Red clover in a corn>soybean>wheat/red clover rotation in a reduced-input system out-performed continuous corn in a four-year Wisconsin study. Koger, M., W.G. ‘Osceola’, developed in Florida, retains the large type growth habit, but has increased flowering and has been a successful cultivar throughout the southeast USA for much of the1990s (Baltensperger, et al., 1984). Bouton. The focus will be on the two major perennial clover species, red (T. pratense L.) and white (T. repens L.) clover, with some attention to crimson (T. incarnatum L.), and less emphasis on arrowleaf (T. vesiculosum Savi. Hoveland, C.S., D.R. The change in emphasis of the USDA-ARS program at Mississippi also resulted in a significant reduction in research with crimson clover in the region. Crimson Clover: Yes: No: No ... For more information, check out Cover Crop Termination fact sheet. 740. ‘Osceola’ white clover. The selling price of high quality legume hay is generally most influenced by supply and demand and also by purchaser preferences. Dunavin, and R. L. Stanley. Crimson clover's primary advantages are rapid growth during cool weather, shade tolerance and a positive reseeding potential. The genus includes approximately 230 species found naturally on all the world’s continents except Australia, although several have been naturalized there. Taylor, N.L., and K.H. Dordrecht, Netherlands. Hard-seeded varieties (including Chief and Dixie) will wait until fall to germinate if seed is set in late spring. 72:581-584. Proc. Recent white clover research at Florida has focused on selection for RKN resistance in an Osceola type. Decreased weed pressure, especially in spring and fall 4. The problem with the clovers appears to be that of identifying a company that has good seed production and processing capabilities in the Pacific Northwest and a strong and diverse sales, advertising and marketing organization in the Southeast. Forage legume breeeding and evaluation at Auburn University in the last 16 years. The leaflets of red clover are oval-shaped and most are marked with a white “V.” Red clover is widely adapted to different soil and climatic conditions and is fairly tolerant of soil acidity. Medium red clover prefers cool weather conditions. If broadcasting crimson seed, disk it lightly to incorporate. Crimson Clover Information. Inoculate the seed with Rhizobium inoculant for true clovers when planting in a field in which a nodulated true clover has not been grown in the last three years. 1989. in production and marketing. Managing Cover Crops Profitably explores how and why cover crops work, and provides all the information needed to build cover crops into any farming operation. The Kentucky program has recently released ‘Freedom!’, a red clover that has no pubescence (non-glandular trichomes or hairs), and was developed to permit faster drying and to reduce dustiness of hay. Red clover is a short-lived perennial that is winter hardy throughout Pennsylvania. 25:101-105. Increased soil organic matter and decreased soil erosion and surface water pollution 3. Crimson clover does best in heavy, well-drained soils and is widely grown in North and Northwest Florida. Dinitrogen fixation, and N and dry matter distribution during 4-year stands of birdsfoot trefoil and red clover. Cover Crop Interseeder – Potential for Injury from Corn Herbicides, Penn State Extension Cover crops: annual ryegrass, red clover, mix 1990. Steer performance on perennial vs. winter annual pastures in north Georgia. Its use began as early as the mid 1800s and interest in using it increased around 1940. It is also evident that substantial research is available to document the value of clovers for various applications. By: Christina Curell, Michigan State University Extension. Planning for cover crops after winter wheat. 3: 100-102. Crimson clover is an excellent producer of nitrogen and there are some newer varieties on the market that are very winterhardy even into Michigan.Dr. Quesenberry, K.H., D.D. Flame crimson clover. Like other clovers, crimson clover fixes nitrogen, but it's faster growing for quick benefits to your garden. Crimson Clover. Its ability to handle both shade and heat make it ideal for this. Crimson clover has proved to be more promising in this niche than black medic, red clover or annual ryegrass, averaging 1,500 lb. Crimson clover flowers are more elongated, almost coming to a point, and they are deep dark red. Traditionally used further south, MSU researchers and southern Michigan farmers have used this annual clover effectively as a cover crop in corn, soybeans and wheat. The legume cover crop system used no commercial fertilizer, no insecticides and herbicides on only two occasions—once to-spot