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.
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.
As harvest progresses for our major commodities, it is time to start planning and planting cover crops. Cover crops offer many benefits to agronomic systems, including erosion control, improvement to soil health, nutrient retention and additions, and weed suppression. How do we maximize these benefits? A key component is finding the right species, and varieties within those species. Just like corn, soybean, and cotton, that “right” variety is going to depend on your region and cropping system.
To help our growers find the best cover crop varieties for their region and system, we have been running a cover crop variety trial in Tennessee since 2019. We are excited to collaborate with the Southern Cover Crops Council this year to expand this trial and cover a 10-state region in the South. If you are in AL, AR, FL, GA, KY, NC, SC, TN, TX, or VA, we’ve got you covered! In this year’s report, you will find information important to maximizing those cover crop benefits, including cover crop biomass, canopy cover, and estimated nitrogen release, along with forage quality values for those who may be using cover crops for grazing (IVTDMD, CP, ADF, NDF, Lignin).
This past year was an odd one, with a cold snap in December that burst pipes across the South and was not so kind to some of our cover crop species. This does not reflect a typical year (at least I hope that isn’t our new normal!). For information on some of those more cold-sensitive species, looking at previous year’s reports may be helpful.
Results from the 2022 TN soybean variety trials are now available as pdf and excel files and will be posted at search.utcrops.com/soybean. Seventy-five varieties were evaluated in small plot replicated trials (REC) at nine locations and fifty-seven varieties were evaluated in three to nine locations as non-replicated large strip plots (CST). Quality and agronomic traits are reported for the REC trials and disease data are reported for CST trials. A summary of varieties that were in the yield “A group” (not statistically different from the top yield within each test) in either the REC or CST trial can be viewed here 2022 Soybean A Table.
Results from the 2022 TN corn grain hybrid trials are now available as both pdf and excel files. Sixty hybrids were evaluated in small plot replicated trials (REC) at eight locations and fifty-one hybrids were evaluated as non-replicated large strip plots (CST) in thirteen to seventeen locations. A summary of hybrids that were in the “A group” (not statistically different from the top yield within each test) in either the REC or CST trial can be found here – 2022 corn A table.
Our 2022 cover crop variety trial results are in! If you are thinking about putting in a cover crop this fall, check out which varieties and mixes did best. Entries were evaluated in both an early and late planted trial (early Oct., early Nov.) and under two termination timings (early Apr., early May). In addition to information on biomass, our report has data on which cover crops provided the best canopy cover throughout the season, estimated nitrogen release to the succeeding cash crop, and forage characteristics for those interested in grazing their covers. 21-22 TN Cover Crop Variety Test Report
Results from the 2021 TN soybean variety trials are now available as pdf and excel files at search.utcrops.com/soybean. One hundred ten varieties were evaluated in small plot replicated trials (REC) at nine locations and fifty-seven varieties were evaluated in three to twelve locations as non-replicated large strip plots (CST). Quality and agronomic traits are reported for the REC trials and disease data are reported for both sets of trials. A summary of varieties that were in the yield “A group” (not statistically different from the top yield within each test) in either the REC or CST trial can be viewed here 2021 TN Soybean Top-Performers . Links for individual tables and the soybean database will be uploaded soon.
