The seeds can be used for food and/or … It is a C4 crop with low input requirements and accumulates high levels of sugars in its stalks. The United States, the world’s largest sorghum producer, is organizing a conference this year on using sorghum as biofuel. Bradley, K., L. Sweets, W. Bailey, and J. Wrather. Charlotte Niemiec is OFI’s editorial assistant The companies intend to work together to support the introduction of sweet sorghum as a source of fermentable sugars at Brazil’s 400 or more ethanol mills. Sweet sorghum is similar to grain sorghum but with sugar-rich stalks and the ability to use water efficiently. Sweet sorghum is a potential biofuel crop because it is capable of producing high yields of ethanol from a combination of easily fermentable sugars and lignocellulosic bagasse. “We need to have plant scientists to understand how the plants grow and mature,” says Slack. 1Freeman et al., 1986. Compared to other biofuel crops unlike sugarcane sweet sorghum … Most of sweet sorghum models for biofuel production use either gasification or fermentation to process plant material into biofuel. It also includes market size and … Stalks of sweet sorghum contain fermentable sugars in the sap equal to 400-600 gallons of ethanol per acre. Several herbicides are labeled for grain and forage sorghum. Fields with irrigation should have higher populations than non-irrigated fields. Photo: Larry Rana, USDA; Wikimedia Commons. The study was concluded prior to the enactment into law of the Biofuels Act (RA 9637) which requires vehicle manufacturers and owners as well as oil companies to use fuels diluted with sugar or starch-derived alcohol to reduce the country's dependence on imported fuel and promote cleaner air. As a result of the efforts of Congressman Raul Grijalva, the United States Department of Energy is also helping to fund the project. Sweet sorghum was first introduced into the United States in 1852. “Sweet sorghum is supposed to be a drought-tolerant crop. Sweet sorghum could be grown on about half of this land. Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture. In favorable environments, sweet sorghum … 2009. The production of sweet sorghum biofuel is quite gentle on the environment. For the biofuels industry, sweet sorghum offers compelling options – if the hybrids work eco - nomically and the adoption is there. Stalks of sweet sorghum contain fermentable sugars in the sap equal to 400-600 gallons of ethanol per acre. To estimate sugar content in juice, use a refractometer to make Brix (%) measurements. Research report: Early deheading of sweet sorghum. Management of biomass and sweet sorghum in the Southwest US. Sweet sorghum may grow up to twenty feet tall and produce significantly higher biomass yields compared to grain sorghum. 611, 55 pp. 2009. Paper presented at the 2008 Joint Annual Meeting, Celebrating the . With an aim to bring sweet sorghum back into mainstream biofuel production, ICRISAT and partners have developed a project, Commercialization of sweet sorghum as a complimentary feedstock for ethanol production in the sugar mills of Maharashtra, Tamil Nadu and Gujarat. Sweet sorghum was compared with corn [Zea mays (L.)] and grain sorghum for potential ethanol yield, energy use efficiency, and greenhouse gas (GHG) emissions at seven dryland site‐years in Nebraska.Seasonal rainfall ranged from approximately 340 to 660 mm. Sweet sorghum is also more water-efficient: sugarcane consumes two and a half units of water to produce one unit of ethanol, whereas sweet sorghum produces one unit of ethanol from one unit of water. Table 1. Sweet sorghum could be grown on about half of this land. “This project is a pilot project,” he says, “which means that we move it beyond the laboratory into the field.” They are looking at how their methods scale to the field to see if they represent viable ways of growing bio-fuel and bio-energy crops in the bright, dry environment of Southern Arizona. Most labs request a forage yield estimate when soil samples are submitted to make crop removal calculations. Sorghum is a multipurpose crop and can be used for food, feed, fuel and fodder. Yield of sweet sorghum varieties at Blairsville, Georgia, and Quicksand, Kentucky.1. When it comes to discussing the potential of sweet sorghum in the biofuels production process, we share in the excitement. Sweet … Most sorghum syrup farmers remove seed heads using cutters mounted on high clearance spray equipment. 2009 International Annual Meetings. Four important varieties from that station are Theis, Keller, Dale, and M81E. To design a sustainable production system, apply enough fertilizer to offset crop removal or spread the bagasse and vinasse back on the field. Bioethanol. It is a multipurpose crop, yielding food in the form of grain and fuel in … The study found that sweet sorghum is comparable if not better than sugarcane for ethanol production. Fortunately, sorghum plants can often compensate for low plant stands by producing several tillers per plant. Sorghum holds promise for … The project is a collaboration between the College of Agriculture and Life Sciences and the College of Engineering. Sweet sorghum is an efficient user of nitrogen fertilizer. Sweet sorghum is also much more water-efficient than most biofuel crops. Biofuel. Sorghum seed head. Soils were deep with medium … As a leading public research university, the University of Arizona is working hard to answer this question through pioneering research in alternative fuels. A study by Memphis Bioworks showed that sweet sorghum processing plants should be located no more than six miles from production fields in the Delta region (Tripp et al., 2009). Nebraska. Before planting, sweet sorghum seed was treated with fluxofenin herbicide seed safener to minimize crop injury. The greatest challenge for large-scale production of sweet sorghum for biofuel is the lack of commercial harvesting equipment.
