Zomorodian 2 1 Armenian National Agrarian University, Yerevan, Armenia 2 AgroTechnik International, Yerevan, Armenia Abstract: The escalating global demand for food necessitates a paradigm shift in nitrogen fixation methods to ensure both food security and environmental sustainability. This study explores the transformative potential of cold plasma technology and nano-fertilizers as sustainable alternatives to the energy-intensive and environmentally detrimental Haber-Bosch process. Cold plasma, with its unique ability to facilitate chemical reactions under mild conditions, presents an intriguing avenue for on-farm, energy- efficient nitrogen fixation. The intricacies of different plasma types and their impact on nitrogen conversion are examined, emphasizing the pivotal role of digital control in achieving consistent and optimized performance. Precision tuning of plasma parameters, including power, frequency, and gas flow, is highlighted as essential for efficient nitrogen fixation and minimal byproduct generation. Nano-fertilizers, engineered on the nanoscale, revolutionize nutrient delivery by enhancing plant uptake and minimizing environmental impact. Their potential to indirectly influence nitrogen availability by promoting nutrient utilization and reducing overall fertilizer needs is explored. A comparative analysis of traditional and sustainable nitrogen fixation methods underscores the environmental benefits offered by cold plasma and nano- fertilizers, including lower energy consumption, compatibility with renewable energy sources, and reduced greenhouse gas emissions. The manuscript concludes by stressing the convergence of cold plasma and nano-fertilizers as a potent force for ushering in a green revolution. Continued research and development are highlighted as crucial for unlocking their full potential, paving the way for a future where food security and environmental responsibility seamlessly coexist.

Introduction: Nitrogen, the cornerstone of life, plays a critical role in plant growth and development. It fuels protein synthesis, chlorophyll production, and numerous other vital cellular processes [1, 4]. In agriculture, nitrogen fixation bridges the gap between atmospheric nitrogen and forms readily usable by plants, serving as the linchpin of food production [2, 3]. The Haber-Bosch process, a revolutionary innovation of the 20th century, enabled large-scale nitrogen fixation, dramatically boosting agricultural yields [5, 6]. However, its energy-intensive nature and significant greenhouse gas emissions raise concerns about environmental sustainability [7, 8].
