Tennessee Market Highlights
Author: Chuck Danehower, Extension Area Specialist - Farm Management No Comments

Cotton was up; wheat was mixed; corn and soybeans were down for the week. Harvest corn futures continued to trade sideways for the sixth consec-utive week. Average domestic corn yields are very likely to exceed the 2009 record of 164.7 bpa. Many analysts have 2014 yield estimates above 170 bpa (the USDA estimated yields at 167.4 bpa in the August WASDE). As a result of the estimated record yield, 2014 corn production is estimated at 14.031 billion bushels (above the current record of 13.925 billion bushels set in 2013).

Heat unit status in cotton
Author: Dave Verbree, Crop Physiologist and Agronomist No Comments

Dave Verbree and Tyson Raper

As of 8/26/14, this cooler than normal year has set cotton back by 166-215 heat units depending on the planting date (Table 1). Based on the 30-yr average, we typically accumulate about 18.5 DD60s/day during this time of year which puts our cotton 9-12 days behind schedule. However, we have been accumulating about 23 DD60s/day over the past 5 days which is helping us catch up. Unfortunately, the number of DD60s per day normally begins to drop about 0.2 degrees each day at this time of year.

We need about 1625 DD60s to reach 1st open boll and some of those who planted timely, did not over-fertilize, and managed for earliness are already there. We need about 2200 DD60s to reach maturity so we hope the above average temperatures will stick around a few more weeks. Realistically, most of us should expect cool temperatures during defoliation and plan to use a two-pass approach, relying more on our herbicidal defoliants to finish off the job. We will post more about defoliation in the coming weeks.

SCATTERED SHOWERS PROVIDE RELIEF TO CROPS

In spite of the rapid return to more normal August temperatures, rains over some crop producing areas provided a needed boost. In some areas, dry conditions still persist and crop and pasture stress is prevalent. Cotton growers would feel more comfortable with their crop getting more heat units before our first frost. Through all the up and down weather this season, crops production is expected to be normal to above normal. Continue reading at Crop Progress 8 24 14

Aerial Sowing Cover Crops for Weed Control
Author: Larry Steckel, Extension Weed Specialist 2 Comments

Aerial sowing cover crop questions have been numerous this month.  Indeed the wet month of August does greatly increase the probability that aerial seeding will be successful as we enter September.  This was the case last year where aerial seeding cover crop into standing crops in September was quite successful for many.  Continue reading

Madison County Standard Test Demonstration
Author: Tyson Raper, Cotton & Small Grains Specialist No Comments

DSC_0078We’ve got some really nice differences between varieties showing up in the County Standard Test Demonstration located here on the West Tennessee Research and Education Center (605 Airways Blvd., Jackson, TN 38301).  I would encourage anyone interested in a side-by-side comparison of varieties to take a look at these strip-plots.  This demonstration is located immediately adjacent to the station’s front entrance on the right.  Coordinates for the southwest corner are lat 35.618224°, lon -88.846448°.  Variety signs are located in the 2nd row of each 4 row plot.
