If the pure seed content is 90% and the germination rate is 90%, what is the percent Pure Live Seed (PLS)?

To find the percent Pure Live Seed (PLS), you multiply the pure seed content by the germination rate. In this case, the pure seed content is 90%, which indicates that 90% of the seed is actually the desired species. The germination rate is also 90%, meaning that 90% of the seeds that are pure will successfully germinate.

The calculation for PLS is as follows:

[ \text{PLS} = \text{Pure Seed Content} \times \text{Germination Rate} ]

Converting percentages to decimals for calculation:

[ \text{PLS} = 0.90 \times 0.90 = 0.81 ]

Then converting back to a percentage:

[ 0.81 \times 100 = 81% ]

This means that 81% of the total seed lot consists of pure seeds that will successfully germinate. The 81% indicates a healthy and viable seed lot that can be used in planting. Hence, the answer is 81%. This calculation is essential for growers to understand the true value and effectiveness of the seed being planted.
