Plants of the other group, the gym- nosperms, the "naked seed" plants, have no ovaries, no flowers, and no fruits, although they do have seeds. this maize seed production technique manual is to improve the knowledge to farmers about technical and management activities, including increment in production of quality seed of Different types of the same species exist due to this adaptive nature. SEED PROCESSING. Hence, production of certified seed has resulted in a win-win situation for the farmers with higher yield and increased returns. Food grains production has risen from 50 million tons in 1947 to 212 million tons in 2003-04. First global estimate of importance of pollinators for seed production in plants About 175 000 plant species -- half of all flowering plants -- mostly or completely rely on animal pollinators to . Seed plays a key role in increasing food and fibre production to meet the increasing demands of the people, and is a focus around which strategies to boost crop yields can be built.
