This plant is one of the more dominant species of the tallgrass prairie, but it is found all over North America growing along moist roadsides, streambanks, and woodlands. The plant has deep rhizomatous and fibrous root system nearly as deep as the plant is tall. Switchgrass. Their blades are ascending to widely spreading. The glumes and sterile lemma are ovate, convex along their outer surfaces, longitudinally veined, and narrowly acute at their tips. Due to its potential to spread some wildlife biologists have reduced or eliminated the use of switchgrass in some plantings. Some commonly available ornamental cultivars include: It is up to 8 feet tall in flower, with blue-green leaves selected by Crystal Palace Perennials of Illinois. 0000045948 00000 n There are few definitive comparisons on whether a seedbed prepared using clean tillage or some form of minimum tillage is the better method for establishing switchgrass. The seed provide food for pheasants, quail, turkeys, doves, and songbirds. When ripe, the seeds sometimes take on a pink or dull-purple tinge, and turn golden brown with the foliage of the plant in the fall. The compact plants are only about three feet tall, with taller flower spikes with strong pink tones, and dark burgundy seeds. 0000004617 00000 n An annual cutting in fall or winter suffices for biomass production since its value is based on total tonnage, not nutritional quality.

Burning fields once every 3 to 5 years decreases weed competition, eliminates excessive residue and stimulates switch grass growth. Switchgrass can reduce soil erosion and provide warm season pasture for most ruminants. 0000491272 00000 n Switchgrass. grasses when they are at their nutritional best. 0000002193 00000 n The plant is found growing in black soil prairies, clay prairies, sand prairies, typical savannas, sandy savannas, open woodlands, rocky bluffs, sand dunes, edges of marshes, sandy pannes, banks of rivers and ponds, prairie restorations, areas along railroads, roadsides, ditches, abandoned fields, gravel bars, stream banks, open oak and pine woodlands, shores, riverbanks, and high brackish marshes along maritime forest. Market Value of Switchgrass. perennial. Panicum virgatum, commonly known as switchgrass, is a perennial warm season bunchgrass native to North America, where it occurs naturally from 55°N latitude in Canada southwards into the United States and Mexico.Switchgrass is one of the dominant species of the central North American tallgrass prairie and can be found in remnant prairies, in native grass pastures, and naturalized along roadsides. Switch grass is both a perennial and self-seeding crop, which means farmers do not have to plant and reseed after annual harvesting. Rachis, lateral branches, branchlets, and pedicels are light green (rarely light blue and glaucous), glabrous, and slender. After seedheads emerge, though, nutrient levels decline rapidly and animals refuse to eat much of it. 0000025826 00000 n At a minimum, they will have to pay at least its value as livestock feed, which is expected to be about $95 per ton of DM (equivalent to $83 per ton of 15%-moisture hay). 0000031364 00000 n Terms & conditions This mismanagement weakened the stands and eventually led to their demise. It makes a good substitute for some of the larger Miscanthus cultivars. leaves turn to golden in autumn, Flowers have a well-developed panicle, often up to 60 cm long, and it bears a good crop of seeds, Beautiful reddish-purple seed head atop glossy leaves, 3–6 mm long and up to 1.5 mm wide, and are developed from a single-flowered spikelet, Pink or dull-purple tinge, and turn golden brown with the foliage of the plant, Spermatophytina  (spermatophytes, seed plants, phanérogames), Lilianae  (monocots, monocotyledons, monocotyledons), Panicum virgatum L. var.

