Abstract
Nano-seed coating technologies have emerged as a revolutionary tool in modern agriculture, offering promising solutions to enhance vegetable seed performance and stress tolerance. These coatings integrate nanomaterials with bioactive compounds, enabling precise delivery of nutrients, growth regulators, and protective agents directly to the seed. The nanoscale size ensures improved adhesion, controlled release, and enhanced interaction with the seed surface, fostering uniform germination and seedling vigour. The application of nano-coatings not only improves the physiological quality of seeds but also enhances their resilience to abiotic stresses such as drought, salinity, and temperature extremes. Encapsulation of essential nutrients and biostimulants within nanocarriers boosts seed metabolic activities, while antimicrobial and antifungal agents in the coating provide protection against seed-borne pathogens. Additionally, the technology supports sustainable agricultural practices by reducing the need for excessive agrochemical use. Recent advancements have demonstrated significant improvements in germination rates, root development, and overall plant growth in various vegetable crops, making nano-seed coatings a pivotal innovation for food security in stress-prone environments. Future research should focus on optimizing formulations, evaluating environmental safety, and scaling up production for widespread adoption, bridging the gap between nanotechnology and resilient agricultural systems.
