Is Spring Wheat an Option for Ohio Farmers?

Is spring wheat an option for Ohio farmers? Yes, we can grow spring wheat in Ohio, but spring wheat yield will be significantly lower than winter wheat yield.

Last year, in collaboration with University of Wisconsin-Madison, we participated in a small grain resiliency field trial located at the Northwest Agricultural Research Station in Wood County. The goal was to compare several types of small grains to our local standard of soft red winter wheat. Results are shown in Figure 1. On average, soft red winter wheat yielded 97 bu/acre across eight different varieties. As a comparison, durum (planted in the spring) yielded an average of 44 bu/acre and hard red spring wheat yielded an average of 52 bu/acre. The data below represents one year of data; however, similar observations have been made in previous trials conducted in Ohio.

In small grains, the grain fill period begins at Feekes 10.5.4 (kernels watery ripe) and ends at Feekes 11.3 (kernels hard, but dividable with thumbnail). Longer grain fill periods are associated with higher yields. For all four winter wheats (soft red, soft white, hard red, and hard white), the grain fill period was between June 3 and June 30, for a total of 27 days long (Figure 2). However, the grain fill period was only 13 days for the hard red spring wheat (between June 17-June 30) and only 8 days (between June 22 and June 30) for the durum wheat. Although, our winter wheat was planted on September 25, 2021 and the spring wheat was planted on April 5, 2021, all wheat reached maturity at the same time and were harvested on the same date. Thus, the higher yield of winter wheat is likely due in part to the longer grain fill period.

In addition to yield, there are other factors to consider:

  1. Do you have a place to sell spring wheat? Is there a market for spring wheat?
  2. Can you meet grain quality requirements? Soft red winter wheat and white wheat tend to have low protein (8.5 to 10.5%). Hard red winter wheat has medium to high protein (10.0 to 13.0%) while durum and hard red spring wheat have high protein (10 to 15.0%). For more information on the various wheat classes and requirements, see: https://www.uswheat.org/working-with-buyers/wheat-classes/

Although wheat prices are high, spring wheat is probably not the best option in 2022 due to low yields and uncertainty surrounding selling the grain and quality. However, we will continue to look at these various wheat classes this year as opportunities may arise in the state. If interested in wheat, the best option would be to plant soybean this year followed by winter wheat planting in the fall.
