Seed treatment is a strategic pre-sowing intervention designed to enhance crop establishment under diverse biotic and abiotic stress conditions by improving germination, seed vigor and early-stage protection. Chemical, biological and physical seed enhancement techniques including priming, coating and dressing are evaluated using standard seed quality parameters such as germination percentage and seedling vigor index. These treatments have been shown to improve germination by 10-25 per cent and contribute to yield gains ranging from 5-15 per cent, depending on crop and environment. By increasing input-use efficiency and strengthening stress tolerance, seed treatment plays a critical role in climate-resilient agriculture and sustainable crop intensification.
