Seeds are the most basic and vital input in agriculture. With the advent of green revolution, seeds form the backbone of modern agriculture contributing to 20% of yield improvement. Modern varieties and hybrids need strict production norms to maintain their genetic purity and vitality. This is ensured by adhering to quality checks during production, post production and distribution. Seed technology is a science that treats seeds as a living entity and ensures the quality and productivity of seeds. This course will enhance the knowledge of seed biology, seed quality, seed production, seed storage and seed certification. Starting with seed as a biological organism the course winds through its quality parameters, enumerates is production techniques, ensures is physical quality through processing, pervades quality checks through certification norms and finally reaches the farmer as a enhanced input ensuring assured returns. Seed production techniques of several important crops have been provided for the benefit of those who would like to venture into seed production. Even latest seed enhancement techniques like pelleting, priming and coating are provided for improved knowledge. On completion, one can possess sufficient knowledge on seed quality, its production strategy, processing methodology, distribution links and even legal issues.
