2015 Corn Hybrid Performance Test Online

Cam Kenimer, Corn Hybrid Trial Coordinator, University of Kentucky
Chad Lee, Extension Agronomist, University of Kentucky

The 2015 University of Kentucky Corn Hybrid Performance Trials are now online. Seed companies submitted 151 hybrids to be tested. The hybrids were divided into Early, Medium, Late, and White groupings.

The range from best to worst hybrid was 35.6 bushels per acre for the Early hybrids. The range for the Medium hybrids was even greater at 45.4 bushels per acre. The range in yields was 33.3 bushels per acre for the Late hybrids. Based solely on yield performance and the current market price for corn, those ranges equate to about $125 to $175 per acre difference between the highest and lowest yielding hybrid.

2015 Corn Silage Hybrid Report Available

Nick Roy, ANR Extension Agent, Adair County, University of Kentucky
Chad Lee, Extension Professor, University of Kentucky

The 2015 Corn Silage Hybrid Trial is available online. and is linked to the variety testing page.  The test evaluated 20 hybrids submitted by 10 seed companies. A test was conducted in three locations in Kentucky: Green County, Boyle County and Bracken County. All yields were corrected to 35% dry matter. There was a yield difference of 5.9 tons/acre between the highest and lowest yielding hybrid for this. Forage quality tests combined with yield allowed us to estimate milk production for each hybrid. There potential milk production difference from the best and worst performing hybrid was 11,652 pounds per acre. Based on current milk prices, that is worth $2,323 of milk per acre.

Simply choosing the correct hybrids could greatly impact the bottom line. Hybrid selection should always be based off of performance across multiple locations. We encourage you to compare the results from this trial to results from other non-biased trials. If you have questions about this test, contact your local county extension agent.

Fall Nitrogen Considerations for Wheat in 2015

Edwin Ritchey, Lloyd Murdock, and Josh McGrath – Extension Soil Specialists, University of Kentucky

Many producers have completed or almost completed corn harvest and getting ready to start drilling wheat. One question that keeps coming up is the need for a fall nitrogen (N) application. In most years there is adequate residual N following corn. However most areas in Kentucky in 2015 had very good corn yields and a considerable amount of rainfall earlier in the season. Good corn yields coupled with high rainfall probably means that there is very little residual N remaining in the soil profile. Numerous studies at UK have not shown a consistent yield advantage to fall N applications for wheat. However, fall N does stimulate growth and establishment of the stand. Too much fall N could reduce yields by causing excessive growth and more winterkill.

Wheat Product Test Reveals Little Help for Yields

John H. Grove and William P. Bruening
Plant and Soil Sciences Department, University of Kentucky
The following is a progress report to the Kentucky Small Grains Growers Association.

The primary goal of this research is to provide new product information to wheat producers. New product releases, which occur every year, are often accompanied by weak performance evaluation information – often testimonials based on invalid comparisons. Chemical soil compaction treatments, liquid carbon and foliar nutrition products are already in the marketplace, and a new group of ‘biological/microbiological’ products is now emerging. Are any of these new materials going to be the “next big thing” in wheat production? The objective was to evaluate nine products intended to raise Kentucky wheat yield. Six products were specified by the Kentucky Small Grain Growers Association.

New Corn Disease Found in Bordering States

Carl A. Bradley, University of Kentucky Extension Plant Pathologist
Originally posted in KPN

Tar spot of corn, a foliar disease caused by the fungus Phyllachora maydis, recently was found in the United States for the first time. The disease was confirmed in Indiana and Illinois. Pictures of the disease and more information about the locations where its presence was confirmed are available online in the Pest & Crop Newsletter (Purdue Cooperative Extension Service) and the Bulletin (University of Illinois Extension).

It is important to document if this disease is present in Kentucky. If symptoms similar to those shown in the articles referenced above are found in Kentucky, samples should be submitted to one of the University of Kentucky Plant Disease Diagnostic Laboratories (located in Princeton and Lexington) via a county Extension agent.

Winter Decline Syndrome of Canola (PPFS-AG-R-01)

Carl Bradley, Extension Plant Pathologist, University of Kentucky

Interest in producing canola in Kentucky has greatly increased in recent years. During the last canola “boom” in Kentucky during the late 1980s, a serious concern was the rapid decline of stands during late winter and early spring. Referred to as winter decline syndrome, the problem was so severe in some fields that near complete crop failure occurred. At present, it is unknown if newer canola cultivars — with reported improved winter hardiness and survival — will be less subject to winter decline syndrome or not. This publication is intended to help canola producers become familiar with winter decline syndrome, its symptoms, its possible cause, and management options. 

Winter Decline Syndrome of Canola (PPFS-AG-R-01) is available online. For additional publications on crop diseases, visit the UK Plant Pathology Extension Publications webpage
