Germination Rate Calculator FAQ
What is a good germination rate?
Most commercial seed lots aim for 90% or higher germination under laboratory conditions.
Does germination equal field emergence?
No. Field emergence is often lower due to soil conditions, temperature, pests, and moisture variability.
Understanding Seed Germination Rate
Germination rate measures the percentage of seeds that successfully sprout under controlled conditions. It is a critical indicator of seed quality and planting success. Higher germination rates generally lead to stronger stands and more uniform crop establishment.
While laboratory germination percentages are often above 90%, actual field emergence can be lower due to soil temperature, moisture availability, compaction, and disease pressure. Understanding your seed’s germination rate helps adjust seeding rates to achieve target plant populations.
