Plasma technology for enhanced seed viability, germination, and pathogen elimination

Overview

This solution leverages plasma technology to address critical challenges in crop production, including climate change, environmental hazards, and shrinking agricultural land. By treating seeds with carefully controlled plasma, the technology delivers specific reactive species, densities, and temperatures to stimulate biological processes that enhance seed viability, germination, growth, and pathogen elimination. The approach offers a promising alternative to traditional methods for ensuring higher crop yields and disease-free seeds, supporting growers and farmers in meeting food and horticultural demand.

Technical specifications

• Uses low-pressure dielectric barrier discharge plasma for seed treatment
• Treatment parameters include varying plasma species connected to a high voltage power supply of 1–6 kV at a frequency of 3–5 kHz
• Controls reactive species, species densities, temperatures, and treatment time to stimulate beneficial biological processes
• Targets three key outcomes: enhanced seed viability, improved germination and growth, and pathogen elimination
• Validated on wheat, black gram, and rapeseed with demonstrated improvements in germination and growth
• Future validation will include tomato and spinach seeds
• Wet-lab analysis encompasses physiological, agronomic, and molecular characterization to optimize best treatment conditions and understand underlying mechanisms
• Testing planned in both growth chamber and field trial settings to confirm results

Technology readiness level

The technology has demonstrated proof-of-concept through successful validation on wheat, black gram, and rapeseed seeds using low-pressure dielectric barrier discharge plasma. Future work will expand testing to tomato and spinach seeds, incorporating systematic optimization of plasma parameters and comprehensive mechanistic characterization. Both controlled environment (growth chamber) and field trials are planned to validate the technology under real-world agricultural conditions before broader deployment.
