There is always a temptation with small grains to purchase certified seed every few years and save seed from the initial crop for replanting. This results in a cost saving on the average annual expense of seed, but may lead to seed purity issues, reduced yields and less profit per acre.
There are good reasons Michigan State University Extension recommends to consider planting certified seed every year.
In addition, one of the advantages of planting certified seed is that you can be relatively assured that the seed is professionally treated. Sometimes seed treatment done on the farm is not adequate.
A Kansas study from the 1990s, “Economic Issues with Certified and Farmer-Saved Wheat Seed,” addresses the economic benefits to Kansas wheat farmers of using certified seed, particularly those selling to identity-preserved systems, where millers want specific varieties. Basic concepts from the study can be applied in current Michigan systems.
