I’ve recently received several calls concerning N applications on wheat. Although this cold front has made it easier to get across wet fields, it is still early for the first split in a late winter/early spring split-N application approach. To make the most of the first split, target ‘spring greenup’, or the period in which wheat breaks dormancy and begins to grow rapidly (typically Feekes 3 or Zadoks 25). Delaying applications until this point can help ensure the applied N is available to the developing crop by reducing the potential for N loss. The current N demand of the dormant crop Continue reading

2014 TN Cotton Variety Trial Results
The 2014 TN Cotton Variety Trial Results Publication (PB1742) is now available online. This document contains detailed results from all harvested trails in the 2014 University of Tennessee Cotton Variety Testing program. This expanded publication follows the recently published summary publication, 2015 TN Cotton Variety Guide (W285), which was released a few weeks ago.
The tech-trait diversity in the top performers highlights the excellent yield potential, stability and fiber quality currently available in commercial cultivars irregardless of tech platform. Given many of these currently-available varieties have been moved forward into new tech-trait platforms, it appears producers will be deciding between several very viable options for many years to come.

2014 Tennessee Wheat Quick Facts
With our fly-free date of October 15th just around the corner, several of us are beginning to think about wheat planting. As we enter this wheat season, I hope you will find utility in our hot-off-the-press 2014 Tennessee Wheat Quick Facts Publication (W 321)which is now available online. This document is Continue reading
Defoliation Timing in 2014
There comes a point late in the season where defoliation timing begins to lean more heavily on the forecast and historical temperature normals associated with the current date than our maturity measurements (NACBs, %open, uppermost harvestable boll maturity as determined by the sharp-knife technique, etc.). In West Tennessee, I would argue that we are very rapidly approaching that time frame. The 5 day forecast here on the 28th day of Sept. for West TN indicates the next few days appear to be very favorable Continue reading
2014 Defoliation Strip Trials
We have put out two strip trials in the past week and will be putting out several more in the weeks to come. For those interested in taking a look at how a few of these products are working now, I wanted to pass along coordinates and treatment descriptions. I will be updating this post as more trials go out.
Cotton Yield Monitoring with the Case-IH and Deere Pickers
Dr. Mike Buschermohle and Lori Duncan with the University of Tennessee have just released a new Focus On Cotton webinar covering the topic of cotton yield monitoring from the Deere platform. This timely, very informative release was accompanied by another webinar by Dr. Pedro Andradé-Sanchez with the University of Arizona covering cotton yield monitoring from the Case-IH platform (links below). As we inch closer to this harvest season I would encourage you to visit the Focus on Cotton website and watch these videos. Continue reading
2014 Mid-South Defoliation Guide
Cooler temperatures have arrived in West TN. Luckily, much of our cotton crop has made up a tremendous amount of lost ground over the past month and several fields will have received their first shot of defoliant by the end of next week. With this less-than-desirable forecast and generally late crop, I would again encourage you to know your crop, know your environment/forecast, and use this information to guide your product selection and timing.
