Seed is botanically defined as a matured ovule containing an embryo in an arrested state of development with food reserved in endosperm/ cotyledons surrounded by seed coat which is protective layer. In due respect to all agricultural inputs, seed is the most significant for two reasons. First, it is the propagule carrying unique genetics that culminate in optimum crop response to varying environments. Second, seed is the reproductive unit responsible for ensuring successful stand establishment for most agricultural crops (McDonald, 2003). There are many factors that can narrow down the gap between potential and farm level yield. Among them, use of quality seed is the most important one (Ahmad, 2001), as quality seeds ensure better germination as well as better yield. But if the seed is inferior quality crop failure is unavoidable. To the farmers for satisfactory crop production, a high quality seed is not only desirable but also satisfactory required. Although seed quality is governed by genetic make-up, commonly the quality of seeds may deteriorate in subsequent stages like harvesting, threshing, processing and storage period. Retention of seed germination always forms the important consideration in agricultural practices. Poor seed handling condition gives rise to deterioration of seed quality and the resultant loss of viability. Also this greatly affects seed vigor, as a result the quality of the seed becomes bad and the seed is unusable for crop production. Hence, some physical and chemical operations are performed with the seeds between the processing to storage time to overcome these problems.
