There is little information about the effects of ethephon ripening hormone on the yield of sweet sorghum in Thailand. Therefore, this study aimed to evaluate the impact of ethephon hormone applied at different growth stages of three cultivars of sweet sorghum on its growth and yield. The experiment was conducted from December 2016 to May 2017 at a research plot of the Faculty of Agricultural Technology, King Mongkuts Institute of Technology Ladkrabang, Bangkok, Thailand. The experiment was designed as a split-plot design with three replications. Three sweet sorghum cultivars (Ethanol 2, KKU 40, and Cowley) were planted in the main plot. Ethephon was applied at five stages of growth of these cultivars: heading stage, panicle stage, milking stage, dough stage, harvesting stage. Ethephon applications at those stages and untreated control were the subplots. Results showed that Ethanol 2 cultivar exhibited a higher growth rate, plant height, stem diameter, grain yield, stem fresh weight, and yield, juice
Sweet sorghum is characterized by high sugar content and high biomass and is of growing interest to the biofuel industry. For sweet sorghum to be successfully used for bioenergy production, genetic relationships and diversity within sweet sorghums should be better understood, genetic and physiological mechanisms that distinguish sweet from non-sweet sorghums need to be characterized, and higher-yielding sweet sorghum female lines are needed to create sweet hybrids with higher sugar yields. Each of these needs is addressed in a separate chapter of this thesis. The first chapter describes the characterization of genetic differences among sweet sorghum cultivars and diverse landraces of sorghum. Genotyping-by-sequencing (GBS) was conducted on more than 700 sorghum lines to generate genome-wide single nucleotide polymorphism (SNP) data and assess population genetic differences between groups. The genomic region of highest genetic differentiation (FST) between sweet and landrace sorghums contains a ...
Sweet sorghum accumulates high concentrations of fermentable sugars in the stem, produces significant amount of starch in the grain (panicle) and has shown to be a promising energy feedstock. Sweet sorghum has a short growing season so adding it to the sugar cane system would be good. The overall goal of this dissertation is to enhance the attractiveness of biofuel production from sweet sorghum to fully utilize fermentable sugars in the juice, starch in the panicle and structural carbohydrates in the stalk for high efficiency and low-cost ethanol production. Sweet sorghum juice was incorporated into the dry-grind process which achieved 28% increase of ethanol yield compared to the conventional ethanol method and decreased enzymatic hydrolysis time by 30 minutes. A very high gravity fermentation technique was applied using sweet sorghum juice and sorghum grain yielded 20.25% (v/v) of ethanol and 96% fermentation efficiency. Response surface methodology was applied in order to optimize diffusion ...
Milo or grain sorghum (Sorghum bicolor) is adapted for Kentucky but is not widely grown. Grain sorghum is an option for fields that tend to dry slowly in the spring and require later planting dates that are more suited to sorghum than to corn. Grain sorghum is more drought tolerant than either corn or soybean, making it a viable option for fields that are prone to drought. Grain sorghum uses less nitrogen than corn and will produce similar yields to corn on marginal soils. Some people are interested in sweet sorghum (Sorghum bicolor) which is the same species as grain sorghum, but a different growth type. With sweet sorghum, the sap is extracted from the stalks of the plants and that sap is refined into sorghum syrup. For more information on sweet sorghum, click here.. ...
The ability of Saccharomyces cerevisiae to ferment sweet-stalk sorghum juice depend on the strains of the yeast and sweet sorghum cultivars used in the fermentation process. This research was aimed to evaluate the ethanol production capability of eight yeast strains using sweet-stalk sorghum juice from three sweet sorghum cultivars as a source.. Yeast strains used for ethanol fermentation were OUT 7009, 7027, 7096, 7055, 7921, 7080, and 7903. Sweet-stalk sorghum juice extracted from three cultivars of sweet sorghum (FS501, FS902 and KCS105) with addition of 4,60 g/l (NH4)2SO4 and 0,45 g/l KH2P04 were used to observe the growth and fermentation ability of the yeast strains in batch culture. Yeast extract peptone dextrose (YEPD) broth were used as a standard medium for aerobic growth of the yeast strains. The sugar brix content of the sweet-stalk sorghum juice were measured using refractometer (ASONE, Spittz IPR-101α) and the sugar profile were evaluated by HPLC. Yeast specific growth rates were ...

