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.
AGR-235: Baleage: Frequently Asked Questions
Jimmy Henning, Brandon Sears, Ray Smith, Chris Teutsch | Dec. 13, 2022 (Minor Revision)
Baled silage, or "baleage," is an excellent method for forage harvest, storage, and feed efficiency. This publication focuses on common questions about baleage. Together with AGR-173: Baling Forage Crops for Silage, this information will help producers better understand the production and use of baleage as livestock feed.
PR-820: 2022 Timothy and Kentucky Bluegrass Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 13, 2022 (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-821: 2022 Annual and Perennial Ryegrass and Festulolium Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 13, 2022 (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.
ID-139: A Comprehensive Guide to Corn Management in Kentucky
Carl Bradley, J.D. Green, John Grove, Greg Halich, Erin Haramoto, Cam Kenimer, Carrie Knott, Chad Lee, Travis Legleiter, Sam McNeill, Michael Montross, Hanna Poffenbarger, Dan Quinn, Edwin Ritchey, Montse Salmeron, Jordan Shockley, Tim Stombaugh, Raul Villanueva, Ole Wendroth, Kiersten Wise | Dec. 13, 2022 (Major Revision)
Corn is a summer annual crop that is grown widely across Kentucky, the United States, and around the world. In the United States, field corn is grown on about 85 million acres (34 million hectares) while sweet corn is grown on about 600,000 acres (240,000 hectares) and popcorn is grown on about 200,000 acres (81,000 hectares). Most of the field corn across the United States is yellow dent corn. In Kentucky, both yellow dent corn and white dent corn are grown. Corn acres in Kentucky peaked at 3.85 million in 1917 and have been around 1.2 to 1.5 million acres since the 1970s (USDA-NASS, 2020). Most corn in Kentucky today is grown in minimum tillage or no-tillage conditions. Most corn acres are rotated with soybean or wheat and double-crop soybeans.
AGR-269: Barn Management for Curing Connecticut Broadleaf Cigar Wrapper Tobacco
Andy Bailey | Dec. 6, 2022 (New)
Connecticut Broadleaf tobacco is used primarily for cigar wrapper and binder and was traditionally grown in Connecticut and Massachusetts but has also been grown in Pennsylvania. In recent years, these areas have not been able to supply leaf buyers with enough wrapper leaf to meet the increasing demand for natural leaf cigar wrapper. Therefore, growers in Tennessee and Kentucky have been producing Connecticut Broadleaf to market as cigar wrapper tobacco.
PR-818: 2022 Orchardgrass Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 6, 2022 (New)
Orchardgrass (Dactylus glomerata) is a high-quality, productive, cool-season grass that is well-adapted 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.
PR-819: 2022 Tall Fescue, Bromegrass and Meadow Fescue Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 6, 2022 (New)
Tall fescue (Festuca arundinacea) 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.
PR-817: 2022 Alfalfa Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 5, 2022 (New)
Alfalfa (Medicago sativa) has historically been the highest-yielding, highest-quality forage legume grown in Kentucky. It is an important part of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets. Choosing a good variety is a key step in establishing a stand of alfalfa. The choice of variety can impact yield, thickness of stand, and persistence.
This report provides yield data on alfalfa varieties included in current yield trials in Kentucky as well as guidelines for selecting alfalfa varieties. Tables 13 and 14 (Roundup Ready varieties) show a summary of all alfalfa varieties tested in Kentucky during the past 18 years. The UK Forage Extension website (https://forages.ca.uky.edu) contains electronic versions of all forage variety testing reports from Kentucky and surrounding states as well as a large number of other forage publications.
