If Agriculture goes wrong, nothing else will have a chance to go right in the country. -M.S. Swaminathan. Seed is a material which is used for regeneration purpose. It has eminence as it is the cheapest input in crop production and a key to agriculture. Crop production and quality largely depend upon the seed materials used for sowing. The seed needs to be dried in a way that its germination and vigour should not be affected and make it available for next season crop.
