PR-787: 2020 Alfalfa Grazing Tolerance Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 23, 2020 (New)
Alfalfa (Medicago sativa) is the highest-yielding, highest-quality forage legume grown in Kentucky. It forms the basis of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets. Recent emphasis on its use as a grazing crop and the release of grazing-tolerant varieties have raised the following question: Do varieties differ in tolerance to grazing? We have chosen to use the standard tolerance test recommended by the North American Alfalfa Improvement Conference. This test uses continuous heavy grazing to sort out differences in grazing tolerance in a relatively short period of time. This report summarizes research on the grazing tolerance of alfalfa varieties when subjected to continuous heavy grazing pressure during the grazing season.
PR-788: 2020 Red and White Clover Grazing Tolerance Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 23, 2020 (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-785: 2020 Timothy and Kentucky Bluegrass Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Nov. 20, 2020 (New)
Timothy (Phleum pratense) is the fourth most widely sown cool-season perennial grass used in Kentucky for forage--after tall fescue, orchardgrass, and Kentucky bluegrass. It is a late-maturing bunchgrass that is primarily harvested as hay, particularly for horses. It also can be used for grazing or wildlife habitat. Kentucky bluegrass (Poa pratensis) is a high-quality, highly palatable, long-lived pasture plant with limited use for hay. It tolerates close, frequent grazing better than most grasses. It has low yields and low summer production and becomes dormant and brown during hot, dry summers. Kentucky bluegrass is slow to establish.
PR-786: 2020 Annual and Perennial Ryegrass and Festulolium Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Nov. 20, 2020 (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-781: 2020 Alfalfa Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 16, 2020 (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-782: 2020 Red and White Clover Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 16, 2020 (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-767: 2019 Timothy and Kentucky Bluegrass Report

PR-774: 2019 Long-Term Summary of Kentucky Forage Variety Trials
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 18, 2019 (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.
