Switchgrass offers a wide range of environmental benefits as an alternative energy crop. 0000459832 00000 n thyrsiforme H.P.Linder. The fertile lemma is 2.5–3.5 mm. The upright clumps grow 4-5 feet tall and 1½-2 feet wide. Sudangrass Sudangrass averages 11.6 percent crude protein. King et al. Yearlings often gain 1.5 to 2 lbs per day during this time. 53 51 Expanding on that theme, let's examine switchgrass forage yields and quality over a growing season when the crop is properly managed. 0000038528 00000 n 0000466432 00000 n 0000025285 00000 n (adsbygoogle = window.adsbygoogle || []).push({}); POLICY As forage, Switchgrass provides excellent feed for livestock and other animals. It does poorly on some heavy soils. Vogel, 1995). Beginning in April 2008, we will evaluate the utilization and value of switchgrass for stocker cattle. Rachis, lateral branches, branchlets, and pedicels are light green (rarely light blue and glaucous), glabrous, and slender. Switchgrass hay, on the other hand, averages less than 15% moisture. Harvesting after frost optimizes nutrient recycling, limits weed problems, and encourages long-term stand persistence. The plant has deep rhizomatous and fibrous root system nearly as deep as the plant is tall. After seedheads emerge, nutrient levels become low and switchgrass becomes less acceptable as pasture. Once established, switch grass stand can survive for ten years or longer. 0000025901 00000 n It is discovered growing wild in a Wisconsin meadow, it is one of the bluest selections (but not as sturdy as some so may flop more in wet conditions) that grows 4-5 feet tall, with silvery inflorescences. [21] also found that switchgrass production reduced soil erosion and nutrient loss. Finite nutrients, such as P and K are assumedly remobilized post-senescence in herbaceous feedstocks like switchgrass (Panicum virgatum L.) as a function of environmental signaling and genotype. It would also have low levels of lignin, a material found inside plants that prevents maximum ethanol production. In the East, it performs well on shallow and droughty soils. We do not yet know what refineries will pay for switchgrass as cellulosic feedstock. 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. Burning fields once every 3 to 5 years decreases weed competition, eliminates excessive residue and stimulates switch grass growth. Switchgrass can be successfully established using several seeding practices. Harvesting this crop in August can improve habitat for grassland birds. Many warm-season perennial grasses were once an important part of the plant community throughout Missouri. Switchgrass is often used as hay for cattle as they find it nutritious and palatable. Switchgrass is a perennial, warm-season ornamental grass that is native to North Carolina. The grass's upright growth pattern places its growing point off the soil surface onto its stem, so leaving 25 cm of stubble is important for regrowth. Yields of 2-5 tons per acre can be expect- ed, depending on rainfall and soil type, as well as other environmental conditions. SWITCHGRASS Panicum virgatum L. Plant Symbol = PAVI2 Contributed by: USDA NRCS Plant Materials Program Uses Livestock: Switchgrass is noted for its heavy growth during late spring and early summer. 0000025826 00000 n 0000031767 00000 n It does poorly on some heavy soils. Switchgrass was harvested after a killing frost (the first or second week of November each year) to determine yield. 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). 0000044395 00000 n Real World Switchgrass is offered in a 10 lb. 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. 0000036750 00000 n bag that plants 2-3 Acres and is also available in a … The warm-season grasses are grazed for 10-14 days when switchgrass and big bluestem are still leafy (10-20” tall). 0000465600 00000 n 1991. The glumes and sterile lemma are ovate, convex along their outer surfaces, longitudinally veined, and narrowly acute at their tips. m-3. Both glumes are present and well developed. Switchgrass (Panicum virgatum L.), a native warm‐season perennial grass, is efficient at converting mineral nutrients to harvestable plant tissue with low nutrient removal rates (Vogel et al., 2002); however, scant data exists on optimum P and K applications under multiple forage harvests per annum. In this study, the dry biomass yield vs. N–P–K nutrient uptake relations as well as the N-mineralization and the N-fertilization recovery fraction for switchgrass (cv. 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. An annual cutting in fall or winter suffices for biomass production since its value is based on total tonnage, not nutritional quality. Each fertile culm terminates in an inflorescence that is 7-20 inches long and about one-half as much across when it is fully open. Burning switchgrass together with coal can generate electricity with lower emissions than coal alone. It has powdery blue leaves that turn copper in fall and remain well colored through the winter, and pinkish-purple flower plumes. startxref NUTRITIONAL VALUE : Switchgrass in early growth stages is nutritious. 0000477452 00000 n 0000025974 00000 n Privacy Policy 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. Erosion Control: Switchgrass is perhaps our most valuable native grass on a wide range of sites. 103 0 obj<>stream 0000042126 00000 n It is a warm season grass that is capable of thriving in wide range of environments. 0000024781 00000 n The compact plants are only about three feet tall, with taller flower spikes with strong pink tones, and dark burgundy seeds. Switchgrass can reduce soil erosion and provide warm season pasture for most ruminants. 0000000016 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. 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. © 2020 Healthbenefitstimes. They are straight, slightly curved, or slightly wiry. The ideal switchgrass wouldn’t possess one trait, but many. 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). 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. Forage nutritive value was measured using near-infrared reflectance spectroscopy. trailer The leaves are wider than many other cultivars, and plants have a fuller shape and denser flower spikes that appear in distinct layers. 0000003526 00000 n What Switchgrass To Buy It is more drought tolerant than many cultivars. Along the rachis (central stalk) of the inflorescence, there are either solitary lateral branches or pseudo-whorls of 2-3 lateral branches. The plant prefers moderately deep to deep, somewhat dry to poorly drained, sandy to clay loam soils are best. 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. year, cut date and fertiliser tr eatment on the variability of switchgrass yield, nutritional value and mineral composition. 0000031364 00000 n After seedheads emerge, though, nutrient levels decline rapidly and animals refuse to eat much of it. With proper management, ryegrass yields a high nutrient value, including an average crude protein level of 11.8 percent.