The regions of north-eastern Ethiopia are known for their high levels of sorghum genetic diversity, and for being drought prone. For centuries, sorghum has been developed and maintained by farmers for its adaptation to the marginal and heterogeneous environment of these regions. The objective of this study was to examine the genetic diversity and population structure of 200 sorghum landraces collected from seven lowland districts, using 30 microsatellite markers sampled from all linkage groups of the sorghum genome. Both distance-based and model-based analytical approaches were used to analyse the data. The data analysis revealed that there was a large variation among all the markers under study. The values of polymorphic information content ranged from 0.26 to 0.88, with a mean value of 0.61, reflecting the high discriminating ability of the markers studied. The mean value of total gene diversity was 0.69, which partitioned 86% among the landraces and 14% within the landraces. Gene diversity ...

The two-step enzymatic hydrolysis of sweet sorghum and cassava were performed by commercially available α-amylase and glucoamylase and further ethanol fermentation of the obtained hydrolyzates by Saccharomyces cerevisiae were studied. For both sweet sorghum and cassava, the hydrolysis and fermentation were done in a 2 L stirred tank bioreactor, B-Braun fermenter, by using the same conditions. The amount of glucose obtained after hydrolysis process was greater in sweet sorghum compared to cassava, which are 50.07 and 40.00 g L-1, respectively. Also, sweet sorghum gave higher ethanol concentration than cassava at the 64 h of fermentation process, which are 40.11 and 34.07 g L-1, respectively.. ...

TY - JOUR. T1 - Improved production of ethanol using bagasse from different sorghum cultivars. AU - Nasidi, Muhammad. AU - Agu, Reginald C.. AU - Deeni, Yusuf Y.. AU - Walker, Graeme M.. PY - 2015/1/1. Y1 - 2015/1/1. N2 - For improved production of ethanol from whole sorghum residues, physico-chemical compositions and fermentation characteristics of the substrates are important factors to consider. In the present study, Nigerian sorghum cultivars SSV2, KSV8 and KSV3 were grown under rain-fed conditions without chemical fertilization in Kano state, Nigeria. On harvest, the whole sorghum residues (bagasse) comprising crushed stalks, leaves, panicles and peduncles were collected for further processing. Bagasse samples, which had different macromolecular composition and carbohydrate pasting properties, were pre-treated with dilute sulphuric acid at 75 °C followed by enzymatic hydrolysis and sequential detoxification by Ca(OH)2 over-liming and charcoal filtration. Hydrolysate samples were ...
The rising demand for bioethanol, the most common alternative to petroleum-derived fuel used worldwide, has encouraged a feedstock shift to non-food crops to reduce the competition for resources between food and energy production. Sweet sorghum has become one of the most promising non-food energy crops because of its high output and strong adaptive ability. However, the means by which sweet sorghum stalks can be cost-effectively utilized for ethanol fermentation in large-scale industrial production and commercialization remains unclear. In this study, we identified a novel Saccharomyces cerevisiae strain, TSH1, from the soil in which sweet sorghum stalks were stored. This strain exhibited excellent ethanol fermentative capacity and ability to withstand stressful solid-state fermentation conditions. Furthermore, we gradually scaled up from a 500-mL flask to a 127-m3 rotary-drum fermenter and eventually constructed a 550-m3 rotary-drum fermentation system to establish an efficient industrial fermentation
Last month, Ceres announced that it has signed a sweet sorghum market development agreement with Syngenta. The companies will work together to support the introduction of sweet sorghum as a source of fermentable sugars at Brazils 400 or more ethanol mills.. Last season, Brazilian mills planted Ceres sweet sorghum on more than 3,000 hectares (7,400 acres). The trials demonstrated large increases in biomass, extractable juice volume and total harvestable sugar compared to commercial products introduced just last year. In product development trials and at the companys breeding center, where field evaluation plots are irrigated and managed more closely than commercial fields, these hybrids averaged 80 or more metric tons per hectare. Subsequent field evaluations in the Southeast U.S. this summer have confirmed similar results.. READ MORE: All about the project, here. ...