spray Canada thistles and once as a rescue treatment for soybeans. Barnes, C.P. Crimson clover does two great things as a cover crop. N/A. J. In this case, 15 lb/A of crimson seed is sufficient, along with 1.5 to 2 bu/A of a cereal (oats, barley, wheat), or 18-25 lb/A of annual ryegrass seed. Crimson clover (Trifolium incarnatum) is native to the Mediterranean region. Stn. Topics: cover crop species selection for use in mixes, seeding rates Cover crops: mixes. Baltensperger, D. D., G. M. Prine, K. A. Albrecht, L.S. p.11. This information is for educational purposes only. For example, the cultivar ‘Marathon’, bred at Madison, Wisconsin (Smith, 1994) is generally among the poorest yielding when grown at Gainesville, Florida. In Proc XVI Trifolium Conference. Hardin, P.C. The Texas program has selected for late flowering and has a potential cultivar in testing for release. Dry matter yield estimates for red and white clover are variable depending on many factors including cultivar, location, and weather pattern in a given year. The clover is not hardy in the Northern part and does not bloom earlier like most other clovers. The flowers are 2 inches long and bright red, while leaves are dark green. Dunavin, W. R. Ocumpaugh, and P. Mislevy. Prine, O.C. 1996. AgriLife Extension's online Bookstore offers educational information and resources related to our many areas of expertise and programming; from agriculture, horticulture, and natural resources to nutrition, wellness for families and youth, and much more. Crop Sci. Red, White, Crimson, and Other Southern Clovers: The true clovers are members of the genus Trifolium, one of the most important genera in the legume family. Dr, G. R. Smith indicates that a new arrowleaf clover cultivar, ‘Apache’, with better resistance to bean yellow mosaic virus (BYMV) disease and higher forage yields than ‘Yuchi’ has been released. Crimson clover can be killed by moldboard plowing or with herbicides (see Controlling Cover Crops in Michigan information sheet). Avoid using it on poorly drained soils, however, due to potential disease problems. Sometimes the use of clover can be viewed as an increased cost with associated risk. Seed of Apache should be available to producers in fall 2002. This paper will attempt to summarize the current status of cultivars and cultivar improvement efforts in the USA Southern Region and discuss some of the factors contributing to the current status. White Clover. Univ. Proc. Productivity and quality of annual and perennial clover-tall fescue mixtures. Stn. Steer performance on tall fescue pastures. 40:290. Myers, N. Gammon, Jr., A.C. Warnick, and J.C. Crockett. Other extensive research has documented that inclusion of clover in the sward of endophyte infected fescue pastures will ameliorate the toxic effect of the ergovaline alkaloids produced by the endophyte (McMurphy, et al., 1990). Having documented the value of clovers, however, the use of clovers must be weighed against alternatives for providing the need addressed in each of the above categories. 1994. Lusby, S.C. Smith, S.H. The primary disadvantages to crimson clover are the seed cost and potential for winter kill, although both of these challenges may change in the near future as new varieties are developed. Petritz, D.C., V.L. 1985. For example, the value of a clover crop for biological N2-fixation to add N to the soil for a companion grass or in crop rotations for a grain crop, must be weighed against the use of commercial N fertilizer for these same purposes. Those varieties with a large proportion of hard seed are ideal for self-reseeding, which is often desired in orchards. Use as a forage or pasture species Baltensperger, D.D., C.E. Crimson leaves have a more rounded tip and both stem and leaves have more hair than red clover. Most state agricultural experiment stations are currently willing to enter into exclusive licensing and production agreements for cultivars today. It must be noted, though, that a crimson clover stand that is winter killed will probably release much of its nitrogen prior to maximum uptake by the succeeding corn crop. Fla. Ag. Kluwer Academic Publishers. Legumes such as crimson clover, ladino white clover, red clover, hairy vetch and winter pea do not generally produce as cover crops, rather than the large-seeded varieties grown primarily as a food crop. Red clover. Selection for reduced winter dormancy response has improved the production potential of red clover in the lower south. The current low level of use of clovers would suggest that farmers in the southeast USA have determined that economics often favor alternatives to growing clovers. Estimates of the amount of N fixed by perennial clovers are in the range of 100 to 300 kg ha-1 yr-1. 