Results are now available for the TN corn hybrid official variety trial (OVT). These small-plot, replicated trials were conducted at 8 sites across 6 UT AgResearch and Education Center locations (Jackson, Milan, Spring Hill, Springfield, Knoxville, & Greeneville). This year’s trial included 31 hybrids total. These were broken into three separate trials based on maturity, including 11 early (<114 DAP), 9 medium (114 – 116 DAP), and 11 full (>116 DAP). The final report will be posted once all county CST trial data is in and analyzed. For prelim tables with OVT results only, click here –  2026 Corn Grain Tables Prelim – OVT only

Finding a cover crop variety that is adapted to both your region and growing system is critical to maximizing benefits like weed suppression, nitrogen credits, and more. This past year,  we evaluated 21 cover crop varieties across 6 states (AL, KY, FL, GA, LA, & TN). Preliminary data tables showing how these varieties performed both early season and at termination can be found here 25-26 Southern Cover Crop Variety Trial Tables – Prelim.

An issue was found that caused an error when importing variety names in the previously published final version of the soybean report. This has been corrected and updated in the previous post. If you already downloaded the files from 11/25, please discard and used the updated versions below.

Our 2025 TN Corn Official Variety Trial (OVT) results are now available. These data are from our small plot trials performed at eight sites located within six of our UT AgResearch and Education Centers across the state (Jackson, Milan, Spring Hill, Springfield, Knoxville, and Greeneville).

This year, we had 40 hybrids, representing 11 brands/companies, included in the OVT. Our top performers (those not statistically different from the highest yielding hybrid within each test) are listed in the 2025 OVT Corn “A Group” Table below. The full results, including information on yield, moisture, test weight, plant and ear height, lodging, protein, oil, and starch for each hybrid within and across locations is available as an excel file download – Corn Grain Tables 2025 PRELIM – OVT ONLY.

County trial data is not included in this PRELIM report as that data is still coming in. It will be included in the FINAL report.  Continue reading →

Summer crop harvests are right around the corner and it’s time to start planning for winter cover crops. Cover crops offer numerous benefits, but maximizing those benefits starts with selecting species and varieties that are well suited to your region and system.

The Southern Cover Crop Variety Trial is here to help you do that. Our 2025 results are now available as a pdf or excel file, with archives of previous year’s trials available on search.utcrops.com/cover-crops. This year’s trial included 20 varieties (4 brassica, 8 cereal, and 8 legume) and 8 sites across 7 states (AL, FL, GA, KY, SC, TN, and LA).

Results from the 2024 Tennessee OVT, CST, and Disease soybean trials are now available (full report pdf, excel tables, excel appendix tables). The summary sheet below (Table 4 in the full report) lists varieties in the “A Group” (not statistically different from the highest yielding variety) in either one or both of the REC and CST trials. Listed for each variety are yield, number of years that variety has been in the A group and the percent of locations where that variety had above average yield (click the image to view larger size).

AgResearch and Education Center (REC): Eighty soybean varieties were evaluated at nine sites in small plot replicated trials . There were 8 varieties in MG3, 24 in MG4E , 40 in MG4L, and 8 in MG5 tests. Herbicide tolerance varied by entries with the majority falling into the XtendFlex (XF) or Enlist E3 categories, either with or without STS tolerance (61 entries).

County Standard Tests (CST): Forty-nine soybean varieties were evaluated in unreplicated strip trials. Trials included MG3 / MG4E XF (9 varieties at 5 locations), MG4E Enlist ( 26 varieties at 7 locations), and MG4L XF (14 varieties at 7 locations).

Disease Trials: County trials at three AgResearch and Education Center sites were evaluated for yield with and without a fungicide application. Yield as well as ratings for frogeye, target spot, brown spot, and soybean cyst nematode are reported.

Results from the 2024 Tennessee OVT and CST trials are now available in pdf or excel format. Tests were grouped by maturity into early (<114 DAP), medium (114 – 116 DAP), and full (> 116 DAP). Data were collected on yield, moisture, test weight, lodging, height, protein, oil, starch, and disease.

AgResearch and Education Center (REC): Forty corn hybrids were evaluated at nine sites in small plot replicated trials . There were 10 hybrids in the early- (Tables 4-5), 21 hybrids in the medium- (Tables 9-10), and 9 hybrids in the full-season (Tables 14-15) tests.

County Standard Tests (CST): Twenty-seven corn hybrids were evaluated in unreplicated strip trials. Trials consisted of an early- (11 hybrids at 9 locations, Table 6), a medium- (8 hybrids at 15 locations, Table 11), and full-season test (8 hybrids at 14 locations, Table 16).

Common to both the REC and CS tests were 5 early-season, 7 medium-season, and 3 full-season hybrids (Tables 8, 13, 18). Hybrids in the “A Group” (not statistically different from the highest yielding hybrid) are listed below for each trial and test (click the image to view larger size).
