2019 Long-Term Summary of Kentucky Forage Variety TrialsG.L. Olson, S.R. Smith, J. C. Henning, and C.D. Teutsch, Plant and Soil Sciences

Introduction Forage crops occupy approximately 7 million acres in Kentucky. Forages provide a majority of the nutrition for beef, dairy, horse, goat, sheep, and wild-life in the state. In addition, forage crops play an environmentally friendly 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. 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. Detailed variety reports and forage management publications are available from your local county agent or at the University of Ken-tucky forage website at forages.ca.uky.edu by clicking on the “Forage Variety Trial” link.

Species in this Report 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, green chop, soil improvement, and wildlife habitat. This species is adapted to a wide range of climatic and soil conditions and therefore is versatile as a forage crop. Stands of im-proved varieties are generally productive for two to three years, with the highest yields occurring in the year following establishment. Red clover is used pri-marily as a renovation legume for grass pastures. It is a dominant forage legume in Kentucky because it is relatively easy to establish and has high forage quality and high yield. 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. White clover is classified into ladino, Dutch, and intermediate types. The intermediate types combine the higher yield of ladino with the grazing tolerance of the Dutch types. Alfalfa (Medicago sativa) has histori-cally been the highest yielding, highest quality forage legume grown in Ken-tucky. It forms the basis of Kentucky’s cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets and wildlife habitat. Choos-ing a good alfalfa variety is a key step in establishing a stand of alfalfa. The choice of variety can impact yield, stand persis-tence, insect and disease resistance, and grazing tolerance. 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 higher yields, quality, and long stand life. It produces an open, bunch-type sod, making it very compatible with alfalfa or red clover as a pasture and hay crop or as habitat for wildlife. Tall fescue (Festuca arundinacea) is a productive, well-adapted, persistent, soil-conserving, cool-season grass that is grown on approximately 5.5 million acres in Kentucky. This grass, used for both hay and pasture, is the forage base for most of Kentucky’s livestock enterprises, particularly beef cattle. The predominant variety, KY31, was developed in Kentucky for long-term persistence but contains a fungal endophyte that produces alkaloids detrimental to livestock production and reproductive health. Endophyte-free tall fescue varieties produce no detrimental alkaloids, but UK research shows that they are less persistent than KY31. New novel endophyte tall fescue varieties

contain safe endophytes, which enhance stand persistence but cause no detrimen-tal animal symptoms. 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. Annual ryegrasses (both Italian and Westerwolds type) are increasingly in use across Kentucky as more winter-hardy variet-ies are released and promoted. Annual ryegrass is productive for six to eight months when planted early fall (late August/September) and is used primar-ily for late fall and early to late spring pasture. Perennial ryegrass can be used as a short-lived hay or pasture plant and has growth characteristics similar to tall fescue. It is less persistent than other cool-season grass species. There are both diploid (two sets of chromosomes) and tetraploid (four sets of chromosomes) varieties of perennial ryegrass. Tetra-ploids have larger tillers and seedheads and wider leaves. Tetraploid types tend to be taller and less dense than diploid types, even in early stages of regrowth.

Diploid types produce more tillers, have better stand persistence, and are typically more tolerant to heavy grazing. 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. Timothy is primarily harvested as hay, particularly for horses. In Kentucky, timothy behaves like a short-lived perennial, with stands usually lasting two years. 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 sum-mers. Kentucky bluegrass is best suited for pastures where a dense sod is more important than high-forage production (e.g., horse pastures). Festuloliums are hybrids between vari-ous fescues and ryegrasses with higher quality than tall fescue and improved stand survival over perennial ryegrass. Their use in Kentucky is limited because they do not survive as long as tall fescue. Newer varieties show promise where high quality and yield are more impor-tant than long-term persistence. Bromegrasses have several advantages over tall fescue, including retaining qual-ity as they mature and better growth during dry weather, but they are generally less well adapted in Kentucky. Smooth bromegrass (Bromus inermis Leyss) is a perennial pasture and hay grass native to Europe. It has creeping under-ground stems or rootstocks from which the leafy stems arise. Smooth bromegrass is palatable to all classes of livestock, from emergence to the heading stage. Meadow bromegrass (Bromus biebersteinii Roem. & Schult) is a native of southeastern Europe and the adjacent Near East. It re-sembles smooth bromegrass but has only short rhizomes or none at all. Meadow bromegrass is densely tufted and has a similar growth habit to tall fescue. Hy-brid bromegrasses are a cross between smooth and meadow bromegrasses. Alaska bromegrass (Bromus sitchensis), also called Sitka bromegrass, is a long-lived perennial bunchgrass that will ac-tively grow at moderate rates during the