1987. A wide range of clover species available developed specifically for cover crops including berseem clover, crimson, red, white, and Persian clover. Research at Texas has focused on development of an early flowering white clover (replacement for La S-1). 1980. Crop Sci. Spring oats are very quick to establish and do an excellent job of suppressing weeds as the main cover crop becomes established. 2000. Barnes, D.A. Plant at a rate of 12-20 lbs/A, using the lower rate in cool soils and the higher rate in warmer soils. Mosjidis, J. Agric. At Florida, five cycles for production and vigor on well drained sandy soils with high disease and nematode pressure have been conducted. Crimson clover is a real jewel among the cover crop species. Exp. and ball (T. nigrescens Viv.) In R.F. Crimson clover also comes in hard-seeded and soft-seeded varieties. As with all cover crops, killing time for crimson clover is determined by the planting date for the succeeding crop and/or soil moisture. Mosjidis, J. Prod. Also called incarnate clover because of their blood-red blooms, crimson clover has been used as a cover crop in the United States since the mid-1800s. Current prices of N in the form of NH4NO3 are in the range of $225 to 250 t-1 or about $0.34 to 0.38 lb-1 N. Assuming an intermediate level of N2-fixation of 150 lb acre-1 yr-1 and a cost of $0.35 lb-1 N, the value of N fixed annually by the estimated 10 million acres of red clover in the United States would be $525 million. A unique education agency, the Texas A&M AgriLife Extension Service teaches Texans wherever they live, extending research-based knowledge to benefit their families and communities. Jeffrey W. Dwyer, Director, MSU Extension, East Lansing, MI 48824. Crimson clover (Trifolium incarnatum) is frequently seen along roadsides where it is planted for highway beautification, but it can be used in your garden as well. Miller, and C.J. Crimson seed should be planted at a depth of 0.25- to 0.5-inch. Circular S-231. Nitrogen fixation. The change in emphasis of the USDA-ARS program at Mississippi during the 1990s resulted in a significant reduction in research with white clover in the region. Do not confuse this plant with the perennial red clover. Crush, J.R. 1987. Click for a hub of Extension resources related to the current COVID-19 situation. Red clover has a life cycle of 2-3 years, by which time you may want to rotate your crops anyway. Registration of ‘Marathon” red clover. Vance, and K.I. As an example, red clover was estimated to be planted on as much as 35 million acres in the period 1909 to 1920, but declined to around 15 million acres in 1957, and to an estimated 10 million acres in 1995 (Taylor and Quesenberry, 1996). Bill Deen has been researching the link between cover crops and soil health since joining the University of Guelph in 2000, where he inherited long-term data that now dates back more than 30 … clover. The question then becomes, why aren’t producers utilizing these plants to a greater extent. Florida Agric. Nitrogen credit for succeeding crops (average of at least 30 to 60 lbs/A for fall-planted, spring-killed stands in Michigan) 2. CAB International, Wallingford, UK. Agron. Red clover and crimson clover don’t look anything alike. Southern Pasture & Forage Crop Improvement Conference. J. Production response and economic returns from five pasture programs in north central Florida. Ruelke, L.S. Iowa State University Press, Ames IA. DM/A and more than 50 lb. Over the past 60 years, many different types of crimson clover have been produced. Clovers for Nitrogen Fixation. Heichel, G.H., D.K. Smith. Sources: Kellogg Biological Station Cover Crops Research Program; Northeast Cover Crop Handbook, Marianne Sarrantonio, 1994, Rodale Institute; Managing Cover Crops Profitably, Sustainable Agriculture Research and Education Program, USDA. Clovers are rapid growing biennials or short-lived perennials. In a dry spring, kill the cover early to avoid water stress on the succeeding crop. Conversely, although Cherokee may yield well in the seeding year in Kentucky it does not go dormant in the fall early enough and may initiate regrowth too soon in the spring resulting in winter killing and poor yields in the second year. Crimson clover has taller flower stems, grows more quickly and has larger seeds than the more commonly used red clover. Medium Red Clover – Cover Crop April 1, 2011 by SoilGuide Leave a Comment If you are faced with depleted soil and have a season or two to enrich the soil before your desired planing, one of the best cover crops or green manures to introduce to your property is medium red clover. Quesenberry, K.H., G.M. Crop Sci. Depending on one’s