Weeds are hard enough to combat without planting them with the seed. This is usually the least expensive in terms of direct cash outlay but can be burdened with many problems. If the answer is yes, then there are other questions to satisfy. Obviously, if the answer to the first question is no, it is time to look for other sources of seed to plant. There are many ways for seed to lose its varietal purity.
Mixtures can occur in the drill, the combine, or the storage bin.
The second consideration relates to the physical purity of the seed. Once seed purity has been satisfied, question the ability of the seed to germinate. Poor germination can be caused by combine damage, harvesting at too high a moisture content, storage problems, sprouting in the head, or seed dormancy. Seed should be sent to a seed testing laboratory for a germination test required on any seed sold in Nebraska. Wheat that has passed all these tests is probably a likely candidate for planting as a seed substitute.
