This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Petroleum prices have made alternative fuel crops a viable option for ethanol production. Sweet sorghum [Sorghum bicolor] is a non-food crop that may produce large quantities of ethanol with minimal inputs. Eleven cultivars were planted in 2008 and 2009 as a half-season crop. Four-row plots 6.9 m by 0.5 m, were monitored bimonthly for °Brix, height, and sugar accumulation. Yield and extractable sap were taken at the end of season. Stalk yield was greatest for the cultivar Sugar Top (4945 kg ha -1) and lowest for Simon (1054 kg ha−1). Dale ranked highest ethanol output (807 L ha−1) while Simon (123 L ha−1) is the lowest. All cultivars peak Brix accumulation occurs in early October. Individual sugar concentrations indicated sucrose is the predominant sugar with glucose and fructose levels dependent on cultivar. Supplemental ethanol in fermented wort was the best preservative tested to halt degradation of sorghum wort.

This book was released on 2012-10-05 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of driving forces, including the soaring global crude oil prices and environmental concerns in both developed and developing nations has triggered a renewed interest in the recent years on the R&D of biofuel crops. In this regard, many countries across the globe are investing heavily in the bioenergy sector for R&D to increase their energy security and reduce their dependence on imported fossil fuels. Currently, most of the biofuel requirement is met by sugarcane in Brazil and corn in the United States, while biodiesel from rapeseed oil in Europe. Sweet sorghum has been identified as a unique biofuel feedstock in India since it is well adapted to Indian agro-climatic conditions and more importantly it does not jeopardize food security at the cost of fuel. Sweet sorghum [Sorghum bicolor (L.) Moench] is considered as a SMART new generation energy crop as it can accumulate sugars in its stalks similar to sugarcane, but without food¬¬-fuel trade-offs and can be cultivated in almost all temperate and tropical climatic conditions and has many other advantages. The grain can be harvested from the panicles at maturity. There is no single publication detailing the agronomic and biochemical traits of tropical sweet sorghum cultivars and hybrid parents. Hence, an attempt is made in this publication- “Characterization of improved sweet sorghum cultivars” to detail the complete description of cultivars. This book serves as a ready reference on the detailed characterization of different improved sweet sorghum genotypes following the PPVFRA guidelines for the researchers, entrepreneurs, farmers and other stakeholders to identify the available sweet sorghum cultivars and understand their yield potential in tropics.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the feasibility of producing sweet sorghum as an ethanol feedstock in Mississippi. An enterprise budgeting system is used along with estimates of transportation costs to estimate farmers' breakeven costs for producing and delivering sweet sorghum biomass. This breakeven cost for the farmer, along with breakeven costs for the producer based on wholesale ethanol price, production costs, and transportation and marketing costs for the refined ethanol, is used to estimate the amounts that farmers and ethanol producers would be willing to accept (WTA) and willing to pay (WTP), respectively, for sweet sorghum biomass. These WTA and WTP estimates are analyzed by varying key factors in the biomass and ethanol production processes. Deterministic and stochastic models are used to estimate profits for sweet sorghum and competing crops in two representative counties in Mississippi, with sweet sorghum consistently yielding negative per-acre profits in both counties.

Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted to evaluate the potential of sweet sorghum as a fuel ethanol feedstock for the southern coastal plain. Several cultural aspects were studied and a methol for rapid evaluation of the fermentable sugar concentrtions in the stalks was developed. The major findings of the studies were. 1. Wray, M81E, and MN1500 were the highest yielding early, medium, and late-maturing cultivars tested. Because of its high sugar concentration and resistance to lodging, Wray was the best single cultivar. 2. On the better agricultural soils of the area, the yield potential is five to six metric tons of total sugars per hectare. 3. The best planting time is in early May. Yields are reduced in plantings after mid-May because of early maturity and damage from the fall armyworm (Spodoptera frugiperda (J.E. Smith). The best harvest time is at the soft, to hard-dough stages of the seed. To maintain a constant supply of high-yielding sweet sorghum for a fuel ethanol plant, it was demonstrated the combinations of cultivars, planting dates, and harvest stages resulted in 95% of maximum sugar yield over a four-month period. 5. Nutrient requirements for sweet sorghum were low in comparisons to corn. No response to P or K was found when the soil test was high or medium for the elements, respectively. For a medium P soil test, yield responses were obtained to at least 25 kg P/ha. For a low K test, response was obtained to 186 kg K/ha. Response was obtained to about 100 kg N/ha. The N application should be split, with about one-half to two-thirds applied as a sidedressing when the sorghum is 30 to 60 cm high. No response was found to a 10-34-0 starter fertilizer, but the P soil test was high in this study. 6. The actual removal of nutrients by a sweet sorghum crop was determined to be 1,5 kg/MT fresh stalks for N, 0.3 for P, 1.8 for K, 0,6 for Ca and 0,3 for Mg. 7. No yield advantage was found in decreasing the row sapcing from 90 cm nor was there as advantage to increasing the population above 75 thousand plants per hectare. 8. The best control of annual grasses was obtained with a propazine plus metolachlor treatment. 9. No positive responses were found to the application of several growth regulators. 10. As automated analysis for determining the concentrations of total sugars in fresh or frozen sweet sorghum stalks was developed using an AutoAnalyzer II.

Download or read book Heterosis and Composition of Sweet Sorghum written by Rebecca J. Corn and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sweet sorghum (Sorghum bicolor) has potential as a bioenergy feedstock due to its high yield potential and the production of simple sugars for fermentation. Sweet sorghum cultivars are typically tall, high biomass types with juicy stalks and high sugar concentration. These sorghums can be harvested, milled, and fermented to ethanol using technology similar to that used to process sugarcane. Sweet sorghum has advantages in that it can be planted by seed with traditional planters, is an annual plant that quickly produces a crop and fits well in crop rotations, and it is a very water-use efficient crop. Processing sweet sorghum is capital intensive, but it could fit into areas where sugarcane is already produced. Sweet sorghum could be timed to harvest and supply the sugar mill during the off season when sugarcane is not being processed, be fit into crop rotations, or used in water limiting environments. In these ways, sweet sorghum could be used to produce ethanol in the Southern U.S and other tropical and subtropical environments. Traditionally, sweet sorghum has been grown as a pureline cultivar. However, these cultivars produce low quantities of seed and are often too tall for efficient mechanical harvest. Sweet sorghum hybrids that use grain-type seed parents with high sugar concentrations are one way to overcome limitation to seed supply and to capture the benefits of heterosis. There are four objectives of this research. First to evaluate the importance of genotype, environment, and genotype-by-environment interaction effects on the sweet sorghum yield and composition. The second objective is to determine the presence and magnitude of heterosis effects for traits related to sugar production in sweet sorghum. Next: to study the ability of sweet sorghum hybrids and cultivars to produce a ratoon crop and determine the contribution of ratoon crops to total sugar yield. The final objective is to evaluate variation in composition of sweet sorghum juice and biomass. Sweet sorghum hybrids, grain-type sweet seed parents, and traditional cultivars that served as male parents were evaluated in multi-environment trials in Weslaco, College Station, and Halfway, Texas in 2007 and 2008. Both genotype and environment influenced performance, but environment had a greater effect than genotype on the composition of sweet sorghum juice and biomass yield. In comparing performance, elite hybrids produced fresh biomass and sugar yields similar to the traditional cultivars while overcoming the seed production limitations. High parent heterosis was expressed among the experimental hybrids for biomass yield, sugar yield and sugar concentration. Additional selection for combining ability would further enhance yields and heterosis in the same hybrid. Little variation was observed among hybrids for juice and biomass composition suggesting that breeding efforts should focus on yield before altering plant composition.

Download or read book Introduction to Biomass Energy Conversions written by Sergio Capareda and published by CRC Press. This book was released on 2013-07-09 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential that biomass energy has to supplement traditional fuels and reduce greenhouse gas emissions has put it front and center in the plan to replace fossil-based fuels with renewable fuels. While much has been written about biomass conversions, no single textbook contains all the information needed to teach a biomass conversion course—until now. Introduction to Biomass Energy Conversions presents a comprehensive review of biomass resources available for conversion into heat, power, and biofuels. The textbook covers biomass characterization and discusses facilities, equipment, and standards (e.g. ASTM or NREL) used for analysis. It examines the range of biomass resources available for conversion and presents traditional biomass conversion processes along with extensive biomass characterization data tables, illustrations, and graphical presentations of the various biomass energy conversion processes. The author also describes how to set up a laboratory for biomass energy conversion, and presents economics and sustainability issues. Loaded with real-world examples, the text includes numerous worked examples and problems in each chapter. No one knows what the price of oil will be next year or in future decades. It is governed by many factors other than supply and demand (politics, wars, etc.), however, whatever the future of energy is, bio-fuels will play an important role. This technical guide prepares students for managing bio-refineries, no matter what type of bio-fuel is produced. It also provides practicing engineers with a resource for starting a small bio-fuel business.

