Recently, agricultural fields have used plasma technology for physical and/or chemical treatment. The two most important processes in the plantation are germination and early growth. There are two types of methods for using plasma to improve the germination and early growth process: plasma direct treatment of the seed and plasma activated water. There are two types of plantation methods in this study: hydroponic and in soil.
Such nutrients are provided to the treated seeds by the direct plasma treatment. By making the gibberellin (GA) hormone present on the seeds, the action of plasma species enhances germination. The results of using APPJ and CDA as the gas sources revealed that each type of seed is treated differently depending on its size and outer layer thickness. After plasma direct treatment, snap beans, kidney beans, garden peas, lettuce, and perilla leaf are displaying the best results.
In agriculture, PAW (plasma-activated water) is gaining popularity. PAW is regarded as a liquid fertilizer because it contains reactive oxygen-nitrogen species (RONS) like H2O2, NO2, and NO3. The RONS produced by plasma in the PAW may be quickly transported into plant cells, where they can function as nutrient sources or as signaling molecules in plant metabolism. Hydroponic systems are growing techniques that use nutrient solutions rather than soil substrates. APGDE and APPJ argon nitrogen as well as CDA are used in this study as the gas sources to create plasma activated water. Hydroponic systems have been used in conjunction with plasma direct treatment and plasma activated water. The most effective results were seen in perilla seeds, which also grew significantly after receiving a plasma treatment. Although lettuce also demonstrated this effect, the leaves are larger.
