The 2018 TN Cotton Variety Trial Results Publication (PB1742) is now available online. This document contains detailed results from all harvested trails in the 2018 University of Tennessee Cotton Variety Testing Program.  This expanded publication follows the recently published summary publication, the 2019 TN Cotton Variety Guide (W285) which was released a few weeks ago.


The tech-trait diversity in the top performers again highlights the excellent yield potential, stability and fiber quality currently available in commercial cultivars regardless of tech platform. Trial results reported from the 2018 season include 58 varieties entered into 7 Official Variety Trials (OVTs) and 18 varieties entered into 10 County Standard Trials (CSTs).  Both OVTs and CSTs were scattered throughout TN’s cotton producing counties.  Additionally, in-season plant measurements and multi-year yield averages were reported for the OVTs.

We will be releasing results from a June planted OVT later this winter, so keep an eye out for those results on this blog.

Special thanks to all those who participated and/or contributed to the program during the 2018 growing season, and look forward to seeing many of you during our 2019 meetings.

2018 County Standardized Trials (CST) wheat harvest data are now available.  Our county trial yields were consistent with yields in much of the state, down around 15 bu from what we had last year.  Late planting due to excess moisture and a cool, wet spring with delayed fertilizer and insecticide applications, didn’t get this crop set up for record year.