classification, only about 8 to 14 species are of significant use as sown pasture crops around the world. Crimson clover has many benefits when used at a cover crop for the farm system. DM/A by July, adding 80 lb. With the potential to produce 100 + lbs. of nitrogen, it is a nice addition to mixes. Lechtenberg, and W.H. P. 217-226. Red clover is also good for weed suppression. Red clover is not only the most widely used clover as a cover crop, but it is also one of the most widely used as a cover. Crimson clover … MSU is an affirmative-action, equal-opportunity employer. Fla. Ag. A., C. M. Owsley, M. S. Kirkland, and K. M. Rogers. The effects of enhanced crude protein content of the animal diet provided by the inclusion of clovers in a grass-clover grazed pasture are well known. It forms tap roots and is useful for remediation of compacted soils. Williams (ed.) Research programs working with white clover in the southeast USA are currently located at Florida, Georgia, and Texas. Wilcox, and S.R. 1970. Crimson clover (Trifolium incarnatum) is a relatively new cover crop for Michigan. It has been used for a cover crop as far North as northern Maine. No research is known to have been conducted with this species in the SE USA in recent years. For this reason, clover is an ideal candidate for cover crop programs in many situations. In this case it is which comes first, the demand for clovers or the production and marketing of new cultivars of clovers. of Florida, Gainesville. Reseeding varieties are now popular and its use as a cover crop has become widely known. Henjum. Major red clover breeding programs in the southeast USA since the 1980s have been located in Kentucky and Florida, although more recently work is being conducted in Georgia and Alabama. Clovers for Hay. • Red clover (Trifolium pretense) (Figure 7) is a short-lived perennial cover crop, but it is sometimes used in annual crop rotations when there is a longer win-dow for cover cropping. From the perspective of the breeders that I talk to, a major point of potential failure of new cultivars occurs after release, ie. Nutrient release from crimson clover residue— and that of other winter annual legumes—is quicker if the cover crop is tilled lightly into the soil. Seed germination and seedling survival require cool, but not cold, night temperatures (less than 60"F) and sufficient soil moisture. Exp. Thus, crimson clover can be planted early in spring or fall for weed control, or overseeded in corn at second cultivation or in soybeans at leaf drop. Crimson clover is a top nitrogen producer and beautiful as well. Smith. When used as a cover crop or green manure, decomposing clover adds large amounts of organic matter to the soil. 1991. Ball Clover. The intermediate types are typical of many pasture ecotypes with abundant flowering in spring, shorter growth habit, and a higher stolon density than large types. N/A for fall vegetables. Crimson clover's many benefits include: 1. The clover is an annual bloom and you must plant it each year to enjoy the best yield. Root-knot nematodes have been identified as limiting factors to clover production on the sandy soils of the lower Coastal Planins of the southeast USA. Agron. The Alabama program, which was recently summarized in these proceedings (Mosjidis, 2001), has released an early maturing type, ‘AU Sunrise’ (Mosjidis, et al., 2000). 1984. J. Crimson clover. sods. Planting crimson with a grass can help prevent some winter kill. produced by the cover crop inhibit growth of other plants. Many confuse red clover with crimson clover, which produces red/crimson flowers. In the southeast USA [Zone B (Taylor and Smith, 1995)] successful operators have used red clover in combination with crimson clover (T. incarnatum L.) and annual ryegrass (Lolium multiflorum Lam.) I believe that the answer to this lies in the classic chicken vs. egg debate! Red clover is the number one choice of legumes when considering spring interseeding. The Georgia program has shown that intermediate ecotypes selected from long term grazed pastures have higher stolon density and are much more persistent in grazed swards than either the current large type cultivars or presently available intermediate cultivars (Hoveland and Bouton, 2000). Buy clover seeds online, all with nationwide delivery. Nelson (ed) Forages Volume 1: An introduction to grassland agriculture. It was developed from Yuchi, ‘Meechee’, and ‘Amclo’ germplasm through restricted recurrent phenotypic selection for tolerance to BYMV. Pederson, G.A., and G.E. For example, Osceola has been successfully grown in most white clover growing areas of the USA, well north of its latitude of development. Selection for root-knot tolerance in red clover. 