In fact Kanlow, along with ‘Alamo ’ switchgrass (another Plant Materials Program release from Texas) have been the two main lines of germplasm that have been the focus of intense research by the scientific community since the DOE indicated that switchgrass would be designated as a model plant for An upland type switchgrass, leafy and medium in height. Lowland types tend to grow taller and more rapidly than upland types. I already have a mixture of Cave-In-Rock and Blackwell planted 4 years ago, but looking for something a bit taller. Some of these The ability to produce high yields of biomass and the adaptability of Alamo are two of the main advantages for its use as a Biofuel. Alamo is a vigorous, perennial bunch grass that grows throughout most of the United States. Alamo has the potential to be used as a renewable Biofuel resource in the Southern United States. Blackwell. I'm looking to try out an acre or so and just looking for some in-sight. Varieties: Alamo. Blackwell Cultivar plant material is from a single plant collected near Blackwell, Oklahoma and was developed for forage and resistance to disease. Alamo produces more forage. Two types of switchgrass, lowland and upland, are available for planting. Other switchgrass varieties include Alamo, Blackwell, Carthage, Cave-in-Rock, Dacotah, Forestburg, Kanlow, Nebraska 28, Pathfinder, Shawnee, Shelter and Summer. Conservation Uses . Unlike previously existing varieties, Alamo is adapted to and performs well in the southern half of Texas. Adapted upland cultivars include Blackwell and Cave-In-Rock. The objective of the study was to examine lowland (Alamo and Kanlow) and upland (Blackwell and Caddo) cultivars of switchgrass (Panicum virgatum L.) for differences in response to water deficit and nitrogen fertilizer.Cultivars were grown in pots with fritted clay at two water levels: well watered and deficit conditions (−0.1 and −1.0 MPa) and two nitrogen levels (10 and 100 kg ha −1). In the East, it performs well on shallow and droughty soil. It does poorly on heavy soils. With supplemental irrigation in areas with less … Good resistance to disease, widely adapted in north TX, OK, NE, and KS. Does anyone have any experience with Southern Variety Alamo Switchgrass plantings in Michigan? Because of its deep penetrating root system, it can handle drought periods better than most grasses and provides outstanding erosion control. You are only paying for viable seed. Alternate Names. Alamo Switchgrass Seed - Switchgrass, a warm season, vigorous perennial can be found growing throughout the United States. Sunburst, Trailblazer and Blackwell are well-known upland varieties identified for bioenergy use, based on their region of adaptation and performance. Prices listed are based on pure live seed weight, not bulk weight. Let me know. Lowland cultivars adapted to the southern plains include Alamo and Kanlow. It grows to a height of 3 to 8 feet tall, depending on the variety. Switchgrass grows naturally on prairies, open oak and pine woodlands, shores, riverbanks, and high brackish marshes along maritime forest ecotones. Most common varieties are Alamo and Blackwell. On suitable soils, switchgrass is climatically adapted throughout the most of the United States. Biomass data were produced in an experiment with four commercial switchgrass cultivars (Alamo, Blackwell, Kanlow, and Cave‐in‐Rock) and five experimental lines over 4 yr at Stillwater, OK. One of the experimental lines, Cimarron, was released as a cultivar in 2008 during the experiment. One of the Big 4 Prairie grasses. Switchgrass has numerous roots reaching to ten feet deep, as well as underground rhizomes making it an important grass for use in conservation programs. (Released 1944, source of ecotype: Blackwell, OK) Kanlow. Alamo switchgrass was originally collected along the Frio River in Live Oak County, Texas. This grass grows 3 to 8 feet high, with large, vigorous rhizomes. Switchgrass is an important forage plant and potential source of biomass for biofuel production. Moderately deep to deep, somewhat dry to poorly drained, sandy to clay loam soils are best. Switchgrass is distributed throughout the majority of Panic raide.
