Bluegrass We produce quality horse feeds so our customers can reach their potential in their chosen equine discipline. Consequently, tall-growing grasses will thin under abusive management while Kentucky bluegrass volunteers and thickens, providing high-quality forage and protection from soil erosion. And another that is mainly annual ryegrass with some radishes. Kentucky bluegrass (Poa pratensis L.) is a short-to-medium height, cool-season, long-lived, highly palatable, perennial grass that has smooth, soft, green to dark green leaves with boat-shaped tips. The soil must be well drained and medium in texture—Kentucky bluegrass cannot tolerate compacted clay. Calories in Kentucky Fried Chicken based on the calories, fat, protein, carbs and other nutrition information submitted for Kentucky Fried Chicken. All types of fescue have wider blades, thus producing a coarser turf. Warm summer temperatures are the most limiting environmental factor to Kentucky bluegrass production.

Equine nutrition is a Kentucky bluegrass prefers full sun, but will tolerate some shade. Forage and Grazinglands doi: 10.1094/FG‐2011‐1228‐01‐RS. phases of Kentucky bluegrass management. It is an important winter forage grass for these animals in the west. Broadcast seed at a rate of two to three pounds per 1,000 square feet. For best results, the soil pH should be between 6 and 7. COVER VALUE : Kentucky bluegrass provides good cover for small mammals and nongame birds. Exceptions to this trend occur at higher elevations and latitudes where temperatures and rainfall are not limiting. Kentucky Bluegrass Production By John D. Holman and Donn Thill INTRODUCTION The production of Kentucky bluegrass in northern Idaho began during the 1950’s with approximately 10,000 acres and has since grown to 70,000 Kentucky bluegrass pastures often are undergrazed in the spring, which results in an accumulation of mature, low-quality forage. 1 Its first use in the U.S. came as a pasture grass in states like Kentucky, where it still covers the state's gently rolling hills. Pastures composed of Kentucky bluegrass mixed with legumes also have higher nutritional values than pure grass pastures (Table 2). This characteristic makes it more tolerant of overgrazing than most other cool-season grasses. Remember that nitrogen application will increase the grass's competitiveness at the expense of clover and weeds in the stand. Cited by View all 1 citing articles It often reproduces asexually by forming seeds in the ovary wall of the flower. This can be accomplished with frost seeding by seeding into a field with a thin stand of existing plants or where the pasture was grazed "into the ground" the previous fall. Effect of harvest processes on the nutritive value of Kentucky bluegrass residue from seed harvest. To ensure seed germination and seedling survival, water the lawn two or three times a day for the first couple of weeks. It will be most productive in areas of full sunlight, although it can stand some shade if it receives adequate moisture and nutrients. Under normal environmental conditions in Pennsylvania, Kentucky bluegrass achieves nearly 70 percent of its annual forage production by early June. Additional nitrogen applications to pure Kentucky bluegrass stands should be made in late spring and early fall when the grass is growing rapidly. Why do we need this? Usually two to three years are required to produce a good sod from seeding Kentucky Bluegrass Pasture Management Bluegrasses generally grow better in soils of higher fertility and more moisture; when grown in soils not meeting the criteria additional nitrogen has to be added and/or the planting of legumes that co-exist in the pasture with the bluegrass. Tall-growing grasses such as orchardgrass, timothy, smooth bromegrass, or tall fescue also may be included in a pasture seeding mixture with Kentucky bluegrass where hay or silage harvests will be made each year before grazing begins. The tip of the leaf is considered boat-shaped. Always leave a stubble of about two inches to prevent subsequent weed invasion. However, Kentucky bluegrass generally appears in these fields, coming from seed or rhizomes in the soil, particularly if the field was previously a pasture. The rhizomes of bluegrass typically grow two to four inches beneath the surface of the soil, but sometimes deeper. The blades are flat or folded and feel soft to the touch. % Magnes. It provides excellent nutrition to horses, cattle, and sheep when the weather is cool, although its production is limited when the temperatures rise. Palatability/Nutritional Value: Kentucky bluegrass has an average total digestible nutrient (TDN) level of 67% and crude protein level of 12% in the vegetative state. 