The 2018 TN Cotton Variety Guide is now available  online. This document summarizes results from the 2017 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 days.  Summary tables from the 2017 season were calculated from six Official Variety Trials (OVTs), three large, replicated on-farm trials and thirteen 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.

Special thanks to all those who participated and/or contributed to the program during the 2016 growing season. See more here: W285

Juvenile leaves in regrowth have been an issue this year, both where plants shut-down prior to the first harvest aid application and where a substantial period of time has passed since the last harvest aid application.    This blog article highlights the important aspects of removing juvenile growth with a follow-up harvest aid shot.

If historical weather trends are true and our forecast holds, we are staring at one of the last opportunities to use moderate to warm temperatures to coax leaves off and open bolls.  The long term forecast suggests low temperatures next week will consistently fall below 60F with a few nights forecast to touch the low 50s.  Furthermore, rain is in the forecast over the weekend/through the beginning of next week.

Defoliation as temperatures begin to drop

The past two weeks have been excellent for defoliation.  Clear skies, nighttime temperatures in excess of 65F degrees, and very few scattered showers have allowed many to shed green leaves and open bolls quickly.  Unfortunately, the end of this week is forecast to bring much lower nighttime temperatures; several nights are expected to hit the low 50s.  The good news-  chances for rain over the next week are slim, daytime temperatures are still relatively warm, and only a few days are forecast to be partly cloudy.  Still, as temperatures begin to drop, products and rates will need to be altered.   Continue reading →

August felt more like September and the first few days of September forced many to rummage through the closet for a jacket.  Still, it appears we’ve been given an excellent window for harvest aids over the next 10 days; the temperatures in the forecast bring all products back to the table.   Continue reading →

The Mid-South’s cotton crop is rapidly maturing and many of our acres will receive a harvest aid application soon after Hurricane Irma moves through the area.  There are many factors to consider in determining timing, products and rates.   In an effort to outline these decisions and provide harvest aid recommendations for the Mid-South, the 2017 Mid-South Cotton Defoliation Guide has just been updated by the MidSouth Cotton Specialists’ Working Group and is now available online.   To access the guide, click the image above or the included link.  Please keep in mind that this was compiled as a regional guide and should be used in conjunction with your previous experiences.

Heat unit accumulation during 2017

Author:  Comments Off on Heat unit accumulation during 2017

Heat unit accumulation has been the big question over the past week.  Mild temperatures settled over Tennessee during early August and there is some concern that the crop may not be maturing as quickly as noted in years past.  While I agree the weather has been quite comfortable, we are currently very close to the 30 year average heat unit accumulation trend noted from 1980-2010.
