Expanding on that theme, let's examine switchgrass forage yields and quality over a growing season when the crop is properly managed. Both glumes are present and well developed. The ideal switchgrass wouldn’t possess one trait, but many. 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). Switchgrass silage benefitted most from addition of alfalfa, urea and plantain. Switch grass uses C4 carbon fixation, giving it an advantage in conditions of drought and high temperature. They are open at their apices, forming a V-shape. King et al. Borhidi, Panicum virgatum var. Real World Switchgrass is offered in a 10 lb. yield and its nutritional value by intercropping with alfalfa (Medicago sativaL). Isolate NC01 had the highest germination rate with 99.95% and MS0911 had the lowest with 96.73% (data not shown). Skype: healthbenefit55. 53 51 xref May flop in overly rich soils, About 2.7 m (8 ft. 10 in) high, but is typically shorter than big bluestem grass or Indian grass, Deep rhizomatous and fibrous root system nearly as deep as the plant is tall, Light to medium green (less often light blue and glaucous), terete, glabrous, and fairly stout, Round and can have a red to straw colored tint, 30–90 cm (12–35 in) long, with a prominent midrib. 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. After seedheads emerge, though, nutrient levels decline rapidly and animals refuse to eat much of it. Vogel, 1995). It provides good warm-season pasture and high quality hay for livestock. Ani-mals are reluctant to eat mature switchgrass and may refuse it entirely if other feed is available. Switchgrass may have value for stockers because of its early spring availability, high yields, perennial life form, wide adaptability and low fertilization requirements. [21] also found that switchgrass production reduced soil erosion and nutrient loss. Switchgrass does well on a wide variety of soil types. © 2020 Healthbenefitstimes. scorteum H.P.Linder, Panicum virgatum var. After seedheads emerge, however, nutritive value declines rapidly, and the plant provides only the minimum maintenance energy needs of ruminants [ 35 ]. Several alternate leaves occur along the entire length of each culm. Yields of 2-5 tons per acre can be expect- ed, depending on rainfall and soil type, as well as other environmental conditions. 0000041883 00000 n But crop rotations, overgrazing, lack of regular fire and increased competition from cool-season grasses and legumes have caused these grasses to disappear from much of the state. Switch grass is a hardy, deep-rooted, clump forming, warm season, perennial, rhizomatous bunchgrass that grows about 2.7 m (8 ft. 10 in) high, but is typically shorter than big bluestem grass or Indian grass. 0000435803 00000 n The ascending to widely spreading branches divides into branchlets and pedicellate spikelets. Switchgrass must be grazed before seedheads develop. 0000042587 00000 n 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.

Mohlenbrock. 0000002471 00000 n Switchgrass has so far been bred primarily as a forage crop with a target to enhance its nutritional value [46]. 0000032063 00000 n NUTRITIONAL VALUE : Switchgrass in early growth stages is nutritious. The upright clumps grow 4-5 feet tall and 1½-2 feet wide. The smaller glume is about two-thirds of the length of the spikelet, while the remaining glume and sterile lemma are the same length as the spikelet. 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. An annual plant, it must be reseeded each year for continued production. 0000491596 00000 n The aim of this study was to assess the effect of a three-year application of digestate from an agricultural biogas plant on the physicochemical properties of highly acidic pHKCl 4.4 ± 0.23, silty loam soils with low macronutrient content and on the yield and nutritional value of switchgrass (Panicum virgatum L.) biomass harvested for green fodder. It would have a high amount of biomass per acre and be able to produce a lot of ethanol. 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). 0000027948 00000 n 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). The plant is sometimes used as a windbreak in crop fields. 0000004926 00000 n x�b```f``-a`c`Pef@ a�;�& �M�C�V���@��И�/p��G�Et.4�w��Vј��K�bBRk��@�7'F�V!�Ngv!����N"jՊ3��]=%�qI5�A��Qn E���M���uy�XU\ʙL��)��Y�})�a��\�*� u��KZZFG��(���� a���JBC#:�. 0000025826 00000 n 0000004549 00000 n Switchgrass. 0000001958 00000 n 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. Ligules have bands of white hairs, while the nodes are swollen and often dark-colored. The seed provide food for pheasants, quail, turkeys, doves, and songbirds. The plant prefers moderately deep to deep, somewhat dry to poorly drained, sandy to clay loam soils are best. Switchgrass will benefit from burning of plant residues just prior to initiation of spring growth. Switchgrass can reduce soil erosion and provide warm season pasture for most ruminants. 