Brief Project Summary:

The goal of the University of Tennessee Variety Testing Program is to provide unbiased yield and agronomic data evaluated across the full range of physiographic regions represented in the state of Tennessee for crop varieties of different brands. Trials obtain comparative seed yield and agronomic trait data on varieties and experimental lines of soybeans that are or will be marketed in the state from head-to-head replicated trials at multiple locations. At the conclusion of each harvest season, test results are compiled, published and distributed to producers, agents, company personnel and other interested clientele.

Key Benefactors:
farmers, agronomists, extension agents

In 2020, 148 soybean varieties were submitted by 4 public institutions and 15 private companies (for evaluation in UT’s replicated small plot variety trials. Nine entries were dropped after the entry deadline resulting in evaluation of 139 varieties. Herbicide tolerance varied by entries with the majority of entries falling into the Roundup-Ready Xtend (R2X) category (61 entries) (Table 1). Other herbicide tolerance groups included Roundup-Ready (RR), Roundup-Ready 2 (RR2), Glyphosate tolerant (GT), Liberty-Link (LL), Enlist E3, Sulfonylurea tolerant (STS) and stacks of these traits. Total entries falling into each of these categories are given in Table 1. Varieties were divided by maturity group into the following tests: MG3 (9 entries), MG4E (35 entries), MG4L (72 entries), MG5 (23 entries). Replicated small plots were planted at AgriCenter International (Memphis) and the following AgResearch and Education Centers (REC): West Tennessee (Jackson), Highland Rim (Springfield; irrigated and non-irrigated tests), Middle Tennessee (Spring Hill), East Tennessee (Knoxville), and Milan (Milan; irrigated and non-irrigated tests). Harvest was completed 1 Dec. 2020 and results were analyzed and sent for review by industry collaborators. Results were posted on news.utcrops.com and search.utcrops.com on 10 Dec. 2020. Approximately two thousand copies of the “2020 Soybean Variety Tests in Tennessee” publication have been printed and will be distributed through UT Extension agents. A copy of this Extension publication can be found on https://search.utcrops.com/soybean.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
