Ligules have bands of white hairs, while the nodes are swollen and often dark-colored. It is a tall selection introduced by former Bluemount Nursery of Maryland that can reach 7-8 feet, with light metallic blue leaves and gold fall color. 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. virgatum (switchgrass). It is much earlier than other red cultivars and butter yellow in fall. 0000005180 00000 n However, in the past decade, switchgrass has been a focus for input in biofuel production. 0000001316 00000 n Switchgrass is harvested using conventional haying equipment. Beginning in April 2008, we will evaluate the utilization and value of switchgrass for stocker cattle. Switchgrass. Switchgrass has so far been bred primarily as a forage crop with a target to enhance its nutritional value [46]. 0000491596 00000 n However, it is in its infancy as a bioenergy production crop since some of the feedstock target traits are different from forage traits. 0000039164 00000 n The nutrient content of this forage can be as high as 16-17 percent crude protein, if harvested correctly. glauciphyllum Cassidy, Panicum virgatum var. During spring 2013, in two switchgrass pure stands (varieties Alamo and Blackwell, respectively), alfalfa was established through direct seeding implementing a split-plot experimental design. It provides good warm-season pasture and high quality hay for livestock. 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. To date switchgrass has been bred primarily to enhance its nutritional value as a forage crop for livestock (Vogel et al. 0 0000003526 00000 n 0000436383 00000 n Poplar chips (4' × 5') round bale (dry weight) 105 : Chopped : 108 : Holocellulose % All rights reserved. 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. 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. King et al. Burning switchgrass together with coal can generate electricity with lower emissions than coal alone. Both glumes are present and well developed. After seedheads emerge, though, nutrient levels decline rapidly and animals refuse to eat much of it. 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. Even as a monoculture, it is better suited than annual grain crops to provide cover, forage, and nesting areas for native species. 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. 0000465600 00000 n Data on switchgrass production on marginal sites are limited. Switchgrass (SG) was widespread in open areas before settlers populated an area and remained in one place year after year. 53 0 obj <> endobj trailer Ryegrass tends to die out over time and require seeding, making it costlier to maintain than more persistent species. lowest pH values (4.2 – 4.4) for switchgrass. click on a thumbnail to view an image, or see all the Panicum thumbnails at the Plants Gallery Robert H. Mohlenbrock. 0000031364 00000 n startxref The leaves curl slightly when the rosy panicles appear. Burning fields once every 3 to 5 years decreases weed competition, eliminates excessive residue and stimulates switch grass growth. Switchgrass will benefit from burning of plant residues just prior to initiation of spring growth. Switchgrass can be successfully established using several seeding practices. Forage nutritive value was measured using near-infrared reflectance spectroscopy. Switchgrass silage benefitted most from addition of alfalfa, urea and plantain. Ani-mals are reluctant to eat mature switchgrass and may refuse it entirely if other feed is available. However, these grasses can complement cool-season pastures if managed properly. Harvesting this crop in August can improve habitat for grassland birds. 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. 0000025974 00000 n 0000001878 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#:�. Switchgrass is a tall-growing, warm-season, perennial grass that is native to much of the United States including Virginia. 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. They are straight, slightly curved, or slightly wiry. It is drought tolerant and grows well on shallow rocky soils. Burning fields once every 3 to 5 years decreases weed competition, eliminates excessive residue and stimulates switch grass growth. Switch grass is both a perennial and self-seeding crop, which means farmers do not have to plant and reseed after annual harvesting. The seeds are 3–6 mm long and up to 1.5 mm wide, and are developed from a single-flowered spikelet. Switchgrass (Panicum virgatum L.) may have value as forage and a bioenergy feedstock. Milium virgatum var. 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.
