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. Beginning in April 2008, we will evaluate the utilization and value of switchgrass for stocker cattle. lowest pH values (4.2 – 4.4) for switchgrass. 0000478738 00000 n They are straight, slightly curved, or slightly wiry. startxref Skype: healthbenefit55. The company uses a large tub grinder to reduce the grass stems to a consistent length for feeding into the boiler with maximum efficiency. Switchgrass must be grazed before seedheads develop. 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. 53 51 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. Even as a monoculture, it is better suited than annual grain crops to provide cover, forage, and nesting areas for native species. Erosion Control: Switchgrass is perhaps our most valuable native grass on a wide range of sites. Switchgrass will benefit from burning of plant residues just prior to initiation of spring growth. Switchgrass (Panicum virgatum L.) may have value as forage and a bioenergy feedstock. The warm-season grasses are grazed for 10-14 days when switchgrass and big bluestem are still leafy (10-20” tall). Ani-mals are reluctant to eat mature switchgrass and may refuse it entirely if other feed is available. ... supports investments in research in the areas of human nutrition and health and sustainable dairy production. It is from Amber Wave Gardens, Benton Harbor, Michigan has green foliage that turns shades of deep red in early summer. 0000001316 00000 n long, light green to reddish green (rarely light blue and glaucous), lanceoloid in shape, and glabrous. 0000459832 00000 n 0000447350 00000 n Seeds are a food source for birds in winter. Switchgrass silage benefitted most from addition of alfalfa, urea and plantain. 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). The plant prefers moderately deep to deep, somewhat dry to poorly drained, sandy to clay loam soils are best. 0000494416 00000 n soil erosion and nutrient loss compared to annual crops. Switchgrass pasture needs careful management and must be grazed before seedstalks develop. Switchgrass was harvested after a killing frost (the first or second week of November each year) to determine yield. 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. The upright clumps grow 4-5 feet tall and 1½-2 feet wide. In the East, it performs well on shallow and droughty soils. Ligules have bands of white hairs, while the nodes are swollen and often dark-colored. Crop Nutrient Tool: Ecological Site Information System: PLANTS Identification Keys ... No County Data: Introduced, No County Data: Both, No County Data: Native Status: L48 : AK : HI : PR : VI : NAV : CAN : GL : SPM : NA : Images. Once established, switch grass stand can survive for ten years or longer. In the East, it performs well on shallow and droughty soils. (adsbygoogle = window.adsbygoogle || []).push({}); POLICY The seeds are 3–6 mm long and up to 1.5 mm wide, and are developed from a single-flowered spikelet. 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. Ryegrass tends to die out over time and require seeding, making it costlier to maintain than more persistent species. The leaf blades are up to 15 mm. Yearlings often gain 1.5 to 2 lbs per day during this time. Switchgrass, like a number of other native warm-sea- son grasses (NWSG), can actually produce high-quality forage.

Their livestock were free roaming and would graze the new switchgrass growth in the spring before the new plants were tall enough to withstand defoliation. An annual plant, it must be reseeded each year for continued production. trailer It is a 5 foot tall selection originally found in Dallas and introduced by Change of Scenery Nursery in Columbus, Ohio. Switchgrass May Mean Better Soil Date: July 25, 2008 Source: USDA/Agricultural Research Service Summary: Soils with native grasses such as switchgrass have … glauciphyllum Cassidy, Panicum virgatum var. 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. 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. Switch grass is both a perennial and self-seeding crop, which means farmers do not have to plant and reseed after annual harvesting. 0000032063 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.
