PR-840: 2023 Timothy and Kentucky Bluegrass Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 7, 2023 (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.
PR-841: 2023 Annual and Perennial Ryegrass and Festulolium Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 7, 2023 (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. In Kentucky, winter survival can be an issue for many annual ryegrass varieties, so before planting, review winter survival results in this publication.
PR-831: 2023 Kentucky Small Grains Variety Performance Trial
Bill Bruening, Cam Kenimer, Dalton Mertz, Gene Olson, Phillip Shine, Dave Van Sanford | Jul. 12, 2023 (New)
The objective of the Kentucky small grain variety performance trial is to evaluate varieties of wheat, oat, barley, triticale, and cereal rye that are commercially available or may soon be available to Kentucky farmers. New varieties continually are being developed by agricultural experiment stations and commercial firms. 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.
PR-823: 2022 Cool-Season Grass Grazing Tolerance Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 19, 2022 (New)
Cool-season forages such as tall fescue, orchardgrass, and Kentucky bluegrass are the primary pasture grasses in Kentucky. Other species such as perennial ryegrass and festulolium can also be used in pasture systems. Little is known about the effect of variety on the grazing tolerance of these cool-season grass species.
PR-826: 2022 Long-Term Summary of Kentucky Forage Variety Trials
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 19, 2022 (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 a positive environmental role in soil conservation, water quality, and air quality. There are more than 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.
PR-825: 2022 Annual Grass Report Warm Season and Cool Season (Cereals)
Bill Bruening, Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 19, 2022 (New)
Summer annual grasses provide an important forage crop option for producers in Kentucky. These grasses are mainly used as emergency or supplemental pasture, silage, or hay crops, but little information is available on their yield potential. The purpose of this publication is to summarize the University of Kentucky 2008-2021 forage yield trials with sudangrass, sorghum/sudangrass, forage sorghum, millets, teff, crabgrass, and cereal crops.
PR-822: 2022 Alfalfa, Red Clover and White Clover Grazing Tolerance Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 15, 2022 (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? To answer this question, 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.
PR-824: 2022 Cool-Season Grass Horse Grazing Tolerance Report
Jimmy Henning, Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 14, 2022 (New)
Cool-season forages 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 evaluate varieties of these grasses for persistence when subjected to close, continuous grazing by horses.
