Book Description
The purpose of this research is to evaluate and gain a better understanding of the economic feasibility of Kansas farmers growing energy sorghum for biofuel production. The net returns for 11 crop systems that included a no-till or reduced-till option and the rotations involved wheat, grain sorghum, dual-purpose sorghum, and photoperiod sensitive sorghum were simulated in SIMETAR© developed by Richardson, Shumann, and Feldman (2004) using historical data on yields and prices. The price and yield data originates from an agronomic study conducted in Hesston, KS. The biomass yields for the 3 varieties of sorghum are based on experimental work performed in Manhattan, KS. The sorghum biomass prices were obtained from the United States Department of Agriculture Agricultural Marketing Service. Costs for the crop systems are based on the 2014 Kansas State University Herbicide handbook (Thompson et al. 2014), Dhuyvetter, O'Brien, and Tonsor (2014), and Dhuyvetter (2014). The net returns were simulated under five contract scenarios including: a Spot Market contract, a Minimum Price contract, a BCAP Price contract, and 2 levels of the Gross Revenue Guarantee contracts - 60% and 100%. Risk analysis was performed on the simulated net returns through use of the Excel add-in SIMETAR©. Stochastic efficiency analysis was used to evaluate the systems based on the distribution of net returns and risk preferences. The findings are summarized around three important factors influencing farmers' economic feasibility of growing sorghum for biofuel use: crop systems, risk preferences, and contract specification. Results indicate that the no-till wheat and dual-purpose sorghum crop system without biomass production has the lowest costs and the no-till wheat and photoperiod sensitive sorghum system has the highest production cost. The crop systems that have a no-till option allow for the highest grain and biomass yields. Also, crop systems rotated with wheat are more preferred among producers due to higher net returns. The NTWDPS With system under the BCAP Price contract has the highest net returns and is highest in preference. The findings indicate that the risk aversion does affect the decision to produce sorghum for biofuel, but the effect is not very significant. In terms of contract specification, the results indicate that for Kansas producers, the BCAP Price contract will offer the highest net returns. These findings contribute additional insight on factors affecting Kansas farmers' economic feasibility of producing sorghum for biofuel and can have important implications for biofuel industry actors and policy makers.

Book Description
Environmental and political concerns centered on energy use from gasoline have led to a great deal of research on ethanol production. The goal of this thesis is to determine if it is profitable to produce ethanol in Texas using sweet sorghum juice. Four different areas, Moore, Hill, Willacy, and Wharton Counties, using two feedstock alternatives, sweet sorghum only and sweet sorghum and corn, will be analyzed using Monte Carlo simulation to determine the probability of economic success. Economic returns to the farmers in the form of a contract price for the average sweet sorghum yield per acre in each study area and to the ethanol plant buying sweet sorghum at the contract price will be simulated and ranked. The calculated sweet sorghum contract prices offered to farmers are $9.94, $11.44, $29.98, and $36.21 per ton in Wharton, Willacy, Moore, and Hill Counties, respectively. The contract prices are equal to the next most profitable crop returns or ten percent more than the total cost to produce sweet sorghum in the study area. The wide variation in the price is due to competing crop returns and the sweet sorghum growing season. Ethanol production using sweet sorghum and corn is the most profitable alternative analyzed for an ethanol plant. A Moore County ethanol plant has the highest average net present value of $492.39 million and is most preferred overall when using sweet sorghum and corn to produce ethanol. Sweet sorghum ethanol production is most profitable in Willacy County but is not economically successful with an average net present value of $-11.06 million. Ethanol production in Hill County is least preferred with an average net present value of $-712.00 and $48.40 million when using sweet sorghum only and sweet sorghum and corn, respectively. Producing unsubsidized ethanol from sweet sorghum juice alone is not profitable in Texas. Sweet sorghum ethanol supplemented by grain is more economical but would not be as profitable as producing ethanol from only grain in the Texas Panhandle. Farmers profit on average from contract prices for sweet sorghum when prices cover total production costs for the crop.

Book Description
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.

Book Description
This new volume, Advances in Sorghum Science: Botany, Production, and Crop Improvement, provides an easy-to-read and comprehensive treatment of the sorghum crop. With the world’s production of sorghum topping over 55 million tons annually, sorghum is very important for as a staple dietary food for much of the world as a rich source of micronutrients and macronutrients, as an ingredient in the processing of many foods, and as a source of fodder. The authors of the volume provide detailed information on sorghum from several disciplines and bring together recent literature under one umbrella. The book covers the various aspects of the sorghum crop, starting from its origin, to its domestication, and going on to biotechnology of the crop. It describes sorghum production, ideotypes, botany, physiology, abiotic and biotic factors affecting crop productivity, methods of cultivation, postharvest management, grain quality analysis for food processing, improvement of sorghum crop, and research advancements in breeding and biotechnology. This valuable resource will be helpful to researchers and scientists working to understand the relation between various disciplines and the implementation of new methods and technology for crop improvement and higher productivity. The multi-pronged approach will help to enable the increase sorghum productivity to meet the world’s growing demands.

Book Description
The development of a robust source of renewable transportation fuel will require a large amount of biomass feedstocks. It is generally accepted that in addition to agricultural and forestry residues, we will need crops grown specifically for subsequent conversion into fuels. There has been a lot of research on several of these so-called "dedicated bioenergy crops" including switchgrass, miscanthus, sugarcane, and poplar. It is likely that all of these crops will end up playing a role as feedstocks, depending on local environmental and market conditions. Many different types of sorghum have been grown to produce syrup, grain, and animal feed for many years. It has several features that may make it as compelling as other crops mentioned above as a renewable, sustainable biomass feedstock; however, very little work has been done to investigate sorghum as a dedicated bioenergy crop. The goal of this project was to investigate the feasibility of using sorghum biomass to produce ethanol. The work performed included a detailed examination of the agronomics and composition of a large number of sorghum varieties, laboratory experiments to convert sorghum to ethanol, and economic and life-cycle analyses of the sorghum-to-ethanol process. This work showed that sorghum has a very wide range of composition, which depended on the specific sorghum cultivar as well as the growing conditions. The results of laboratory- and pilot-scale experiments indicated that a typical high-biomass sorghum variety performed very similarly to corn stover during the multi-step process required to convert biomass feedstocks to ethanol; yields of ethanol for sorghum were very similar to the corn stover used as a control in these experiments. Based on multi-year agronomic data and theoretical ethanol production, sorghum can achieve more than 1,300 gallons of ethanol per acre given the correct genetics and environment. In summary, sorghum may be a compelling dedicated bioenergy crop that could help provide a major portion of the feedstocks required to produce renewable domestic transportation fuels.
