Seed is the basic, vital and crucial input for crop production. Improved seed refers to a seed produced through a series of seed production channel that is suited for a particular domain, have a specific Package of practices, superior than local cultivars in many characters and offer farmer to harvest a bumper amount of crop through its genetics potential for bulk production. Improved seed is one of the ways to increase the productivity without adding appreciably to the extent of land. Improved seeds are free from diseases, have high vigor and germination capacity and have optimum moisture content. Good return per unit area, higher production, genetic potential, lesser pest, insect and disease problems, fast and uniform emergence, wider adaptability, highly input responsive are the properties that makes improved seed basic tool for sustainable agriculture. Various research findings have shown that there is about 20-25% increment in the yield through use of improved seeds only.
