Field emergence
It is the percentage of planted seeds that successfully produce seedlings under actual field conditions, reflecting the combined impact of seed quality and environment.

Field emergence is a critical agronomic metric that serves as a reality check for lab germination tests. It accounts for environmental stressors such as soil crusting, cold temperatures, and moisture availability, providing a realistic estimate of the final stand density.
Farmers use this data to determine optimal seeding rates. If field emergence is expected to be low due to poor soil conditions, the sowing rate is typically increased to compensate. Common mistakes include seeding too deep or too shallow, as well as planting into soil with insufficient seed-to-soil contact, which leads to uneven germination.
