2019 Timothy and Kentucky Bluegrass Report

3/2/2020 (new)
Authors: Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch

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.

2019 Long-Term Summary of Kentucky Forage Variety Trials

12/18/2019 (new)
Authors: Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch

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 an environmentally friendly role in soil conservation, water quality, and air quality. There are over 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. This publication was developed to provide a user-friendly guide to choosing the best variety for producers based on a summary of forage yield and grazing tolerance trials conducted in Kentucky over the past 12 to 15 years.

2019 Annual Grass Report: Warm Season and Cool Season (Cereals)

12/12/2019 (new)
Authors: Bill Bruening, Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch

Summer annual grasses provide an important forage crop option for producers in Kentucky. These grasses are mainly used as emergency or supplemental hay and pasture crops, but little information is available on their yield potential. The purpose of this publication is to summarize the University of Kentucky 2013-2019 forage yield trials with sudangrass, sorghum/sudangrass, millets, teff, and cereal crops. Cool season annual grasses (specifically cereal crops) are also used as forages crops for hay, baleage or grazing. The cereal crops used in this report are wheat (Triticum aestivum), rye (Secale cereale), oats (Avena sativa) and triticale (Triticum secale).

2019 Cool-Season Grass Grazing Tolerance Report

12/5/2019 (new)
Authors: Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch

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.

2019 Alfalfa Grazing Tolerance Report

12/4/2019 (new)
Authors: Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch

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.

2019 Red and White Clover Grazing Tolerance Report

12/4/2019 (new)
Authors: Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch

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.

Authors: Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch

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.

2019 Annual and Perennial Ryegrass and Festulolium Report

11/27/2019 (new)
Authors: Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch

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. Perennial ryegrass can be used as a short-lived hay or pasture plant and has growth characteristics similar to tall fescue. Festuloliums are hybrids between various fescues and ryegrasses with higher quality than tall fescue and improved stand survival over perennial ryegrass.

2019 Tall Fescue and Bromegrass Report

11/26/2019 (new)
Authors: Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch

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

Warm Season Annual Grasses in Kentucky

3/5/2018 (new)
Authors: Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch

In Kentucky, cool-season grasses produce ample forage in the spring and fall, but high temperatures and short-term drought stress often limits growth during the summer months. Warm-season annual grasses can fill this gap with relatively high quality forage when properly managed. The purpose of this publication is to provide an overview of the various summer annuals for Kentucky.

Baleage: Frequently Asked Questions

3/5/2018 (new)
Authors: Mike Collins, Dennis Hancock, Jimmy Henning, Brandon Sears, Ray Smith, Chris Teutsch

Baled silage, or "baleage", is an excellent method for forage harvest, storage and feed efficiency. Baled silage allows forage to be harvested at higher whole plant moisture levels than required for dry hay. Baleage is ideal for spring cuttings of annual and perennial forages when seasonally frequent rainfall events provide little opportunity for properly curing dry hay. Many producers who want to harvest high quality small grain crops have found baleage to be a good fit for their operation.

Forage Sorghum

2/19/2018 (new)
Authors: Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch

Forage sorghum is the tallest of the summer annuals, reaching 6 to 15 feet in height and is best harvested as silage. Taller varieties produce high forage yield but can lodge, making them difficult to harvest mechanically. Some varieties have been developed that are shorter with increased resistance to lodging. Forage sorghums, like corn, are harvested once per season by direct chopping. While forage sorghum yields are similar to corn, they are lower in energy. The primary advantage of utilizing sorghum for silage production is its greater drought tolerance.

Crabgrass

2/19/2018 (new)
Authors: Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch

Crabgrass possesses significant potential for supplying high quality summer forage although it is considered a weed by many. A primary advantage of crabgrass is that it is well adapted to Kentucky and occurs naturally in most summer pastures, especially those that have been overgrazed. It is also highly palatable and a prolific re-seeder. Planting an improved variety of crabgrass is recommended because the production of naturally-occurring ecotypes varies greatly. Crabgrass is best utilized by grazing.

Authors: Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch

Foxtail millet (German millet) is a fine-stemmed summer annual used mainly for emergency hay or pasture for cattle. It is the lowest yielding of the summer annual grasses since it will not regrow after cutting. It can also be used as a smoother crop when transitioning to other perennial forage crops. Foxtail millet is also commonly used for wildlife plantings to produce food and cover for doves, quail, and other birds.

Sudangrass and Sorghum-sudangrass Hybrids

2/19/2018 (new)
Authors: Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch

Sorghum-sudangrass hybrids are developed by crossing sorghum with true sudangrass. The result is an annual grass that resembles sudangrass, but has coarser stems, taller growth habit, and higher yields. Like sudangrass, hybrids will regrow after grazing if growth is not limited by environmental factors. The coarse stems are difficult to cure as dry hay, therefore these grasses are best utilized for grazing, chopped silage and baleage.

Possible Causes of Yellowing Alfalfa

2/16/2018 (new)
Authors: Chris Teutsch, Paul Vincelli, Kiersten Wise

During spring, several leaf spotting diseases--including Leptosphaerulina (Lepto) leaf spot and spring black stem/leaf spot--are common in alfalfa. Leaf spotting diseases result in distinct round to elongated spots that sometimes have a dark margin. Very wet weather in spring and early summer favor activity of leaf spotting diseases in first and second cuttings. Wet and humid weather during summer favor other leaf spotting and blighting diseases. All leaf spots and blights weaken plants, but alfalfa often outgrows the damage in later cuttings. Maintain a regular cutting schedule, cutting at 30- to 35-day intervals.
