PR-711: 2016 Orchardgrass Report
Gene Olson, Tim Phillips, Ray Smith | November 30, 2016 (New)
Orchardgrass (Dactylus glomerata) is a high-quality, productive, cool-season grass that is welladapted 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-712: 2016 Tall Fescue and Bromegrass Report
Gene Olson, Tim Phillips, Ray Smith | November 30, 2016 (New)
Tall fescue 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. All bromegrasses have several advantages over tall fescue, including retaining quality as they mature and better growth during dry weather, but they are generally less well adapted in Kentucky. This report provides current yield data on tall fescue varieties and similar grass species in trials in Kentucky as well as guidelines for selecting tall fescue varieties, including summaries of all tall fescue and bromegrass varieties tested in Kentucky for the past 15 years.
PR-723: Kentucky Silage Hybrid Performance Test, 2016
David Appelman, Chad Lee, Jerry Little, Nick Roy, Will Stallard | November 28, 2016 (New)
The objective of the Silage Corn Hybrid Performance Test is to provide unbiased forage yield and quality data for corn hybrids commonly grown for silage in Kentucky.
PR-718: 2016 Cool-Season Grass Horse Grazing Tolerance Report
Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith | November 18, 2016 (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-717: 2016 Cool-Season Grass Grazing Tolerance Report
Joey Clark, Gene Olson, Tim Phillips, Ray Smith | November 18, 2016 (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 brome grasses 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-715: 2016 Alfalfa Grazing Tolerance Report
Joey Clark, Gene Olson, Ray Smith | November 17, 2016 (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-716: 2016 Red and White Clover Grazing Tolerance Report
Joey Clark, Gene Olson, Ray Smith | November 17, 2016 (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-708: 2016 Kentucky Hybrid Corn Performance Test
Ron Curd, Cam Kenimer, Chad Lee, Brandon Roberts | October 24, 2016 (New)
The objective of the Kentucky Hybrid Corn Performance Test is to provide relative performance estimates of hybrid seed corn sold in Kentucky. The test attempts to treat every hybrid similarly in an unbiased manner. Agronomic practices that meet or exceed university guidelines are implemented at each location.
PR-641: 2011 Nursery and Landscape Research Report
Sharon Bale, Win Dunwell, Rick Durham, Bill Fountain, Bob Geneve, John Hartman, Dewayne Ingram, John Obrycki, Dan Potter, Nicole Gauthier, Richard Warner, Tim Woods | August 30, 2016 (New)
The UK Nursery and Landscape Program coordinates the efforts of faculty, staff, and students in several departments within the College of Agriculture tor the benefit of the Kentucky nursery and landscape industry.
PR-707: 2016 Kentucky Small Grains Variety Performance Test
Bill Bruening, Anthony Clark, John Connelly, Blazan Mijatovic, Gene Olson, Sandy Swanson, Dave Sanford | July 1, 2016 (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.
