What to enter
| Input | Meaning and units |
|---|---|
| Expected seedling target (seedlings) | Enter expected seedling target in seedlings; use the same basis as the other measurements. |
| Entered germination rate (%) | Enter percentage units: 5 means 5%, not a fraction of 0.05. |
Understanding your result
Expected value only, not a confidence bound or a guarantee; later losses are excluded.
Common mistakes
- An 80% germination rate requires division by 0.8, not adding 20% to the target.
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.

How many seeds correspond to my target at an entered germination rate?
Estimate a seed quantity for an expected seedling target using a supplied germination percentage.
Common uses
- How many seeds correspond to my target at an entered germination rate
How it works
Divide the target by the entered germination fraction and round seeds upward. Expected value only, not a confidence bound or a guarantee; later losses are excluded. Measured quantities and user-selected spacing only; no crop, watering, chemical treatment or growing recommendation is provided. Biological outcomes can differ.
Worked example
Enter Expected seedling target: 100 seedlings; Entered germination rate: 80 %. Results: Estimated seeds to sow: 125 seeds; Expected germinated count: 100 seedlings.
