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

Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Mar. 2, 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-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.

PR-773: 2019 Annual Grass Report: Warm Season and Cool Season (Cereals)

Bill Bruening, Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 12, 2019 (New)

Summer annual grasses provide an important forage crop option for producers in Kentucky. These grasses are mainly used as emergency or supplemental hay and pasture crops, but little information is available on their yield potential. The purpose of this publication is to summarize the University of Kentucky 2013-2019 forage yield trials with sudangrass, sorghum/sudangrass, millets, teff, and cereal crops. Cool season annual grasses (specifically cereal crops) are also used as forages crops for hay, baleage or grazing. The cereal crops used in this report are wheat (Triticum aestivum), rye (Secale cereale), oats (Avena sativa) and triticale (Triticum secale).

PR-771: 2019 Cool-Season Grass Grazing Tolerance Report

Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 5, 2019 (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 bromegrasses 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.

PR-772: 2019 Cool-Season Grass Horse Grazing Tolerance Report

Jimmy Henning, Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 5, 2019 (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

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-769: 2019 Alfalfa Grazing Tolerance Report

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