PR-736: 2017 Cool-Season Grass Horse Grazing Tolerance Report

Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 13, 2017 (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-733: 2017 Alfalfa Grazing Tolerance Report

Joey Clark, Gene Olson, Ray Smith, Chris Teutsch | Dec. 11, 2017 (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-734: 2017 Red and White Clover Grazing Tolerance Report

Joey Clark, Gene Olson, Ray Smith, Chris Teutsch | Dec. 11, 2017 (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-724: 2017 Kentucky Small Grains Variety Performance Test

Bill Bruening, Anthony Clark, John Connelly, Gene Olson, Brandon Roberts, Sandy Swanson, Dave Van Sanford | Jun. 28, 2017 (New)

The objective of the Kentucky small grain variety performance test is to evaluate varieties of wheat, oat, barley, triticale and cereal rye that are commercially available or may soon be available to Kentucky farmers. Annual evaluation of small grain varieties and selections provides farmers, seed producers, and other agricultural workers with current information to help them select the varieties best adapted to their locality and individual requirements.
