2017 County Standardized Trial (CST) Wheat yield data is now complete. CST plots are large on-farm strip trials using farmers normal production practices, and represent common production environments. Included in the table are 12 test, harvested from 11 counties across much of West TN and into Middle TN coving a wide range of Continue reading
The University of Tennessee Variety Testing team is pleased to announce the launch of a new search tool for yield and agronomic data for corn grain and silage, cotton, soybeans and wheat. Continue reading
Yesterday, I had the opportunity to visit some fields in Shelby County and had reports from a couple of other areas where armyworms have completely defoliated some wheat fields (or spots in fields). Armyworms were not hard to find, but many had pupated (“cycled out”) or were being killed by diseases and parasites. The good news is Continue reading
This is a repeat of an older article … as a reminder. There have been a couple of reports of armyworms in wheat. Nothing crazy but much of the wheat is still in the milk stage and would be susceptible to excessive defoliation. Occasionally, armyworms may even cut the heads, typically when populations are high. Yield loss is most likley if Continue reading
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!
It will be the end of next week (March 24) before we can tell how badly the wheat was injured from the cold temperatures this week. Of course, a decade ago we had a similar cold spell that many folks refer to as the Easter freeze. Back then some fields were destroyed and replanted to other crops while others were kept and went to yield. Then as now when making this decision the herbicides that have been applied to the wheat must play a factor in how to proceed. Continue reading
For much of Tennessee’s wheat, the cold front which moved through Saturday (March 11th) dropped temperatures near the danger zone. Jointing typically does not occur until late March but our mild winter has allowed much of the timely planted wheat to mature faster than normal. Much of our wheat is between Feekes stages 7 and 8. In the below image, the growing point was located near the knife blade. Wheat becomes considerably less tolerant to cold temperatures after the growing point leaves the base of the plant.

The new publication, “W 403: Verticillium Wilt in Tennessee Valley Cotton” provides background on Verticillium wilt, summarizes recent variety trial results, and highlights other practices that can reduce the impact of the disease. Continue reading
