Nanobiostimulants for Enhancing Plant Stress Tolerance

Nanobiostimulants, comprising nanoparticles and biostimulants, represent an emerging and promising domain within agricultural science. The integration of these specialized nanomaterials into agricultural practices aims to boost crop productivity while concurrently moderating the adverse impact of environmental stresses on plant life. The current use of chemical fertilizers poses significant risks to human health and ecological networks, making the application of nanobiostimulants a compelling alternative. These stimulants demonstrate the potential of strengthening plant growth along with enhanced nutritional value, improving productivity, prolonging shelf-life, and reinforcing plants against biotic and abiotic stressors. Despite their potential, the widespread adoption of nanobiostimulants faces challenges. The lack of comprehensive knowledge regarding the complex interrelationship between biostimulants, nanoparticles, and plant biology hampers their broad recognition and utilization in agricultural sector. Addressing this gap necessitates extensive research and exploration to formulate more suitable and commercially viable nanobiostimulants for the global farming community. This book chapter highlights the role of nanobiostimulants in addressing the challenges caused by both abiotic and biotic stresses in plants. The assessment underscores the critical importance of optimizing the synergistic interaction between nanoparticles and biostimulants to ensure efficient delivery and release at the specifically targeted sites, thereby creating effective and precise nanobiostimulants. The development of more sophisticated and practical nanobiostimulants is a pressing need, requiring the application of state-of-the-art methodologies to comprehend the multifaceted factors that drive agricultural success.
