Enter the seeds germinated and the total seeds planted into the Calculator. The calculator will evaluate the Percent Germination. 

Percent Germination Formula

PG = SG / TS * 100

Variables:

  • PG is the Percent Germination (%)
  • SG is the seeds germinated
  • TS is the total seeds planted

To calculate Percent Germination, divide the number of seeds germinated by the total seeds planted, then multiply by 100.

How to Calculate Percent Germination?

The following steps outline how to calculate the Percent Germination.

  1. First, determine the seeds germinated. 
  2. Next, determine the total seeds planted. 
  3. Next, gather the formula from above = PG = SG / TS * 100.
  4. Finally, calculate the Percent Germination.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

seeds germinated = 600

total seeds planted = 300

FAQs

What factors can affect seed germination rates?

Several factors can affect seed germination rates, including temperature, moisture, soil quality, and light exposure. Seeds may require specific conditions to break dormancy and start germinating.

How can I improve the germination rate of seeds?

To improve germination rates, ensure seeds are planted in suitable soil, maintain optimal moisture and temperature levels, and follow any specific pre-treatment procedures such as soaking or stratification if required by the seed type.

Why is it important to calculate the percent germination of seeds?

Calculating the percent germination is crucial for understanding seed viability and overall quality. It helps in planning the quantity of seeds needed for a certain area and in assessing the potential success of the crop.

Can the percent germination formula be used for any type of seed?

Yes, the percent germination formula (PG = SG / TS * 100) is universal and can be applied to any type of seed to calculate its germination rate, as long as you have the necessary data for seeds germinated and total seeds planted.
