Non-thermal atmospheric gas plasma is popular for its flexibility and inexpensive cost. NTP is used in food preservation, medical therapy, biotechnology, and agriculture. This study examines how atmospheric plasma jets affect honeydew seed germination, water intake, and growth. In this research, high voltage (1.0–1.4 kV) was varied at a certain frequency with Argon gas. Honeydew melon seeds were a plasma treat sample. Untreated and treated seeds were separated at first. The seeds were examined for a few days after plasma treatment with varying voltage and exposure times. Wider pores reduce contact angle and promote wettability. Optical Contact Angle (OCA) measured the water droplet contact angle. Finally, plasma- treated seeds were compared to untreated seeds to determine plasma’s impact on seed quality.
