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. Switchgrass May Mean Better Soil Date: July 25, 2008 Source: USDA/Agricultural Research Service Summary: Soils with native grasses such as switchgrass have … It provides good warm-season pasture and high quality hay for livestock. Vogel, 1995). trailer Market Value of Switchgrass. 0000031364 00000 n Ryegrass tends to die out over time and require seeding, making it costlier to maintain than more persistent species. 0000491272 00000 n on shooting preserves. It would also have low levels of lignin, a material found inside plants that prevents maximum ethanol production. 133. 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. Switchgrass may have value for stockers because of its early spring availability, high yields, perennial life form, wide adaptability and low fertilization requirements. 0000494169 00000 n Expanding on that theme, let's examine switchgrass forage yields and quality over a growing season when the crop is properly managed. There is a need to genetically improve switchgrass Burning switchgrass together with coal can generate electricity with lower emissions than coal alone. Terms & conditions The seed provide food for pheasants, quail, turkeys, doves, and songbirds. 0000025285 00000 n m-3. 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. Their blades are ascending to widely spreading. Th ere have been few evaluations of switchgrass (Panicum virgatum L.) cultivars under multiple harvest managements in the northeastern United States. Switchgrass will benefit from burning of plant residues just prior to initiation of spring growth. It would have a high amount of biomass per acre and be able to produce a lot of ethanol. Several alternate leaves occur along the entire length of each culm. defoliation on switchgrass responses. Switchgrass is often used as hay for cattle as they find it nutritious and palatable. In these studies, the first grazing of warm-season grasses occurs in early June, two to three weeks earlier than the normal late June/early July start date. 0000025974 00000 n 0000459832 00000 n 0000034957 00000 n In the East, it performs well on shallow and droughty soils. With proper management, ryegrass yields a high nutrient value, including an average crude protein level of 11.8 percent. The plant is sometimes used as a windbreak in crop fields. 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). The ideal switchgrass wouldn’t possess one trait, but many. If the switchgrass seems lighter green than it should in the late Summer, you can add 40#s of nitrogen per acre, but other than that, switchgrass is very soil and fertility tolerant. 0000042475 00000 n All rights reserved. <]>> The monoculture stands of grass that FDC manages are baled and then stored under cover. However, in the past decade, switchgrass has been a focus for input in biofuel production. Switchgrass produces high amounts of biomass that can be used for solid biofuel production. across and 2 inches long. 0000435803 00000 n 0000042126 00000 n Flowers have a well-developed panicle, often up to 60 cm long, and it bears a good crop of seeds. The nutrient content of this forage can be as high as 16-17 percent crude protein, if harvested correctly. The leaves curl slightly when the rosy panicles appear. Harvesting this crop in August can improve habitat for grassland birds. 0000025826 00000 n The plant prefers moderately deep to deep, somewhat dry to poorly drained, sandy to clay loam soils are best. The warm-season grasses are grazed for 10-14 days when switchgrass and big bluestem are still leafy (10-20” tall). Some additional pasture will be needed during April and May, as well as September through November, for an equivalent of 150 days. 0000041883 00000 n Harvesting after frost optimizes nutrient recycling, limits weed problems, and encourages long-term stand persistence. This inflorescence is an airy panicle of spikelets. Although regular grass provides nutrition and fiber to livestock and other animals, the high cellulose content is difficult for digestion by humans and, as a result, provides very few nutrients. An annual cutting in fall or winter suffices for biomass production since its value is based on total tonnage, not nutritional quality. Erosion Control: Switchgrass is perhaps our most valuable native grass on a wide range of sites. Switch-grass has been bred primarily to enhance its nutritional value as a forage crop (Vogel et al., 1989). Significant differences were also found among 40 switchgrass rust isolates for their germination percentage (p < 0.0001) (data not shown). The seeds are 3–6 mm long and up to 1.5 mm wide, and are developed from a single-flowered spikelet. Burning fields once every 3 to 5 years decreases weed competition, eliminates excessive residue and stimulates switch grass growth. long, ovate, convex along its outer surface, vein less, membranous, and acute at its tip. Year , fertiliser treatment and cut date were considered fixed e ff ects. 0000044395 00000 n scorteum H.P.Linder, Panicum virgatum var. Switchgrass hay, on the other hand, averages less than 15% moisture. 0000465600 00000 n Before seedheads develop, forage quality is high and palat-ability good. NUTRITIONAL VALUE : Switchgrass in early growth stages is nutritious. 1989). St. Petersburg, Russian Federation December 2, 2020. They were replaced by cool-s… The leaf blades are up to 15 mm. Due to its potential to spread some wildlife biologists have reduced or eliminated the use of switchgrass in some plantings. thyrsiforme H.P.Linder. Switchgrass may also be a more economically advantageous choice for some dairy farmers. 0000005180 00000 n Disclaimer, e-mail: [email protected] Market Value of Switchgrass. 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).
