PR-700: 2015 Alfalfa Grazing Tolerance Report

Joey Clark, Gene Olson, Ray Smith | Dec. 14, 2015 (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-701: 2015 Red and White Clover Grazing Tolerance Report

Joey Clark, Gene Olson, Ray Smith | Dec. 14, 2015 (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, green chop, soil improvement, and wildlife habitat. 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. This report summarizes research on the grazing tolerance of clover varieties when subjected to continuous grazing pressure.

PR-684: 2014 Cool-Season Grass Grazing Tolerance Report

Joey Clark, Garry Lacefield, Gene Olson, Tim Phillips, Ray Smith | Dec. 4, 2014 (New)

Cool-season grasses such as tall fescue and orchardgrass are the primary pasture grasses in Kentucky. Other species such as perennial ryegrass, festulolium, and prairie brome 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-650: 2012 Red and White Clover Grazing Tolerance Report

Joey Clark, Garry Lacefield, Gene Olson, Ray Smith | Dec. 5, 2012 (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, green chop, soil improvement, and wildlife habitat. This species is adapted to a wide range of climatic and soil conditions. Stands of improved varieties are generally productive for two and a half to three years, with the highest yields occurring in the year following establishment. Red clover is used primarily as a renovation legume for grass pastures. It is a dominant forage legume in Kentucky because it is relatively easy to establish and has high forage quality, high yield, and animal acceptance.
