The 2019 County Standardized Trial-Soybean Results are now available.
This year, the trials evaluated 88 soybean varieties from 15 companies at 71 locations. Across all varieties and maturities, the tests averaged just over 60 bu/ac. Sufficient rains and soil moisture got this crop off to a great start and earlier planted beans showed no sign of drought stress in most locations. As the season went on, July and August offered little rain to much of TN and later planted beans suffered during pod fill and showed reduced yields in many locations. Maturity and herbicide tolerance is split into 6 protocols. Glyphosate/Dicamba tolerant varieties are tested in four separate trials; late MG III, early MG IV, late MG IV, and early MG V. Our Glufosinate tolerant trial, now hosting some 2-4-D tolerant varieties are separated into two trials; early MG IV and late MG IV.
While the finish line is either within sight or has been reached by most, Tennessee still has several acres of cotton in the field. Several have reported fall out, or seed cotton on the ground, on some of these acres. There are several methods to estimate yield loss from fall out. This article explains string-out, fall out, the method for estimating harvest loss from lock counts and covers potential sources of error in the estimate. 
With the arctic blast in the forecast and the substantial number of cotton acres left in the field, several have recently asked about how to keep water in their cotton pickers moisture system from freezing. Some operators occasionally mix a small percentage of methanol with water to lower the freezing point of water, but extreme caution must be used with this liquid since it is highly flammable. This post includes a brief demonstration concerning methanol/water mixtures and freeze points of different mixtures. Please note prior to using methanol or any other liquid in your moisture system you should consult the manufacturer. 
The forecast lows for Thursday/Friday/Saturday/Sunday nights have bounced around over the past few days, but this morning they included a 26, 28, 28 and 31. I’ve passed many fields with a large percentage of large bolls in the upper canopy still closed. Today (10/29) is the day to make any last-ditch effort at opening those bolls; it is likely all bolls remaining closed after this weekend will freeze shut.