spring and summer season. It does not spread by rhizomes and is more suited to environments with harsh winters. Prairie bromegrass (Bromus wildenowii) is a tall, cool-season, leafy short-lived, perennial, deep-rooted bunchgrass. It was introduced from South America. Seedheads are produced throughout the growing season, and to maintain produc-tive stands for several years, it is necessary to manage at least one growth cycle each year for seed production and natural reseeding. Some prairie bromegrasses are susceptible to winterkill. Mountain bromegrass (Bromus marginatus) is na-tive to North America from Alaska to northern Mexico, where it can be found in many types of habitat. It is a short-lived, perennial, cool-season, sod-forming grass. Sudangrass (Sorghum bicolor ssp. drummondi) is a rapidly growing annual grass in the sorghum family. It is medium yielding and well suited for grazing or hay because of its smaller stem size. Su-dangrass regrows quickly after harvest and can be grazed several times during summer and early fall. Sorghum-sudangrass hybrids are more vigorous and slightly higher yielding than sudangrass. A larger stem size makes these hybrids less useful for hay; there-fore, they are commonly used for baleage and grazing. Forage sorghum is used primarily as silage for livestock and is typically a one cut crop. It grows 6 to 12 feet tall and is typically harvested when the seed is in the milk to soft dough stage. Pearl millet (Pennisetum glaucum) is the most widely grown type of millet. It is well adapted to production systems characterized by drought, low soil fertil-ity, and high temperature. It is higher yielding than foxtail millet and regrows rapidly after harvest if an 8- to 10-inch stubble height is left. Dwarf varieties, which are leafier and better suited for grazing, are available. The brown midrib or BMR trait is out-ward expression of a genetic mutation in forage sorghum, sorghum-sudangrass, sudangrass, and pearl millet. In most cases, plants possessing the BMR trait contain less or altered lignin, making the plant more digestible and increas-ing animal production. Therefore, it is

desirable to seed summer annuals that have the BMR trait in addition to other desirable characteristics like high yield. With BMR varieties, the midrib of the leaf appears brown or tannish in color. Teff, also referred to as summer love-grass (Eragrostis tef ), is a warm-season annual grass native to Ethiopia and has been used as a grain crop for thousands of years. Recently, there has been consider-able interest in teff as a forage crop. It is high quality, palatable, and fine stemmed and therefore makes excellent hay. Crabgrass (Digitaria sanguinalis) is a warm season annual which propagates by seed. It is adapted to many soil types. Crabgrass can be utilized by either graz-ing or haying and is one of the highest quality warm season forages at a vegeta-tive stage.

Important Selection Considerations Local adaptation and seasonal yield. Choose a variety/species that is adapted to your region of Kentucky, as indicated by good performance across years and locations in replicated yield trials. Also, look for varieties that are productive in the desired season of use. For manage-ment recommendations, check with your county Extension agent or see the forage website at www.uky.edu/Ag/Forage.

the label will include the test date (which must be within the past nine months), the level of germination, and the amount of other crop and weed seed. Order seed well in advance of planting time to assure that it will be available when needed.

Description of the Tests Yield trials. Plots were seeded at the recommended seeding rate per acre and were planted into a prepared seedbed with a disk drill. Plots were 5 feet by 15 feet in a randomized complete block design with four replications. Grass plots were typically fertilized with 60 pounds of actual N per acre in March, after the first cutting, and again in late summer for a total of up to 180 pounds per acre per season. No nitrogen was applied to the legume trials. Other fertilizers (lime, P, and K) were applied as needed accord-ing to the University of Kentucky soil test recommendations. The tests were harvested using a sickle-type forage plot harvester to simulate a spring cut hay/summer grazing/fall stockpile manage-ment system. Fresh weight samples were taken at each harvest to calculate percent dry matter production. Management practices for establishment, fertility, weed control, and harvest timing were in accordance with University of Kentucky recommendations. Grazing trials. Plots were 5 feet by 15 feet in a randomized complete block design, with each variety replicated six times. Plots were seeded at the recom-mended seeding rate per acre and were planted into a prepared seedbed using a disk drill. Grazing was continuous from April to October. Plots were grazed down to below 4 inches quickly and were maintained at 2 to 4 inches (sometimes less) for the remainder of the grazing season. Supplemental hay was fed during periods of slowest growth. Visual ratings of per-cent stand were made in the fall several weeks after the cattle were removed to check stand survival after the grazing season and in the spring prior to grazing to check on winter survival and spring growth. Because trials were seeded in

rows, persistence ratings were based on density within a row and not total ground cover. Grass plots were fertilized with 60 pounds of actual N per acre in the spring and 30 to 40 pounds of actual N in early November after cattle or horses were re-moved from the pasture. Other fertilizers (lime, P, and K) were applied as needed according to the University of Kentucky soil test recommendations. Management practices for establishment, fertility, and weed control were in accordance with University of Kentucky recommenda-tions.

