What to enter
| Input | Meaning and units |
|---|---|
| Seeds tested (seeds) | Enter seeds tested in seeds; use the same basis as the other measurements. |
| Seeds germinated (seeds) | Enter seeds germinated in seeds; use the same basis as the other measurements. |
Understanding your result
This summarizes the tested sample and does not guarantee a future seedling count.
Common mistakes
- Count each germinated seed once and use the tested count as denominator.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.

What percentage of the seeds in my test germinated?
Summarize an observed seed test as germinated percentage and ungerminated seed count.
Common uses
- What percentage of the seeds in my test germinated
How it works
Divide the observed germinated count by tested seeds and multiply by 100. This summarizes the tested sample and does not guarantee a future seedling count. Measured quantities and user-selected spacing only; no crop, watering, chemical treatment or growing recommendation is provided. Biological outcomes can differ.
Worked example
Enter Seeds tested: 50 seeds; Seeds germinated: 42 seeds. Results: Observed germination: 84 %; Seeds not germinated: 8 seeds.
