2018 Soybean Variety Tests in Tennessee – Prelim Report

Author:  Comments Off on 2018 Soybean Variety Tests in Tennessee – Prelim Report

Our 2018 Tennessee Soybean Variety Trials report is nearly complete!   Results for yield and agronomic traits are now available – 2018 Soybean Variety Tests in Tennessee – PRELIM. Disease data will be updated early next week.  In the next week or so, these results will also be posted as mobile-friendly, searchable, sortable tables at

Thank you for your patience this year.  We pride ourselves on getting data to you as quickly as possible, but, as most of you are aware, this has been a challenging harvest season for soybeans. Persistent rains delayed harvest for many of our variety trial locations, with the county standard tests seeing the worst of these delays. Fewer county locations are reported this year due to issues related to weather delays. In spite of the delayed harvest, yields for the majority of tests were good, averaging 54.8 bu/ac in the research center tests and 53.7 bu/ac in the county tests. Several varieties with average yields exceeding 60 bu/ac were observed.

Be sure to check back next week for updated disease data and excel tables.

As promised, our 2018 TN corn grain hybrid trial data has been finalized and is now available. Follow these links for the full pdf and all excel tables.  We are still working on getting our web-friendly, sortable, and searchable tables up on  I’ll post to the blog as soon as they are available, which should be sometime next week.

Due to persistent rain delaying harvest at some locations, our soybean variety trials data is likely still a week or two away, but will be posted as soon as possible!

2018 Corn Silage Hybrid Trials Report Now Available

Author:  Comments Off on 2018 Corn Silage Hybrid Trials Report Now Available

Our 2018 Corn Silage hybrid trials data has been finalized and is now available on . Here you can find the full pdf version of the report  as well as all tables in either excel format or as web-friendly, sortable and searchable tables.

The online tables have some nice features for finding the data you want quickly and easily.  Here are a few tips for viewing online.

  • Be sure to scroll to the right to view all columns.
  • Use the “previous” and “next” button to see all entries.
  • By default, columns are sorted by yield. If you’d like to sort  by a different column, just click on the column title.
  • If you are looking for a specific hybrid or trait package, the search feature is especially useful.  Just type what you are looking for into the “Search” box at the top right of the table.  For example, typing “TN” brings up all of our TN experimental lines in the test while typing “LL” displays all hybrids that had LL listed in their herbicide trait package.

New this year, we have 1 yr, 2 yr, and 3 yr data in the same table so that you can easily see which hybrids have been evaluated over multiple years and how they performed. Mean separation (MS) letters are also now given for each trait evaluated, rather than just yield. This allows for easy identification of top-performing hybrids for either yield, agronomic, or quality traits. Hybrids that have any MS letter in common, within a column, are not significantly different for that trait.

Be on the lookout for our corn grain prelim report to be posted within the next week!


Tennnessee Variety Test Program Survey

Author:  Comments Off on Tennnessee Variety Test Program Survey

Things have been busy this past month in the Tennessee variety test program as entries continue to roll in for our 2017 corn and soybean tests. This year we will be testing a total of 86 corn grain hybrids, 11 corn silage hybrids, and 195 soybean varieties across the state of Tennessee.

We know the variety test program is important to many of you. In order to make sure this program continues to meet your needs, we’d like some feedback from you!

If you are a Tennessee corn, soybean, wheat, or cotton producer, please take a few minutes to help us out by taking this survey. Producer – Variety Test Survey

If you are not a producer, but you provide folks with advice on variety selection (scout, retailer, seed company rep), then please take this survey. Industry – Variety Test Survey

Thanks for your help as we continue to figure out ways we can better serve you through our Tennessee variety test program!