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. 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. Switchgrass May Mean Better Soil Date: July 25, 2008 Source: USDA/Agricultural Research Service Summary: Soils with native grasses such as switchgrass have … Before seedheads develop, forage quality is high and palat-ability good. virgatum (switchgrass). Stem is round and can have a red to straw colored tint. Market Value of Switchgrass. warm season grass with the ability to produce moderate to high During the period of bloom, the spikelets are 3-5 mm. 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. 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. 0000478738 00000 n 53 0 obj <> endobj Skype: healthbenefit55. %%EOF yield and its nutritional value by intercropping with alfalfa (Medicago sativaL). However, it is in its infancy as a bioenergy production crop since some of the feedstock target traits are different from forage traits. They are open at their apices, forming a V-shape. The nutrient content of this forage can be as high as 16-17 percent crude protein, if harvested correctly. The silage quality of switchgrass could be improved with addition of 25 – 50 per cent alfalfa or addition of urea (6 or 12 g/6 kg grass) in combination with plantain (200 or 400 g /6 kg grass). 0 0000002471 00000 n 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. It makes a good substitute for some of the larger Miscanthus cultivars.

Switchgrass must be grazed before seedheads develop. It provides good warm-season pasture and high quality hay for livestock. 0000494416 00000 n Switchgrass, as noted above, can provide forage for one AU for 90 days from 0.45 acre (2.2 AU per acre). Market Value of Switchgrass. Before seedheads develop, forage quality is high and palat-ability good. 1989). soil erosion and nutrient loss compared to annual crops. To date switchgrass has been bred primarily to enhance its nutritional value as a forage crop for livestock (Vogel et al. Leaf sheaths are about the same color as the blades and hairless. It is a German selection that grows 3½-4 feet tall and has red leaf tips early in the growing season and burgundy fall foliage color with burgundy seed heads. 0000447350 00000 n This mismanagement weakened the stands and eventually led to their demise. It is from Amber Wave Gardens, Benton Harbor, Michigan has green foliage that turns shades of deep red in early summer. Potassium, a critical element involved in enzyme activation, protein synthesis, stomatal regulation, plant–water relations, and cation–anion balance in the plant [ 14 ] can affect crop growth when it is deficient. The researchers harvested switchgrass from five CRP fields in southern Wisconsin in August, 1996. Switchgrass is easily identified … The company uses a large tub grinder to reduce the grass stems to a consistent length for feeding into the boiler with maximum efficiency. Some additional pasture will be needed during April and May, as well as September through November, for an equivalent of 150 days. St. Petersburg, Russian Federation December 2, 2020. Burning fields once every 3 to 5 years decreases weed competition, eliminates excessive residue and stimulates switch grass growth. Significant differences were also found among 40 switchgrass rust isolates for their germination percentage (p < 0.0001) (data not shown). 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. 0000033850 00000 n 0000005180 00000 n Switchgrass, like a number of other native warm-sea- son grasses (NWSG), can actually produce high-quality forage.

Data from: Switchgrass cultivar, yield, and nutrient removal responses to harvest timing . This inflorescence is an airy panicle of spikelets. The urea+plantain combinations resulted in the highest lactate values and lowest pH values (4.2-4.4) for switchgrass. 133. Several alternate leaves occur along the entire length of each culm. Switchgrass pasture needs careful management and must be grazed before seedstalks develop. Switch grass is excellent forage for cattle; however, it has shown toxicity in horses, sheep, and goats. %PDF-1.4 %���� Ryegrass tends to die out over time and require seeding, making it costlier to maintain than more persistent species. The monoculture stands of grass that FDC manages are baled and then stored under cover. It can be used as an energy substitute and is often considered a good candidate for bio-fuel, especially ethanol fuel production, due to its hardiness against poor soil and climate conditions, rapid growth and low fertilization and herbicide requirements. Culms are light to medium green (less often light blue and glaucous), terete, glabrous, and fairly stout. 0000001316 00000 n Switchgrass is widely adapted and found throughout the United States with the exception of the West Coast. 0000032063 00000 n Switchgrass is an excellent crop for bioenergy fuel, and although it is toxic to horses, sheep, and goats, cattle have no difficulty in processing this abundant plant. 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 used for wildlife food and cover should be burned once every 3 to 4 years to reduce mulch accumulations that Switchgrass will benefit from burning of plant residues just prior to initiation of spring growth. Switch grass is excellent forage for cattle; however, it has shown toxicity in horses, sheep, and goats. Switchgrass produces large seeds on a spangled-type seed head. Switch grass is both a perennial and self-seeding crop, which means farmers do not have to plant and reseed after annual harvesting. Switchgrass does well on a wide variety of soil types. It is also tolerant to wet areas. scorteum H.P.Linder, Panicum virgatum var. 0000436383 00000 n Th ere have been few evaluations of switchgrass (Panicum virgatum L.) cultivars under multiple harvest managements in the northeastern United States. Switchgrass may have value for stockers because of its early spring availability, high yields, perennial life form, wide adaptability and low fertilization requirements. on shooting preserves. 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).
