The final version of the TN Corn Grain Hybrid Tests in TN publication is available as a pdf and excel files on search.utcrops.com. This report includes both the OVT and CST data.
Prelim results from the 2023 TN soybean OVT are now available as pdf (2023 Soybean Tables, 2023 Soybean Tables Appendix) and excel files (2023 Soybean Tables, 2023 Soybean Tables Appendix). Seventy-one varieties were evaluated in small plot replicated trials (REC) at 8 sites. In addition to yield, moisture, lodging, maturity, oil, and protein, data were collected on diseases, including frogeye and SDS, at locations where these diseases were present. The final CST data and disease trials are not in the prelim report but will be included in the final version to be posted here and on search.utcrops.com. Varieties that were in the A group in the OVT are listed below.
This year’s soybean CST class consist of 61 varieties covering late 3’s to early 5’s maturity groups. These trials are split by both maturity groups and herbicide tolerance, Late III, Early IV, Late IV, and Early V, and by Xtend and Enlist. These trials were planted on-farm across the state in 63 county demonstration plots.
If you have questions about UT’s variety testing program, please contact your local county agent.
Thanks to all who contribute to these trials and your support to the program.

39 Corn Hybrids were evaluated in the 2023 CST program. With the weather we had this summer, our yields are very strong with an overall average across all hybrids and locations over 210 bu/ac. With the many locations/replications in these trials, we can look at performance across many soil types and weather/climate conditions that you can use to help select high yielding, consistent hybrids to bring to your farm. Contact your local county agent for more details or if you need a print out of this data.
These CST plots are large strip trials located ‘on-farm’ with a minimum of 300 feet in length. Inputs and management decisions are on a by location basis and determined by the cooperating producers. Three relative maturity groups divide the trials, Early Corn will be 113 day and earlier, Medium Corn will be 114-116 day, and Full Corn is 117 day plus. Thank you to everyone involved in the CST program for your support and contributions: County Agents, UT Extension/Research, Growers, Industry, Retail.

Prelim results from the 2023 TN corn grain hybrid OVT are now available as an excel file 2023 Corn Grain Tables. Thirty-three hybrids were evaluated in small plot replicated trials (REC) at 9 sites. The CST trial data is still being finalized but should be posted within the next week and will be included in the final combined report to be posted here and on search.utcrops.com.
While we’ve been steadily moving through harvesting our trials, I’ve been paying close attention to the night temperatures forecast for the three day stretch centered on Halloween. Fortunately, there are only a few acres left that might require any more boll opener; I cannot recall a more productive year harvested in such a short timeframe. Still, for those trying to prepare their latest planted acres for the picker, the time to make that final application of boll opener is NOW. In this article, I briefly cover rates and products I would consider for applications going out today (10/25) or tomorrow (10/26).
Last year we reported on waterhemp in Montgomery and Macon counties that was resistant to dicamba. We came to this conclusion from both research we conducted in the fields and the confirmation of those results by greenhouse research. The greenhouse research was conducted at Purdue University by my colleague Dr. Bill Johnson and his graduate student Claudia Bland. Continue reading
Ryegrass has become a serous weed issue in some fields that past couple of years. A major reason for this is that much of it is now glyphosate-resistant. Even if clethodim is used rather than glyphosate often it is applied on ryegrass sometime in late March through April when the grass is too well established to provide consistent control.
