Explanation:

Seed Replacement Rate (SSR) or Seed Replacement Ratio is a measure of how much of the total cropped area was sown with certified seeds in comparison to farm saved seeds. However, since every farmer is aware of the benefits of certified seeds; he would want to sow certified seeds, provided he is supplied with required quantity of certified seeds. Thus,Seed Replacement Ratio also denotes actual quality seed distributed to farmers vis-a-vis actual seed required for cultivation of crops.
Since certified seeds are better in productivity, the Seed Replacement Rate is directly proportional to productivity. Thus, higher the Seed Replacement Ratio, higher is production as well as productivity and higher are chances of achieving nutritional security, food security and containing food price inflation.
