Factor Protein into Spring

Wheat Variety Performance

AgriPro Wheat spring wheat breeder Joe Smith believes that protein premiums (or discounts) should be factored into income potential when selecting varieties. Smith compares the three-year performance of leading private and public spring wheat varieties by economic return in the following table, using the 10-year average premium for wheat protein at Minneapolis and a Sept. local cash grain price of $3.47 for 14% protein.
