The intensifying need for sustainable agricultural practices has driven significant interest in eco-friendly seed enhancement techniques. Among these, seed coating is a method to enhance seed viability and protection has benefited from the incorporation of biodegradable nanomaterials. Biodegradable nanomaterials represent a sustainable alternative to synthetic coatings due to their ability to deliver nutrients precisely, enhance stress resistance, and safeguard beneficial soil microbiota. This study explores the latest advances in biodegradable nanomaterials used in seed coating, focusing on natural polymers such as polysaccharides, proteins, and polymers. The functional mechanisms by which biodegradable nanomaterials improve seed performance are critically analyzed. These materials impact seed germination, root development, and stress resistance by modulating water retention, nutrient bioavailability, and plant–microbe interactions. The influence of nanomaterial properties such as particle size, surface area, surface charge, and biodegradation rates on plant physiological responses is also examined. By enhancing both biotic and abiotic stress tolerance, these nanomaterials enable more uniform germination and early seedling establishment under diverse conditions. The integration of bioactive agents and micronutrients into multifunctional coatings demonstrates significant potential to address both biotic and abiotic challenges in agriculture. Laboratory-scale studies have shown promise; however, extensive field trials are essential for validating these innovations across varied agricultural systems. The role of biodegradable nanomaterials is pivotal in enhancing crop productivity while aligning with global sustainability goals.