This study was conducted to evaluate traits that have an effect on yield, and genetic variation for these traits, including dry matter accumulation, remobilization, and traits associated with them, in 10 grain sorghum genotypes obtained from the National Plant Gene Bank of Iran under moisture stress conditions. Field trials were carried out in the 2008 cropping season using split-plot arrangements in a randomized complete block design with three replications at Torogh Agricultural Research Station of the Agricultural and Natural Resource Research Center of Khorasan Razavi Province, Mashhad, Iran. Trials were conducted separately under three water regimes: normal conditions and two water deficit levels at the vegetative and reproductive stages. Genotypes were assigned to main plots and two levels of photosynthetic status, normal and disturbed current photosynthesis, by applying potassium,iodide after anthesis, in sub-plots. Results revealed significant genetic variation for traits related to dry matter
Sorghum (Sorghum bicolor) grain contains many health-promoting phytochemicals, including a broad range of phenolic compounds. Malting of cereal grains is known to increase the bioavailability of macro- and micronutrients. However, the detailed effects of malting on sorghum grain anthocyanins, a major class of phenolics that influence the taste and colour of sorghum-based foods, requires further investigation. Eight commercial sorghum hybrids harvested from three regions in eastern Australia were malted and analysed for colour, tannin content, total phenolic content (TPC), flavan-4-ols, total flavonoids, total anthocyanins and 3-deoxyanthocyanins. Grains of all the sorghums were found to be tannin-free. Malting decreased the TPC of all samples. For TPC, the grand means among all the sorghum cultivars for raw and malted grain were 2.77 and 2.48 mg gallic acid equivalents (GAE)/g, respectively. For flavan-4-ols, the grand means for raw and malted sorghum grains were 2.98 and 2.23 abs/mL/g, respectively.
Biomass based alternative fuels offer a solution to the worlds ever-increasing energy demand. With the ability to produce high biomass in marginal lands with low inputs, sorghum has a great potential to meet second-generation biofuel needs. Despite the sorghum crop importance in biofuel and fodder industry, there is no comprehensive information available on the cell wall related genes and gene families (biosynthetic and modification). It is important to identify the cell wall related genes to understand the cell wall biosynthetic process as well as to facilitate biomass manipulation. Genome-wide analysis using gene family specific Hidden Markov Model of conserved domains identified 520 genes distributed among 20 gene families related to biosynthesis/modification of various cell wall polymers such as cellulose, hemicellulose, pectin and lignin. Chromosomal localization analysis of these genes revealed that about 65% of cell wall related genes were confined to four chromosomes (Chr. 1-4). Further, 53
Sugarcane aphids were observed infesting sorghum in Louisiana, Mississippi, Texas and Oklahoma in 2013, LSU AgCenter entomologist David Kerns said. This pest also has been found in johnsongrass, sweet sorghum and sorghum-Sudan, Kerns said. The pest was detected in 38 counties and parishes in the four states. Aphids also were found in one state in Mexico, and Arkansas may be infested, Kerns said. The sugarcane aphid is a significant pest of sorghum in China, Taiwan, Japan, India, South Africa, South America, Botswana and Zimbabwe. It has been found infesting sugarcane in Louisiana since 1999. There was one unconfirmed report of an infestation in Louisiana sorghum in 2008. Infestations also were found in sorghum beginning in mid-July 2013. Kerns said it is not known why the pest shifted from sugarcane to sorghum. It is interesting that in places where there were heavy infestations of sugarcane aphids in sorghum in 2013, the aphid was not found in nearby fields of sugarcane, energycane or Sudan ...
