PR-728: 2017 Red and White Clover Report
Gene Olson, Ray Smith, Chris Teutsch | Nov. 27, 2017 (New)
This report provides current yield and persistence data on red and white clover varieties included in yield trials in Kentucky as well as guidelines for selecting clover varieties. Tables 13 and 14 show a summary of all clover varieties tested in Kentucky for the past 15 years. The UK Forage Extension website at www.uky.edu/Ag/Forage contains electronic versions of all forage variety testing reports from Kentucky and surrounding states and a large number of other forage publications.
PR-725: 2017 Kentucky Hybrid Corn Performance Test
Cam Kenimer, Chad Lee, Brandon Roberts | Nov. 2, 2017 (New)
The objective of the Kentucky Hybrid Corn Performance Test is to provide relative performance estimates of hybrid seed corn sold in Kentucky. The test attempts to treat every hybrid similarly in an unbiased manner. Agronomic practices that meet or exceed university guidelines are implemented at each location.
ID-247: Pastured Poultry
Jacquie Jacob, Tony Pescatore, Ray Smith | Sep. 21, 2017 (New)
There has been an increased interest in pasture-raising poultry for both meat and egg production in the last decade. Raising poultry on pasture was a common occurrence until the latter half of the 20th century. Fresh forage provided an important ration balancing factor during the years before poultry nutritionists fully understood the required essential vitamins and minerals for growth and optimum meat and egg production. With the development of balanced rations, poultry no longer require access to pasture and year-round production of meat and eggs is possible. However, there are still some benefits from the lush forage, invertebrates, and exercise that pasture provides. In addition, we continue to learn more and more about the positive influence that fresh grasses and legumes have on fatty acid profiles and general bird health. As a result, there is an increased interest in pasture-raised poultry for both meat and eggs.
PR-724: 2017 Kentucky Small Grains Variety Performance Test
Bill Bruening, Anthony Clark, John Connelly, Gene Olson, Brandon Roberts, Sandy Swanson, Dave Van Sanford | Jun. 28, 2017 (New)
The objective of the Kentucky small grain variety performance test is to evaluate varieties of wheat, oat, barley, triticale and cereal rye that are commercially available or may soon be available to Kentucky farmers. Annual evaluation of small grain varieties and selections provides farmers, seed producers, and other agricultural workers with current information to help them select the varieties best adapted to their locality and individual requirements.
AGR-228: Optimizing Bermudagrass Athletic Field Winter Survival in the Transition Zone
Gregg Munshaw | May. 31, 2017 (New)
Bermudagrass is an excellent choice for use on athletic fields throughout the transition zone (which includes Virginia, Kentucky, southern Indiana, and Missouri) because of its tolerance to close cutting heights, summer vigor, positive traction characteristics for athletes, resistance to divoting and ability to withstand and recover from significant traffic during active growth. The major limitation to successful bermudagrass persistence in transition zone locations is a general lack of cold tolerance and susceptibility to winterkill.
PPA-30: Sampling for the Tall Fescue Endophyte in Pasture or Hay Stands
Ray Smith, Tina Tillery, Paul Vincelli | Apr. 10, 2017 (Minor Revision)
Most of the tall fescue growing in Kentucky is colonized by the tall fescue endophyte, a fungus which causes disorders in livestock that feed on the infected grass. The animal disease syndrome is called fescue toxicosis, which some researchers estimate may cost Kentucky producers over $200 million yearly. This problem can be greatly reduced by identifying the infected fields and replacing them with endophyte-free or novel endophyte tall fescue varieties or by managing them in a way to minimize the impact of the endophyte on herd productivity. One of the simplest ways to reduce toxicity symptoms in cattle is add red and white clover to existing tall fescue stands.
AGR-227: Identifying Canola Growth Stages
Carrie Knott | Feb. 6, 2017 (New)
To effectively manage canola in Kentucky, the ability to identify key developmental growth stages is important. The most common canola growth stage system describes developmental stages. Several canola growth stages are important for Kentucky producers to recognize for optimal crop management and to maximize grain yield and profitability.
AGR-225: Turfgrass Weed Control for Professionals, 2017
Gregg Munshaw | Jan. 19, 2017 (New)
This newly expanded guide provides weed identification and control information that turfgrass professionals can use to develop effective weed control programs for golf courses, athletic fields, sod farms, lawns, and other turfgrass systems. The recommendations apply to the majority of the United States, with input from experts in Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, New York, Ohio, and Wisconsin. Available for purchase from Purdue University.
AGR-226: Identification and Control of Henbit and Purple Deadnettle
Mike Barrett, Gregg Munshaw | Dec. 30, 2016 (New)
Most of the winter annual broadleaf weeds are distinguishable from each other and thus fairly easy to key out or identify. However, there are two that show up each spring that often get people scratching their heads as to which is which--is it purple deadnettle? Or is it henbit? There are several similarities between these weeds--both are members of the mint family, both have square stems, both have sparsely hairy oval- to egg-shaped leaves, leaves of both are opposite, and both have small purple flowers that appear in the axils of the upper leaves during the spring.
PR-709: 2016 Alfalfa Report
Gene Olson, Ray Smith | Dec. 13, 2016 (New)
Alfalfa (Medicago sativa) has historically been the highestyielding, highest-quality forage legume grown in Kentucky. It is an important part of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets. Choosing a good variety is a key step in establishing a stand of alfalfa. The choice of variety can impact yield, thickness of stand, and persistence. This report provides yield data on alfalfa varieties included in current yield trials in Kentucky as well as guidelines for selecting alfalfa varieties.