3 FIGURE 1. Filed Under: The Sunflower State Tagged With: Lawns, Livestock, Nature, Pastures, Plant Health, Soil, Stewardship. Because Kentucky bluegrass grows to a shorter height than many other cool-season forage grasses, it is ideally suited for grazing. In Kentucky tests over 5 years, beef steers gained 1.19 and 1.24 lb/day grazing bluegrass-ladino clover and bluegrass-alfalfa, respectively. Kentucky bluegrass is not a native of the United States, but rather Europe, northern Asia, and some of the mountainous areas of Algeria and Morocco. JavaScript seems to be disabled in your browser. Entering your postal code will help us provide news or event updates for your area. In the fall, the lawn can be core-aerated every year or two to avoid compaction problems. Another plot with 4 different clovers and chicory. The state of Kentucky lays claim to the nickname “Bluegrass State," but Kentucky bluegrass didn't originate there. Maintaining a stubble height of 2 to 4 inches in spring promotes tiller (new shoot) formation, which helps keep a dense sod. Quality declines significantly as … Kentucky bluegrass really excels in climates where the average daily July temperature does not exceed 75 degrees and where the air is humid. Want to use it in a meal plan? Kentucky bluegrass is slightly slower to establish than many other cool-season grasses. Press wheels or cultipacking used in conjunction with or after band seeding will improve the seed-soil contact and the chances of obtaining a good stand. The panicle is 1-1/2 to 5 inches long and 1 to 3 inches wide. The waving branches bear spikelets on their ends. Adult Japanese beetle, May beetle, green June beetle, northern masked chafer, and European chafer lay eggs in thin, overgrazed bluegrass pastures, and the larvae then feed on bluegrass roots and rhizomes. View our privacy policy. Kentucky bluegrass-white clover pastures can be maintained indefinitely and their forage quality improved by applying lime and fertilizers according to soil test recommendations. Average annual liveweight gains for the two systems were 446 and 536 lb/A. If the soil test calls for large amounts of nutrients, they should be applied prior to seeding and incorporated into the seedbed. Very few fields in the Northeast are sown with Kentucky bluegrass seed. Delaying seeding until mid-morning when the soil has become slippery on the surface will result in poorer stand establishment. It can be seeded as a monoculture, but mixing it with a legume will increase its nutritional value still further and provide for the nitrogen needs of the grass stand, as well. The forage value of Kentucky bluegrass is well known across the nation. Kentucky Bluegrass grows best on heavier soils with a pH above 6. It takes off quickly in early spring and grows aggressively while the weather is cool, starting from the previous year’s roots and continuing with a fresh new crop of roots. Calories, carbs, fat, protein, fiber, cholesterol, and more for Kentucky, Bluegrass , regular (Smashburger). Higher seeding rates ensure quicker ground cover. Late in the fall, the growth slows down and carbohydrates are stored in the abundance of new rhizomes to provide the nutrients needed to start all over again in the spring. Parts of a Grass Plant: A Glossary Kentucky bluegrass is capable of forming dense mats thanks to its abundant rhizomes, tough stems that grow horizontally under the ground. You must have JavaScript enabled in your browser to utilize the functionality of this website. Salinity: Kentucky bluegrass is sensitive to salinity (Lunt et al. These effects are particularly damaging to Kentucky bluegrass in a dry summer when it is less able to recover. Kentucky bluegrass is susceptible to many of the same diseases as other cool-season forage grasses. As Kentucky bluegrass abundance increases, rangeland forage production shifts to an earlier … Kentucky bluegrass productivity is increased substantially with proper pasture rotation and rest. Surface application of the recommended nutrients is equally beneficial if the Kentucky bluegrass is already established. Grubs cause the most serious damage to Kentucky bluegrass pastures. In addition, the dense sod formed by Kentucky bluegrass rhizomes make it ideal for erosion control, particularly in grass waterways. Kentucky bluegrass can be "frost seeded" (in early spring when the soil is still honeycombed with frost) into existing pastures to thicken the stand. Other forages The forage value of Kentucky bluegrass is well known across the nation. This grass species is slower to germinate than most cool season grasses, taking at 7 to 21 days. Applying approximately 25 pounds per acre of nitrogen fertilizer to Kentucky bluegrass in early spring before green-up will stimulate growth and generally allow grazing to begin earlier. 