Available in PDF, EPUB and Kindle. Book excerpt: Sweet sorghum has the potential in Missouri for production as a biofuel feedstock, but little is known of the crop's yields and appropriate nitrogen management for optimizing ethanol yields. This thesis is a collection of three field studies examining the potential for sweet sorghum (Sorghum bicolor (L.) Moench) to be adopted as a biofuel feedstock for ethanol production in the Midwestern U.S. Limited research exists examining the optimum nitrogen fertilizer rate for maximum ethanol yields as well as sweet sorghum's adaptability to the lower Midwestern states. The first study included testing the effects of five N fertilizer rates (0, 56, 112, 168, 224 kg-N ha-1) on the production of two sweet sorghum cultivars (Dale and Top 76-6) over three years in central Missouri. Yields measured included dry matter, stem juice, Brix, fermentable sugar, theoretical juice ethanol, theoretical lignocellulosic ethanol, and total theoretical ethanol. N fertilizer treatment mostly increased yields, as total dry matter yield averaged 16.8 Mg ha-1, fermentable sugar yield averaged 1055 kg ha-1, and total ethanol yield averaged 5828 L ha-1 . The optimal range for N fertilizer rates was between 112 and 168 kg N ha-1. The second study included determining the above-ground plant N concentration, plant N content, N recovery efficiency, and physiological N-use efficiency of sorghum from the first study. Nitrogen treatment significantly affected plant N concentration and N content. Greater yields resulted in greater N recovery efficiency but did not always result in greater N-use efficiency. The optimum range for highest nitrogen recovery and use efficiencies was identified as 0-112 kg N ha-1 . The purpose of the third study was to better understand sweet sorghum's affect on soil organic carbon. This involved comparing the effects of an alternative sweet sorghum--soybean (Glycine max L.) rotation to a maize (Zea mays L.)--soybean rotation at three study sites in Missouri and Arkansas on yields, soil organic carbon, the labile soil carbon fraction and the physically-stabilized fraction. Sweet sorghum ethanol yields were greater than maize yields across sites, but the soil carbon similarly decreased regardless of crop and location. Sweet sorghum is a high-yielding biomass feedstock that shows promise for production in Missouri, especially in marginal lands. With proper nitrogen fertilizer management sweet sorghum is shown to be an efficient plant for ethanol yield, but it may negatively affect soil organic carbon following land-use changes for biofuel production.

This book was released on 2021-01-04 with total page 932 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sorghum is the most important cereal crop grown in the semi-arid tropics (SAT) of Africa, Asia, Australia and Americas for food, feed, fodder and fuel. It is the fifth most important cereal crop globally after rice, wheat, maize and barley, and plays a major role in global food security. Sorghum is consumed in different forms for various end-uses. Its grain is mostly used directly for food purposes. After the release of the proceedings of two international symposia in the form of books “Sorghum in Seventies” and “Sorghum in Eighties”, global sorghum research and development have not been documented at one place. Of course, few books on sorghum have been released that focus on specific issues/research areas, but comprehensive review of all aspects of recent development in different areas of sorghum science has not been compiled in the form a single book. This book is intended to fill in a void to bridge the gap by documenting all aspects of recent research and development in sorghum encompassing all the progress made, milestones achieved across globe in genetic diversity assessment, crop improvement and production, strategies for high yield, biotic and abiotic stress resistance, grain and stover quality aspects, storage, nutrition, health and industrial applications, biotechnological applications to increase production, including regional and global policy perspectives and developmental needs. This book will be an institutional effort to compile all the latest information generated in research and development in sorghum across the globe at one place.
