PR-770: 2019 Red and White Clover Grazing Tolerance Report

Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 4, 2019 (New)

Red clover (Trifolium pratense L.) is a high-quality, short-lived perennial legume that is used in mixed or pure stands for pasture, hay, silage, soil improvement, and wildlife habitat. This species is adapted to a wide range of climatic and soil conditions. White clover (Trifolium repens L.) is a low-growing, perennial pasture legume with white flowers. It differs from red clover in that the stems (stolons) grow along the surface of the soil and can form adventitious roots that may lead to the development of new plants.

PR-765: 2019 Orchardgrass Report

Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Nov. 27, 2019 (New)

Orchardgrass (Dactylus glomerata) is a high-quality, productive, cool-season grass that is well-adapted to Kentucky conditions. This grass is used for pasture, hay, green chop, and silage, but it requires better management than tall fescue for greater yields, higher quality, and longer stand life. It produces an open, bunch-type sod, making it compatible with alfalfa or red clover as a pasture and hay crop or as habitat for wildlife. This report provides current yield data on orchardgrass varieties included in yield trials in Kentucky as well as guidelines for selecting orchardgrass varieties.

PR-768: 2019 Annual and Perennial Ryegrass and Festulolium Report

Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Nov. 27, 2019 (New)

Annual ryegrass (Lolium multiflorum) and perennial ryegrass (Lolium perenne) are high-quality, productive, cool-season grasses used in Kentucky. Both have exceptionally high seedling vigor and are highly palatable to livestock. Perennial ryegrass can be used as a short-lived hay or pasture plant and has growth characteristics similar to tall fescue. Festuloliums are hybrids between various fescues and ryegrasses with higher quality than tall fescue and improved stand survival over perennial ryegrass.

PR-763: 2019 Alfalfa Report

Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 26, 2019 (New)

Alfalfa (Medicago sativa) has historically been the highest-yielding, 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.

PR-766: 2019 Tall Fescue and Bromegrass Report

Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Nov. 26, 2019 (New)

Tall fescue (Festuca arundinacea) is a productive, well-adapted, persistent, soil-conserving, cool-season grass grown on approximately 5.5 million acres in Kentucky. This grass, used for both hay and pasture, is the forage base of most of Kentucky's livestock enterprises, particularly beef cattle. Much of the tall fescue in Kentuckys infected with an internal fungus (endophyte) that produces ergot alkaloids and results in decreased weight gains in growing ruminants and lower pregnancy rates in breeding stock, especially in hot weather. Varieties are now available that are free of this fungal endophyte or infected with a nontoxic endophyte. Varieties in the latter group are also referred to as "novel" or "friendly" endophyte varieties, because their endophyte improves stand survival without creating animal production problems

PR-764: 2019 Red and White Clover Report

Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 26, 2019 (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 14 and 15 show a summary of all clover varieties tested in Kentucky for the past 15 years. The UK Forage Extension website at forages.ca.uky.edu contains electronic versions of all forage variety testing reports from Kentucky and surrounding states and a large number of other forage publications.

PR-753: 2018 Annual Grass Report: Warm Season and Cool Season (Cereals)

Bill Bruening, Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 5, 2018 (New)

The major factor in selecting a variety of summer annual grass is yield, both total and seasonal. Growth after first cutting is strongly dependent on available moisture and nitrogen fertilization. Summer annual grasses generally have different characteristics and uses. The major factors in selecting cool season cereal grass varieties are yield, winter survival and regrowth.

PR-754: 2018 Long-Term Summary of Kentucky Forage Variety Trials

Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 5, 2018 (New)

Forage crops occupy approximately 7 million acres in Kentucky. Forages provide a majority of the nutrition for beef, dairy, horse, goat, sheep, and wildlife in the state. In addition, forage crops play an environmentally friendly role in soil conservation, water quality, and air quality. There are over 60 forage species adapted to the climate and soil conditions of Kentucky. Only 10 to 12 of these species occupy the majority of the acreage, but within these species there is a tremendous variation in varieties. This publication was developed to provide a user-friendly guide to choosing the best variety for producers based on a summary of forage yield and grazing tolerance trials conducted in Kentucky over the past 12 to 15 years.

PR-752: 2018 Cool-Season Grass Horse Grazing Tolerance Report

Jimmy Henning, Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Nov. 30, 2018 (New)

Cool-season grasses such as Kentucky bluegrass, tall fescue, and orchardgrass are dominant pasture grasses for horses in Kentucky. Variety evaluations for yield have been carried out for many years, but little work has been done to establish the effect of variety on persistence when subjected to close, continuous grazing by horses. The purpose of this report is to summarize current research on the grazing tolerance of varieties of tall fescue, orchardgrass, and other species when subjected to continuous heavy grazing pressure by horses within the grazing season. The main focus will be on stand survival.
