Why is Thousand Seed Weight Important?

Thousand Seed Weight (TSW) is a crucial measure in seed quality assessment as it provides a standardized way to compare different seed lots. It helps farmers and agricultural professionals:

  • Understand seed size and quality
  • Calculate seeding rates accurately
  • Compare different seed varieties
  • Assess seed viability and purity

Example Calculation

If you have a seed sample weighing 25 grams that contains 500 seeds, the calculation would be:

TSW = (1000 × 25 g) / 500 = 50 g per 1000 seeds

This means each 1000 seeds in this sample weighs 50 grams.
