The CST program consist of large, on-farm strip trials across the state to evaluate yield performance and adaptability of new and commonly used varieties/hybrids.   We have a lot of good offerings to choose from when selecting varieties and hybrids to plant each spring. We hope that this data will give you a non-bias look into performance and aid in selecting your seed for the following crop with confidence.

We really appreciate all those who contributed to this data (County Agents, TN Farmers, Industry Seed Partners)

For more information on CST data or to book a trial on your farm next year, please contact your local County Extension Office.

On behalf of UT Extension, the West Tennessee Grain Conference Planning Committee invites you to attend the annual West Tennessee Grain and Soybean Producers Conference.
Details for this meeting and others are below.

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).

Several questions have come in this week regarding longer-term grain storage. Commodity prices for both corn and soy have prompted this question as producers look to 2025 futures. How long grain can be safely stored without a degradation in quality depends on several factors.
