West RIver Seed started as an idea to source and supply the highest quality seed genetics that specifically fit the Dakotas. While most other seed brands view their product decisions through a national lens, West River Seed takes a local approach to seed genetic selection. Through extensive local testing, West River Seed finds the genetic lines and hybrids that are most suited for the tough conditions of farming in the Dakotas.


Things work differently out here, and you can be assured that West River Seed only sources products that are proven to work right here.