1992, Alshammary et al This ability makes Kentucky bluegrass an ideal species for permanent pastures that are continuously grazed. Reduce the stocking density later in the grazing season as grass growth slows. Highly desired for its strong rhizomatous growth habit and unmistakable turf quality, Kentucky bluegrass is an extremely varied species. Its growth slows during the warm summer months. Each spikelet has three to six flowers capable of producing abundant awnless seed. Although Kentucky bluegrass is found throughout the United States, it is most important agriculturally in the north central and northeastern regions and is best adapted to areas where the average daily temperature during July does not exceed 75°F. Therefore, you should cultipack the seedbed before seeding. Kentucky bluegrass. Its pH preference is 6.0 to 7.0. Guinea Lynx' HAY CHART All Hay Sun-cured Values in % or Ratio Dry Matter % Crude Protein % Calcium % Phosph. Quality and palatability declines when Kentucky bluegrass matures. Kentucky bluegrass's nitrogen requirements and low summer production make it ideal for seeding with a legume such as white clover at 4 pounds per acre, red clover at 6 pounds per acre, or birdsfoot trefoil at 8 pounds per acre. Despite its adaptation to this wide range of locations, bluegrass is actually rather specific in its preferences and will not truly thrive unless its needs are met. Mow whenever the grass reaches three inches tall to bring it back down to a height of two inches (never lower than this, or the plants will be damaged and become more susceptible to disease). See All Pest, Disease and Weed Identification, See All Beer, Hard Cider, and Distilled Spirits, See All Community Planning and Engagement. Seeding Kentucky bluegrass alone or in a mixture into a conventionally prepared seedbed or no-till seeding can also be an excellent method of establishment. Palatability/Nutritional Value: In the vegetative stage, Kentucky bluegrass has 12% protein and a digestibility (Total Digestible Nutrient) composition of 67%. In Kansas, the best time to plant is September, as the soil will be cooling off and the weeds will be less competitive than in the spring. These studies indicated that the nutritive value of brome–fescue hay was highest, followed by Kentucky bluegrass and sedge hays, and then oat straw. The type and amount of maintenance bluegrass will require in this role will depend on the specific application. SITMMARY A 3-year study was made to determine the nutritional value of four grasses-- Lincoln bromegrass, orchard grass, Kentncky 31 fescue, and Kentucky bluegrass for lactating dairy cows. 1975, Harivandi et al. Successful seeding requires good seed-to-soil contact. Generally, turf clippings contain 6-7% nitrogen, 0.5 to 1.0% phosphorous and 2-4% potassium; when returned to the lawn, they can account for a fourth of the lawn's fertilizer applications each year. Kentucky bluegrass has a large proportion of its leaves close to the soil surface and below the grazing height in managed pastures. Once the stand is established, it can be grazed in the early spring as soon as the grass reaches five inches tall. Poa pratensis, commonly known as Kentucky bluegrass (or blue grass), smooth meadow-grass, or common meadow-grass, is a perennial species of grass native to practically all of Europe, North Asia and the mountains of Algeria and Morocco. Therefore, it is widely considered to be the most important lawn grass in the United States. Nutritional Value for the Landscape Processing lawn clippings and tree leaves into the lawn provides nutritional value as well as reduces waste. In pastures, grazing should begin when grass is about 5 inches tall and should not be grazed shorter than 1-1/2 to 2 inches. Kentucky bluegrass flowers from May through July. Do not plant deeper than ¼ inch when seeding. SWIFT RW, COWAN RL, INGRAM RH, MADDY HK, BARRON GP, GROSE EC, … Each leaf arises from a sheath with large veins. Kentucky Bluegrass, Poa pratensis L. Tom Cook Oregon State University Introduction: Kentucky bluegrass has long been the most important cool season grass planted as turf. Its seeds feed many different songbirds and rodents. However, once established it spreads quickly via its extensive rhizome production. Kentucky bluegrass is a strong turf component commonly used across the temperate and cooler climates of the U.S. If the amount of white clover in the pasture is too great, then allowing the pasture to reach a height of 8 to 12 inches will encourage the Kentucky bluegrass to compete better with the white clover. Consequently, proper management during the early growing season is essential to maximize production potential. Kentucky bluegrass also forms a tight sod, providing good pasture footing.