Data on switchgrass production on marginal sites are limited. Switchgrass was seeded in 2010 at 30 PLS ft 2 using a no-till drill and seeded at 6-, 12-, 18-, 24-, 30-, and 36-inch row spacings (Figure 1). It is a vigorous, very upright selection by Roy Diblik at Northwind Perennial Farm in Lake Geneva, Wisconsin, growing up to 5 feet tall with steel blue foliage that turns tawny gold in fall, and maroon and green flower plumes held incredibly erect above the foliage. Switchgrass produces high amounts of biomass that can be used for solid biofuel production. Switchgrass cultivars are highly variable, and agronomic research, and perhaps genetic engineering, to develop improved varieties can assist stand establishment, productivity and decrease unwanted nutritional toxins that impact grazing and decrease unwanted combustion products. For hay, switchgrass harvest is recommended at anthesis (around August 1 in eastern Nebraska), but for bioenergy, bedding, or as roughage for feedlot rations, harvest is recommended after a killing frost. 0000000016 00000 n They were replaced by cool-s… Real World Switchgrass is offered in a 10 lb. NUTRITIONAL VALUE : Switchgrass in early growth stages is nutritious. Yields of 2-5 tons per acre can be expect- ed, depending on rainfall and soil type, as well as other environmental conditions. To date switchgrass has been bred primarily to enhance its nutritional value as a forage crop for livestock (Vogel et al. ND-Switchgrass Biomass Yields in the Northern Great Plains (PAVI2) ND-Switchgrass as a Bioenergy Crop (PAVI2) NE-Developing Switchgrass Into a Biomass Fuel Crop (PAVI2) NE-Switchgrass for Grazing and Hay (PAVI2) OH-Ohio State University Seed Biology (PAVI2) OK-Noble Foundation Plant Image Gallery (PAVI2) OK-Oklahoma Forages (PAVI2) Switch grass is excellent forage for cattle; however, it has shown toxicity in horses, sheep, and goats. Switchgrass is often used as hay for cattle as they find it nutritious and palatable. 0000005180 00000 n trailer Switchgrass has so far been bred primarily as a forage crop with a target to enhance its nutritional value [46]. 0000029704 00000 n They are usually medium green (less often light blue and glaucous), hairless to mostly hairless, and either flat or slightly indented along their mid veins. If you are not convinced, take our “Dare to Compare” challenge and plant Real World switchgrass next to other commonly planted switchgrass varieties and see the difference for yourself. Many warm-season perennial grasses were once an important part of the plant community throughout Missouri. Th e objective of this study was to determine the yield, nutritive value, and soil C changes of switch-grass cultivars under grazing and clipping. Before seedheads develop, forage quality is high and palat-ability good. Once established, switch grass stand can survive for ten years or longer. 1991. Switchgrass will benefit from burning of plant residues just prior to initiation of spring growth. Significant differences were also found among 40 switchgrass rust isolates for their germination percentage (p < 0.0001) (data not shown). Based on this, the aim of this study was to evaluate the suitability of switchgrass to Mediterranean environment as forage crop and to improve biomass yield and its nutritional value by intercropping with alfalfa (Medicago sativa L).

Switch grass is excellent forage for cattle; however, it has shown toxicity in horses, sheep, and goats. 53 51 Leaf sheaths are about the same color as the blades and hairless. The company uses a large tub grinder to reduce the grass stems to a consistent length for feeding into the boiler with maximum efficiency. 0000004549 00000 n The effects of defoli-ation management on forage mass, tiller counts, leaf/stem ratio, canopy height, light interception, and weed infesta-tion for ‘Performer’ switchgrass were previously reported by Bekewe et al. Thus, it has been managed primarily as a hay crop for which high leaf to stem ratio and high nutrient content are important. Switchgrass produces large seeds on a spangled-type seed head. Market Value of Switchgrass. Previous research has shown that switchgrass biomass yields respond to nitrogen fertilizer rates of up to 168 kg/ha, depending on ecotype and location (Guretzky, Biermacher, Cook, Kering, & Mosali, 2011; Muir, Sanderson, Ocumpaugh, Jones, & Reed, 2001; Sanderson, Read, & Reed, 1999). https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=40913#null, https://davesgarden.com/guides/pf/go/2634/, https://npgsweb.ars-grin.gov/gringlobal/taxonomydetail.aspx?id=26657, https://pfaf.org/user/Plant.aspx?LatinName=Panicum+virgatum, https://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=l460, https://plants.usda.gov/core/profile?symbol=PAVIV, http://www.theplantlist.org/tpl1.1/record/kew-430831, https://en.wikipedia.org/wiki/Panicum_virgatum, https://www.fs.fed.us/database/feis/plants/graminoid/panvir/all.html. 0000466432 00000 n In the East, it performs well on shallow and droughty soils. defoliation on switchgrass responses. Switchgrass used for wildlife food and cover should be burned once every 3 to 4 years to reduce mulch accumulations that Switchgrass silage benefitted most from addition of alfalfa, urea and plantain. [21] also found that switchgrass production reduced soil erosion and nutrient loss. 0000034593 00000 n Stem is round and can have a red to straw colored tint. 0000042475 00000 n across and 2 inches long. Switchgrass hay, on the other hand, averages less than 15% moisture. Response data of switchgrass to potassium (K) fertilization is limited, especially on low fertility soils, where switchgrass is most likely to be grown for bioenergy purposes. Skype: healthbenefit55. It is more drought tolerant than many cultivars. It is drought tolerant and grows well on shallow rocky soils. Harvesting after frost optimizes nutrient recycling, limits weed problems, and encourages long-term stand persistence. After seedheads emerge, nutrient levels become low and switchgrass becomes less acceptable as pasture.
