How to ensure seed quality

good and poor seedsGood quality seeds (left) are uniform in size, full, and plump; while poor quality seeds (right) are often discolored.Seed is the foundation of any rice crop. It must be grown, harvested, and processed correctly for best yield and quality results.

Sowing good quality seeds leads to lower seed rate, better emergence (>70%), more uniformity, less replanting, and vigorous early growth which helps to increase resistance to insects and diseases, and decrease weeds. As a result, yield can increase by 5−20%.

While different countries have different standards for seed quality the following factors are used to classify rice seeds:

How to obtain good seed

  • Buy certified seed that is pure and labeled
  • Get farmer-produced good seed, or
  • Select your own good seed

High quality seeds are free from weed seeds, seed-borne diseases, insects, pathogens, and other extraneous matter. They should also be free from various types of mechanical injury that reduce germination and seedling vigor.

In case of infected or low quality seeds, treatments can be done.