0000477452 00000 n Switch grass is excellent forage for cattle; however, it has shown toxicity in horses, sheep, and goats. Switchgrass is easily identified … The researchers harvested switchgrass from five CRP fields in southern Wisconsin in August, 1996. Switch grass is excellent forage for cattle; however, it has shown toxicity in horses, sheep, and goats. With proper management, ryegrass yields a high nutrient value, including an average crude protein level of 11.8 percent. grasses when they are at their nutritional best. 1989). Under grazing conditions, switchgrass is sustainable and provides adequate ADG and gain per acre when grazed to a stubble height that is not shorter than 8–12 in. Switchgrass: Tomato: Triticale: Watermelon: Wheat : Discovery of plant amyloids could help create varieties with improved seed quality - This fundamental finding could help improve the nutritional value of plant seeds and even reduce allergenicity of legume seeds in the future. Switchgrass can be successfully established using several seeding practices. 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. Switchgrass is a tall-growing, warm-season, perennial grass that is native to much of the United States including Virginia. 0000466432 00000 n 0000038528 00000 n 0000490378 00000 n Switchgrass is widely adapted and found throughout the United States with the exception of the West Coast. Burning switchgrass together with coal can generate electricity with lower emissions than coal alone. long, ovate, convex along its outer surface, vein less, membranous, and acute at its tip. Rachis, lateral branches, branchlets, and pedicels are light green (rarely light blue and glaucous), glabrous, and slender. Switchgrass offers a wide range of environmental benefits as an alternative energy crop. Seeds are a food source for birds in winter. The stem is round, hollow, and usually, has a reddish tint. It has powdery blue leaves that turn copper in fall and remain well colored through the winter, and pinkish-purple flower plumes. 0000490833 00000 n The compact plants are only about three feet tall, with taller flower spikes with strong pink tones, and dark burgundy seeds. 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. 0000024781 00000 n 0000447350 00000 n Crop Nutrient Tool: Ecological Site Information System: PLANTS Identification Keys ...

Switchgrass becomes stemmy and unpalatable as it matures, but during the target grazing period, it is a favorable forage with a relative feed value (RFV) of 90-104. They are straight, slightly curved, or slightly wiry. m-3. cubense (Griseb.) The urea+plantain combinations resulted in the highest lactate values and lowest pH values (4.2-4.4) for switchgrass. It is a Kurt Bluemel introduction with tightly upright cool blue-green leaves that turn rich amber in fall and fade to light tan by winter. We do not yet know what refineries will pay for switchgrass as cellulosic feedstock. Sudangrass Sudangrass averages 11.6 percent crude protein. Switchgrass was harvested after a killing frost (the first or second week of November each year) to determine yield. Switchgrass can provide habitat and food for many species of wildlife, including cover for large and small mammals, and a nesting place for wild turkey and quail. Each spikelet has 2 glumes, 2 lemmas (one fertile and the other sterile), a palea, and a perfect floret. Switchgrass may also be a more economically advantageous choice for some dairy farmers. Biofuel Source: Switchgrass is a native . Switchgrass will benefit from burning of plant residues just prior to initiation of spring growth. Th ere have been few evaluations of switchgrass (Panicum virgatum L.) cultivars under multiple harvest managements in the northeastern United States. Switchgrass quality is high and its palatability is good when young. year, cut date and fertiliser tr eatment on the variability of switchgrass yield, nutritional value and mineral composition. 53 0 obj <> endobj %PDF-1.4 %���� It is more drought tolerant than many cultivars. Harvesting after frost optimizes nutrient recycling, limits weed problems, and encourages long-term stand persistence. 1991. Data on switchgrass production on marginal sites are limited. Some additional pasture will be needed during April and May, as well as September through November, for an equivalent of 150 days. Erosion Control: Switchgrass is perhaps our most valuable native grass on a wide range of sites. 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. 0000494416 00000 n Forage nutritive value was measured using near-infrared reflectance spectroscopy. 0000034957 00000 n Privacy Policy We do not yet know what refineries will pay for switchgrass as cellulosic feedstock. It is from Amber Wave Gardens, Benton Harbor, Michigan has green foliage that turns shades of deep red in early summer. 0000039164 00000 n 0000478738 00000 n 0000003526 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).
