PR-808: 2021 Cool-Season Grass Horse Grazing Tolerance Report
Jimmy Henning, Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 7, 2021 (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. 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 growing season. The main focus will be on stand survival but data on seedling vigor and grazing preference are also included
PR-805: 2021 Alfalfa Grazing Tolerance Report
Joao Costa, Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 3, 2021 (New)
This report summarizes research on the grazing tolerance of alfalfa varieties when subjected to continuous heavy grazing pressure during the grazing season. A summary of all alfalfa varieties tested in Kentucky during the last 20 years and information about distributors, fall dormancy ratings, and disease resistance is included at the end of this report.
PR-802: 2021 Tall Fescue, Bromegrass, and Meadow Fescue Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 2, 2021 (New)
Selecting a good variety of tall fescue and bromegrass is an important first step in establishing a productive stand of grass. Proper management, beginning with seedbed preparation and continuing throughout the life of the stand, is necessary for even the highest-yielding variety to produce to its genetic potential.
PR-806: 2021 Red and White Clover Grazing Tolerance Report
Joao Costa, Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 2, 2021 (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, soil improvement, and wildlife habitat. This species is adapted to a wide range of climatic and soil conditions. 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.
PR-803: 2021 Timothy and Kentucky Bluegrass Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Nov. 30, 2021 (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. Kentucky bluegrass (Poa pratensis) is a high-quality, highly palatable, long-lived pasture plant with limited use for hay. It tolerates close, frequent grazing better than most grasses. It has low yields and low summer production and becomes dormant and brown during hot, dry summers. Kentucky bluegrass is slow to establish.
PR-812: 2021 Kentucky Hybrid Corn Performance Test
Cam Kenimer, Chad Lee, Phillip Shine | Nov. 28, 2021 (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. The hybrids submitted for testing are those most likely to be available for sale in 2022.
PR-800: 2021 Red and White Clover Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 23, 2021 (New)
Red clover (Trifolium pratense L.) is a high-quality, short-lived, perennial legume 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 generally are productive for 2-1/2 to 3 years, with the highest yields occurring in the year following establishment. Red clover is used primarily as a renovation legume for grass pastures and hay fields. It is a dominant forage legume in Kentucky because it is relatively easy to establish and has high forage quality, yield, and animal acceptance.
PR-804: 2021 Annual and Perennial Ryegrass and Festulolium Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 23, 2021 (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-811: 2021 Kentucky Soybean Performance Tests
Dalton Mertz, Claire Venard | Nov. 18, 2021 (New)
The Kentucky Soybean Variety Performance Tests are conducted to provide an unbiased and objective estimate of the relative performance of soybean varieties commercially available in Kentucky. This information may be used by growers and seed producers to aid in selecting varieties that will give the highest total production in a specific situation. Soybean cultivars in the 2021 tests were entered by soybean growers, commercial companies, state and federal institutions.
4AH-10PO: Windowsill Garden Project
Bill Fountain, Dick LeMaster, Ashley Osborne | Nov. 18, 2021 (New)
This guide is for volunteer leaders or county Extension personnel, and includes four lessons designed for youth in 3rd‐5th grades. Each lesson focuses on an aspect of seeds, plants, and/or gardening. Three additional experiments are included in the Digging Deeper section that youth can do independently or in a group or classroom setting. At the end of the guide, additional resources and an appendix are available. The National 4‐H Gardening Series, which includes 4 levels for grades 3rd‐12th and a Helper's Guide, is recommended if additional background information is needed. The National 4‐H Gardening Series includes projects and activities for youth that have an interest in continuing to learn more about plant science and gardening after completing their windowsill garden.
