EHT power systems can produce nonthermal plasma (NTP) for the agricultural sector. NPTs are an eco-friendly alternative to conventional agrochemical treatments used in pre- and post-harvest. They can remove pesticides and contaminants from the seed surface, increase the shelf life of crops, improve germination, and enhance resistance to abiotic stress. Pre-treatment of seeds and seedlings with non-thermal plasma can stimulate germination, growth, and alleviate stress. Moreover, plasma-activated water (PAW), a product of NTP, has been highlighted for its role in seed germination, plant growth, stress tolerance, and antibacterial ability. The application of NTP in agriculture is still in its early stages but is rapidly increasing. It holds great promise for sustainable and efficient agricultural practices in the future.
