanced with compared control. In addition, they displayed significant total seedling length exhibited greater vigor. Seeds immersed absorbed than soaked water, enabling rapid penetration into early emergence. puts plasma agriculture ahead conventional farming methods.

Water-related crisis represents one of the significant challenges rapidly growing world population. This study demonstrates an example novel technology Non-Thermal Plasma (NTP) wastewater treatment for its sustainable recovery and reuse in agriculture. NTP not only causes microbial decontamination but produces Reactive Oxygen Nitrogen Species (RONS), which can consequently improve seed germination plant growth. We focused on effects new Fountain Dielectric Barrier Discharge air plasma reactor bulk quantity water contaminated by Staphylococcus epidermidis or Escherichia coli bacteria. Then, using treated barley shows >20% enhancement compared to tap water. The inactivation bacteria was determined dependence pH, Oxidation-Reduction Potential, correlated with chemical RONS produced (hydrogen peroxide, nitrites, especially nitrates). By utilizing Responses Surface Methodology, we identified optimal time per litre required efficient production bactericidal effect treatment, linearly scalable volume.
