  1. Wheat Growth Stages and Associated Management- Feekes 6.0 through 9.0

    Author(s): Laura Lindsey , Author(s): Pierce Paul , Author(s): Ed Lentz, CCA

    With below average temperatures and snow, wheat growth and development is slower this year compared to the previous two years. Last year, wheat in Pickaway County reached Feekes 6.0 growth stage the last week of March. Remember, exact growth stages cannot be determined by just looking at the height of the crop or based on calendar dates. Correct growth identification and knowledge of factors that affect grain yield can enhance management decisions, avoiding damage to the crop and unwarranted or ineffective applications.

  2. Winter Wheat Stand Evaluation

    Author(s): Laura Lindsey , Author(s): Ed Lentz, CCA

    Feekes 5 growth stage (leaf sheaths strongly erect) is a good time to evaluate winter wheat stand. Over the past two years, with funding from the Ohio Small Grains Marketing Program, we evaluated the relationship between wheat stems (main stem + tillers) and yield.

    Keep in Mind:

    In our research, we counted the number of wheat stems which included both the main stem (main plant) and tillers. For example, in Figure 1, there are two stems.

    Make sure to count the number of stems in several areas of the field.

  3. Small Grains Field Day

    Author(s): Rory Lewandowski, CCA

    The OARDC Schaffter Farm located at 3240 Oil City Rd., Wooster, will be the host location for the 2017 Small Grains Field Day scheduled for Tuesday, June 13.  Registration is now being accepted for the event which runs from 9:30 am and concluding around 3:15 pm.   In addition to looking at how small grains are used as a grain crop the field day will also provide information and demonstrations about wheat quality and use in food products, small grains as cover crops, alternative forages, and how small grains fit into row cropping systems.   Participants will have the opportunity to walk thro

  4. Frost Damage in Wheat

    Author(s): Laura Lindsey , Author(s): Douglas Alt , Author(s): Pierce Paul

    Air temperatures dropped to an average of about 25-32 degrees on at least two nights over the last few days. Understandably, some wheat producers are concerned that these temperatures may have caused some damage to their crop. We will have to see what happens over the next few days.

  7. Winter Wheat Progress and Management- Check Your Fields

    Author(s): Laura Lindsey , Author(s): Pierce Paul , Author(s): Ed Lentz, CCA

    Last year, wheat winter progressed quicker than usual due to warm temperatures. In our Pickaway County trials in 2016, wheat reached Feekes growth stage 6.0 by April 6. This year, with unusually warm temperatures, we may see something similar. Don’t rely on calendar date. Check your fields for growth stage.

  8. Purple Wheat

    Are you seeing purple wheat?

    Author(s): Laura Lindsey , Author(s): Alexander Lindsey , Author(s): Ed Lentz, CCA , Author(s): Pierce Paul , Author(s): Steve Culman , Author(s): Eric Richer, CCA

    Some farmers in northwest Ohio have noted purple-reddish leaves on their wheat crop (see picture). If your wheat plants turned purple, here are a couple of things to note:

  10. Assessing the Wheat Crop for Freeze Damage

    Author(s): Laura Lindsey , Author(s): Douglas Alt , Author(s): Pierce Paul

    Over the weekend, temperatures dipped to high 20s/low 30s sometimes accompanied by a frost.  The extent of damage to the wheat crop depends on the growth stage, temperature, and duration of the low temperature.  Wheat is most sensitive to freezing temperatures at the heading and flowering stage.  At heading and flowering, two hours at 30°F can result in severe yield loss due to sterility.  Flowering begins near the center of the wheat spike (Feekes 10.5.1) followed by the top (Feekes 10.5.2), and bottom (Feekes 10.5.3) of the spike.  Depending on the flowering stage, sterility may only occu
