It is known fact that seed is a basic and crucial input in agriculture and it is the quality of seed that decides the commercial success of a crop variety. Obviously, the bumper harvest could be possible only when the seeds possess high quality standards viz., purity, germination, uniformity in weight and size apart from freedom from pest and diseases. These quality traits are known to be influenced largely by an interplay of environment, cultural, harvest and post-harvest management practices at both field and storage levels. Among these several factors, particularly maintenance of high quality seeds in storage is the most important aspect in many vegetable crops and particularly in onion which is a poor storer. Seed Coating Polymers are advanced seed coating polymers to provide protection against mechanical or environmental damage. It helps in application of fungicide treatments, seed colouring, and nutrient packages to promote better stand establishment. Seed Coating Polymer can be used in both as film coating and seed pelleting applications.
