AGR-254: Grain Drill Calibration: Don't Make a Mistake--CALIBRATE!
Jessica Buckman, Chris Teutsch | Dec. 2, 2020 (New)
Grain drill calibration is a critical, yet often ignored part of successful forage establishment and pasture renovation. Planting lower seed rates than recommended can result in thin stands that are susceptible to weed encroachment. Planting more than the recommended seeding rate is undesirable due to increased seed costs. The following calibration method can be applied across a wide range of grain drill types and manufacturers and minimizes the need to carry out detailed mathematical calculations.
ID-262: Considerations for Utilizing Frozen Small Grains for Forage
Carrie Knott, Chris Teutsch, Katherine VanValin | Dec. 2, 2020 (New)
Once wheat and other small grains adapt to cooler weather in the fall, they are relatively tolerant of cold temperatures and freeze injury. Frost injury in the spring normally occurs when February and March are unusually warm and small grains initiate growth earlier than normal or from an unusually late frost event. Freezing temperatures during sensitive growth stages can significantly impact grain yield. In some cases, the impact on yield can be moderate to severe.
AGR-257: Hay Sampling: Strategies for Getting a Good Sample
Jordyn Bush, Jimmy Henning, Tom Keene, Chris Teutsch | Dec. 2, 2020 (New)
Knowing the nutritional quality of forage and hay is an integral part of a profitable and efficient livestock operation. Accurate estimation of forage quality starts with obtaining a representative sample of the forage to be fed. Proper sampling technique is critical. Hay is preserved in different packages ranging from the small square bale weighing 40-50 lb to the large square bale weighing more than 1500 lb. In Kentucky, most hay is packaged in large round bales weighing between 500 and 1500 lb. Wrapped bale silage is also gaining popularity and should be sampled in a similar manner to large round hay bales with the exceptions listed here.
PR-789: 2020 Cool-Season Grass Grazing Tolerance Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 1, 2020 (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 bromegrasses 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.
AGR-252: Soil Sampling Pastures and Hayfields
Chris Teutsch, Edwin Ritchey | Dec. 1, 2020 (New)
Adequate soil fertility in pastures and hayfields is key to maintaining productivity and optimizing profitability. Soil testing is the basis of well-designed fertilization and liming programs. In order to develop effective programs, soil samples must be collected in a manner that results in an accurate representation of each pasture or hayfield area.
PR-784: 2020 Tall Fescue and Bromegrass Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 1, 2020 (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. Much of the tall fescue in Kentuckys infected with an internal fungus (endophyte) that produces ergot alkaloids and results in decreased weight gains in growing ruminants and lower pregnancy rates in breeding stock, especially in hot weather. Varieties are now available that are free of this fungal endophyte or infected with a nontoxic endophyte. Varieties in the latter group are also referred to as "novel" or "friendly" endophyte varieties, because their endophyte improves stand survival without creating animal production problems.
PR-790: 2020 Cool-Season Grass Horse Grazing Tolerance Report
Jimmy Henning, Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 1, 2020 (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-783: 2020 Orchardgrass Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Nov. 24, 2020 (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. This report provides current yield data on orchardgrass varieties included in yield trials in Kentucky as well as guidelines for selecting orchardgrass varieties.
PR-788: 2020 Red and White Clover Grazing Tolerance Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 23, 2020 (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-787: 2020 Alfalfa Grazing Tolerance Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 23, 2020 (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.
