2018 TN Cotton Variety Trial Results now available (PB1742)

Author: and  Comments Off on 2018 TN Cotton Variety Trial Results now available (PB1742)
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.

The 2019 Cotton Variety Guide is now available  online. This document summarizes results from the 2018 University of Tennessee Cotton Agronomy program and serves as a precursor to a full release of trial results in PB 1742 to come within the next few weeks.  Summary tables from the 2018 season were calculated from six Official Variety Trials (OVTs) and eight County Standard Trials (CSTs) scattered throughout TN’s cotton producing counties.  To access the document click the adjacent image or the hyperlinks above or below.

When should I resume picking?

Author:  Comments Off on When should I resume picking?

Weather over the past few days has allowed our cotton crop to dry down substantially. Still, it is unlikely the areas which noted sprouting will be dry enough to pick until mid-week (Oct. 3). In this post, I cover the factors to consider and potential impacts should you rush into harvest before the crop has sufficiently dried.  Continue reading


After sprouting: Protecting existing cotton fiber quality

Author:  Comments Off on After sprouting: Protecting existing cotton fiber quality

The past six days of rain found the vast majority of our Upper-MidSouth cotton crop defoliated and open.  Unfortunately, these conditions supported emergence of cottonseed while still within the boll- commonly referred to as sprouting.  In this blog, I briefly cover best management practices to protect the existing fiber quality.   Continue reading


Warm weather defoliation mixes (1 and 2 shot) with and without thidiazuron

Author:  Comments Off on Warm weather defoliation mixes (1 and 2 shot) with and without thidiazuron

Our forecast for the next 7 days contains ideal conditions for defoliating and opening bolls.  In this blog, I cover my current 1 and 2 shot go-to mixes and briefly describe how I would approach defoliation without thidiazuron.   Continue reading
