PR-751: 2018 Cool-Season Grass Grazing Tolerance Report
Joey Clark, Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | November 27, 2018 (New)
Cool-season grasses such as tall fescue, orchardgrass, and Kentucky bluegrass are the primary pasture grasses in Kentucky. Other species such as perennial ryegrass, festulolium, and the brome grasses can be used in pasture systems. Little is known about the effect of variety on the grazing tolerance of these cool-season grass species. The purpose of this report is to summarize current research on the grazing tolerance of varieties of tall fescue, orchardgrass, perennial ryegrass, and other species when they are subjected to continuous, heavy grazing pressure by cattle within the grazing season. The main focus will be on plant stand survival.
PR-745: 2018 Orchardgrass Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | November 20, 2018 (New)
This report provides current yield data on orchardgrass varieties included in yield trials in Kentucky as well as guidelines for selecting orchardgrass varieties. Table 11 shows a summary of all orchardgrass varieties tested in Kentucky for the last 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 from a large number of other forage publications.
PR-744: 2018 Red and White Clover Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | November 19, 2018 (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 12 and 13 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-743: 2018 Alfalfa Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | November 19, 2018 (New)
This report provides yield data on alfalfa varieties included in current yield trials in Kentucky as well as guidelines for selecting alfalfa varieties. Tables 14 and 15 (Roundup Ready varieties) shows a summary of all alfalfa varieties tested in Kentucky during the past 16 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 as well as a large number of other forage publications.
AGR-238: Establishing and Managing Bermudagrasses in the Transition Zone
Gregg Munshaw, Travis Shaddox | November 12, 2018 (New)
Bermudagrasses have been successfully grown on athletic fields and golf courses in the transition zone for many years. Although each year some level of winterkill threat exists, bermudagrass remains an excellent surface for golf and sports. Seeded varieties of bermudagrasses have been the most common choices in Kentucky due to the availability of seed of good varieties as well as the ease of planting seed versus living plant material. There are, however, several outstanding vegetative bermudagrass cultivars that are adapted to the transition zone.
PR-756: 2018 Kentucky Hybrid Corn Performance Test
Cam Kenimer, Chad Lee, M.W. Piersawl | October 26, 2018 (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-250: An Introduction to Industrial Hemp and Hemp Agronomy
Rich Mundell, David Williams | July 20, 2018 (New)
Cannabis sativa is a summer annual plant that is strongly photoperiod-sensitive (flowers according to day length/photoperiod; not physiological maturity). It is mostly dioecious in that male and female flowers occur on separate plants (i.e. there are both male plants and female plants). However, there are also several monoecious commercial varieties (male and female flower parts on the same plant). Different plant parts are harvested for specific purposes, and modern day hemp may be produced for one or more purposes. Depending on the harvestable component of interest, (i.e. fiber, grain or cannabinoids) male plants and/or pollen might be vitally necessary or completely unwanted.
PR-742: 2018 Kentucky Small Grains Variety Performance Test
Bill Bruening, John Connelly, Gene Olson, M.W. Piersawl, Sandy Swanson, Dave Sanford | July 3, 2018 (New)
The 2018 soft red winter wheat growing season ended with Kentucky farmers harvesting approximately 300,000 acres of the 440,000 acres planted, for a total production of 24 million bushels of grain. An average yield of 80 bushels per acre was estimated by NASS, but that figure may be reduced due to the shorter seed filling period associated with persistent high temperatures in May. The acreage not harvested for grain was primarily used for forage production and cover cropping.
ID-249: A Comprehensive Guide to Soybean Management in Kentucky
Ric Bessin, Carl Bradley, J.D. Green, John Grove, Greg Halich, Erin Haramoto, Carrie Knott, Chad Lee, Travis Legleiter, Josh McGrath, Sam McNeill, Javier Reyes, Edwin Ritchey, Montse Salmeron, Jordan Shockley, Claire Venard, Raul Villanueva, Ole Wendroth, Kiersten Wise, Xi Zhang | June 7, 2018 (New)
This publication provides information on soybean growth and development, principles of variety selection, and management practices to maximize soybean profitability in Kentucky.
AGR-148: Weed Control in Alfalfa and Other Forage Legume Crops
J.D. Green, Travis Legleiter | April 23, 2018 (Major Revision)
The importance of weed control in forage production should not be overlooked, especially when you consider the high investment associated with alfalfa and other legume forages. Weeds reduce forage yield by competing for water, sunlight, and nutrients. In addition to yield losses, weeds can also lower forage quality, increase the incidence of disease and insect problems, cause premature stand loss, and create harvesting problems. Some weeds are unpalatable to livestock or, in some cases, may be poisonous.