Results and Discussion These tables summarize long-term yield and stand persistence data of com-mercial varieties that have been entered in the University of Kentucky trials. The data are listed as a percentage of the mean of the commercial varieties entered in each specific trial. In other words, the mean for each trial is 100 percent; vari-eties with percentages over 100 yielded better than average, and varieties with percentages less than 100 yielded lower than average. For the grazing trials, vari-eties with percentages over 100 persisted better than average, and varieties with percentages less than 100 persisted less than average. Also in the grazing trials, the alfalfa varieties were compared to Alfagraze, and the fescue varieties were compared to KY31+ instead of the mean of all the commercial varieties. In the horse grazing trials, the fescue varieties were compared to KY31- instead of the mean of all the commercial varieties. Direct, statistical comparisons of variet-ies cannot be made using the summary tables, but these comparisons do help to identify varieties for further consid-eration. Varieties that have performed better than average over many years and at several locations have very stable performance; others may have performed very well in wet years or on particular soil types. These details may influence variety choice, and the information can be found in the yearly reports. See the footnote in each table to determine which yearly report should be referenced.

Summary Selecting a good forage variety is an important first step in establishing a productive stand of forage. 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. For more detailed information on yield and grazing toler-ance within species, go to individual 2019 reports on the forage website. See below for specific reports. The forage website (forages.ca.uky.edu) contains all reports from 2001 through 2019.

Information provided by seed companies.2 Disease resistance: S = susceptible, LR = low resistance, MR = moderate resistance, R = resistance, HR = high resistance. More detailed disease and insect resistance

ratings at www.alfalfa.org/pdf/2019_Alfalfa_Variety_Leaflet.pdf.3 Year trial was established.4 Use this summary table as a guide in making variety decisions, but refer to specific yearly reports to determine statistical differences in forage yield between varieties.

To find actual yields, look in the yearly report for the final year of each specific test. For example, the Princeton trial planted in 2011 was harvested for five years, so the final yield report would be “2015 Alfalfa Report” archived in the UK Forage website at forages.ca.uky.edu.

5 Mean only presented when respective variety was included in two or more trials.6 Number of years of data.

1 Year trial was established.2 Use this summary table as a guide in making variety decisions, but refer to specific yearly reports to determine statistical differences in forage yield between varieties.

To find actual yields, look in the yearly report for the final year of each specific trial. For example, the Lexington trial planted in 2012 was harvested three years, so the final report would be “2015 Timothy and Kentucky Bluegrass Report” archived in the UK Forage website at forages.ca.uky.edu.

1 The festuloliums were in fescue trials from 2001-2005 and in perennial ryegrass trials from 2008-2009.2 MF = meadow fescue, TF = tall fescue, IR = Italian ryegrass, PR = perennial ryegrass, Int = intermediate ryegrass.3 Year trial was established.4 Use this summary table as a guide in making variety decisions, but refer to specific yearly reports to determine statistical differences in forage yield between varieties.

To find actual yields, look in the yearly report for the final year of each specific trial. For example, the Lexington trial planted in 2012 was harvested three years, so the final report would be “2015 Annual and Perennial Ryegrass and Festulolium Report” archived in the UK Forage website at forages.ca.uky.edu.

varieties. To find actual persistence ratings, look in the yearly report for the final year of each specific test. For example, the trial planted in 2010 was grazed for four years so the final persistence report would be “2014 Red and White Clover Grazing Tolerance Report” archived in the UK Forage website at forages.ca.uky.edu.

1 Year trial was established.2 Use this summary table as a guide in making variety decisions, but refer to specific yearly reports to determine statistical differences in stand persistence between

varieties. To find actual persistence ratings, look in the yearly report for the final year of each specific trial. For example, the Lexington trial planted in 2010 was grazed four years so the final report would be “2014 Cool-Season Grass Grazing Tolerance Report” archived in the UK Forage website at forages.ca.uky.edu.

3 Mean only presented when respective variety was included in two or more trials.4 Number of years of data.5 Remington PLUS NEA2 contains a non-toxic (novel) endophyte.6 MF = meadow fescue, PR = perennial ryegrass, IR = Italian ryegrass.