57th Southern Pasture and Forage Crop Improvement Conference, Athens, GA April 23-25, 2002. Along with detailed management information on the most commonly used species—including grasses, grains, brassicas and mustards, and legumes—Managing Cover Crops Profitably offers chapters on the role of cover crops in […] Today, it is the most common legume cover crop and forage Intermediate types are generally less winter dormant, and thus flower earlier and more profusely than large types. Taylor, N.L., and R.R. Assuming yields of 8,000 lbs acre-1 and a selling price of $160 ton-1 for good quality red clover hay, the value of hay if all the 10 million USA acres of red clover were harvested for hay could be as high as $6.4 billion. Strasia. Because of its shade tolerance and reseeding potential, crimson is also effective as a living cover in orchards. Muntz and C.A. Clover, also known as Trifolium, is a common genus of plant that can be found all across the United States. Persistence of selected white clovers in closely grazed tall fescue and bermudagrass sods. Since red clover seedlings tend to be slow growing, it benefits from a nurse crop. Major Perennial Clovers: Who Is Doing What in the SE USA? Arrowleaf clover. Registration of ‘Cherokee’ red clover. Crimson clover can tolerate almost any soil type, but prefers loam soils with good drainage. Red Clover. New cultivars can flounder and fail for lack of either production or marketing. As with many cover crops, crimson clover seed germinates better and requires lower seeding rates when drilled than when broadcast. Crimson plants have dark green leaves and grow to a height of 1-3 feet. Both red and white clover are perennial legumes high in protein and fiber that are widely used as forage for animal grazing and pastures. Crop Sci. Also, the plants listed were sent in by readers from their various regions and compiled. Performance and economic returns of beef cows and calves grazing grass-legume herbage. Red Clover. Apart from erosion concerns, this fertility enhancing step adds cost and decreases the weed-suppression effect early in the subsequent Worley. 4:24-28. Clover acts as a natural mulch to protect your soil. Crimson clover was first used in the U.S. in the south as a pasture legume. ... Avoid clover competition when frost seeding medium red clover into winter wheat. In addition, winter kill may be beneficial because it leaves a field ready for spring work. Clover also adds nutrients to your soil, and reduces your need for fertilizers. Smith, R.R. For example, red clover is a Crimson clover grows best in cool weather, so grow it as a spring or fall cover crop. ), rose (T. hirtum All.) Bull. Registration of ‘AU Sunrise’ crimson clover. Clover fixes nitrogen in the soil and is great for adding fertility to your soil. There are two principal types of white clover grown in commercial agriculture, intermediate types, sometimes called Dutch white clover, and the large types, sometimes called Ladino white clover or Ladino clover. Typical yields in the USA are in the range of 6,000 to 9,000 lbs acre-1(Pederson and Brink, 1991). This annual clover has larger, elongated flower heads with deep red, long-lasting blossoms that invite beneficial insects, such as ladybugs and bees. In contrast to red clover, the dormancy response of white clover does not seem to be as great a factor in stand persistence, although, as previously mentioned, it does influence flowering density and subsequent reseeding potential. Crop Sci. Hoveland, C.S., and J.H. Michigan State University Extension programs and materials are open to all without regard to race, color, national origin, gender, gender identity, religion, age, height, weight, disability, political beliefs, sexual orientation, marital status, family status or veteran status. There is a feeling among breeders that aggressive marketing is needed to cultivate the demand for new cultivars, but the culture of “buy the cheapest seed available”, usually does not reward the those who are willing to invest in advertising. They are typically planted with companion grasses and used as a cover crop during crop rotation, particularly organic crops. Benefits to beef cattle accrue in both improved calving percentage (Koger, et al., 1970) and improved weight gain of growing calves (Petritz, et al., 1980). Killinger, R.E.L. In Maine, spring-seeded crimson clover can yield 4,000 to 5,000 lb. The 4-H Name and Emblem have special protections from Congress, protected by code 18 USC 707. A long term reseeding population was collected in north Florida in 2000 and 2001, and preliminary evaluations are underway to identify superior plants in this population for potential development of an improved cultivar.
