AGR-238: Establishing and Managing Bermudagrasses in the Transition Zone

Gregg Munshaw, Travis Shaddox | Nov. 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 | Oct. 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 | Jul. 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 | Jul. 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.

AGR-148: Weed Control in Alfalfa and Other Forage Legume Crops

J.D. Green, Travis Legleiter | Apr. 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.

AGR-175: Forage Identification and Use Guide

David Ditsch, Jimmy Henning, Garry Lacefield, Ray Smith | Mar. 28, 2018 (Reprinted)

Forage crops occupy approximately 7 million acres in Kentucky. They provide most of the feed for beef, dairy, horse, sheep, and wildlife. In addition, forage crops play a critical role in soil conservation, water quality, and air quality. The purpose of this publication is to provide both agronomic and identification information on several forage grasses and legumes.

AGR-236: Managing Frost Damaged Alfalfa Stands

Matthew Dixon, Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch | Mar. 19, 2018 (New)

Wide fluctuations in springtime temperature are common in Kentucky. Late freezing temperatures in the spring can cause damage to alfalfa depending on how far along it is in breaking dormancy. This publication provides information on the effect of low spring temperatures on both established and new alfalfa stands that have begun growth, as well as a method of predicting sensitivity to late frosts or freezes.

AGR-229: Warm Season Annual Grasses in Kentucky

Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch | Mar. 5, 2018 (New)

In Kentucky, cool-season grasses produce ample forage in the spring and fall, but high temperatures and short-term drought stress often limits growth during the summer months. Warm-season annual grasses can fill this gap with relatively high quality forage when properly managed. The purpose of this publication is to provide an overview of the various summer annuals for Kentucky.

AGR-237: Grass Options for Athletic Fields in the Transition Zone

Nicole Mundell | Mar. 2, 2018 (New)

There are several grasses that will grow in the transition zone, but none all that well. Our summers are often too hot for cool-season grasses like Kentucky bluegrass and our winters are often too cold for warm-season grasses like bermudagrass. Keep in mind, however, that the problem with most poor athletic fields is not grass selection, but rather over use, lack of maintenance, and/or use when field is wet or cannot recover.
