Consequently, the expected benefits of supplying “improved seed” have not always been achieved in practice. The endosperm is a source of stored food, consisting primarily of starches. SEED helps seismologists who record, share, and use seismological data. <> The quality seed respond well to the applied fertilizers and nutrients. Stir the drying seed 4 to 5 times per day to ensure that the seed is thoroughly dry. Seed moisture is the most important factor affecting seed longevity.

In any seed lot, losses of seed vigour are related to a reduction in the ability of seeds to carry out all the physiological functions that allow Each seed is constructed and packaged to ensure its dispersal to a favorable site for successful germination and growth.