Holstein cows in early lactation were utilized to evaluate the effects of supplementing concentrate diets of sorghum grain on milk production, milk composition, somatic cell count, and body condition. At 21 d postpartum, cows were randomly assigned to receive four concentrate diets consisting of 1) corn, 2) sorghum, 3) sorghum plus 1 lb tallow, and 4) sorghum plus wheat in a 70:30 ratio. All concentrates were combined with chopped alfalfa hay in a total mixed diet and fed twice daily. Treatments included a 7-day preliminary period and a 16-week experimental period. Cows fed the sorghum plus tallow diet produced 14% more milk than cows fed either corn or sorghum alone and 10% more than cows fed the 70:30 sorghum plus wheat diet. Milk fat was unaffected by diet, although cows receiving the sorghum plus wheat diet tended to produce milk with less fat (3.3% vs 3.5% for the other diets). Body weight and body condition tended to be higher for cows fed the sorghum plus wheat combination. The addition ...
Fractions from white and tannin sorghums were processed into extrudates, thick porridges, and breads. The effects of sorghum type and fraction on the in vitro starch availability of the products were evaluated, and the estimated glycemic indexes (EGI) of the products were obtained. Sorghum extrudates were significantly more slowly digested than corn meal extrudates for all preparation methods (whole, cracked and decorticated kernels). Furthermore, tannin extrudates were less digestible than white sorghum extrudates. The soft endosperm nature of the tannin sorghum limited friction formation inside the extruder, reducing starch gelatinization. On the other hand, condensed tannins also interfered with the starch availability for digestion. White sorghum was more suitable for extrusion, giving extrudates with higher starch degradation and expansion than the tannin sorghums. However, tannin sorghums also gave acceptable products offering the benefit of lower EGI values. Sorghum porridges were more ...
Scope and method of study: To study the plant cell wall degradation process and changes in overall physiology during the growth of A. nidulans on sorghum stover at proteomic and genomic level, A. nidulans was grown on sorghum stover under solid-state culture conditions for 1, 2, 3, 5, 7 and 14 days. Semi-quantitative extracellular proteome analysis (1-D PAGE LC-MS/MS), whole genome microarray analysis, scanning and transmission electron microscopy, along with qualitative and quantitative analysis of extracellular hydrolytic enzyme activities, and analysis of the breakdown products by enzymes was used to study sorghum cell wall degradation by A. nidulans.Findings and conclusions: Based on analysis of chitin content, A. nidulans grew to be 4-5% of the total biomass in the culture. A hyphal mat developed on the surface of the sorghum by day one and as seen by scanning electron microscopy the hyphae enmeshed the sorghum particles by day 5. A total of 294 extracellular proteins were identified with ...
Author】 WANG Donghai1, and WU Xiaorong2 1 Biological and Agricultural Engineering, Kansas State University, Manhattan, KS 66506, USA 2 Postdoctoral Research Associate, Biological and Agricultural Engineering, Kansas State University, Manhattan, KS 66506, USA. 【摘要】 Dry land crops such as sorghums (grain sorghum, sweet sorghum and forage sorghum) have been identified as promising feedstocks for fuel ethanol production. The major issue for using the sweet sorghum as feedstock is its stability at room temperature. At room temperature, the sweet sorghum juice could lose from 40% to 50% of its fermentable sugars from 7 to 14 days. No significant sugar content and profile changes were observed in juice stored at refrigerator temperature in two weeks. Ethanol fermentation efficiencies of fresh and frozen juice were high (~93%). Concentrated juice (≥25% sugar) had significantly lower efficiencies and large amounts of fructose left in finished beer; however, winery yeast strains and novel ...

The latest USDA crop update released July 7, 2015, indicated 97 percent of the nations grain sorghum has been planted, slightly behind the 5-year average. Heading was 24 percent complete by July 5 and harvest has begun in some areas of South Texas. As a whole, 67 percent of the sorghum crop was reported good to excellent, six percentage points better than last year at this time.. TEXAS - Texas is 99 percent completed planting grain sorghum, 56 percent of which is headed. Producers across the southern regions of the state have begun harvest on irrigated sorghum this week and will continue harvest into next week. Danny Beyer of Odem, Texas, said early planted sorghum currently being harvested is achieving impressive yields, as high as 125 bushel on small blocks. Despite lower ground being saturated by earlier rains, Beyer said the sorghum crop across the coastal bend is progressing well. Overall, 63 percent of grain sorghum across the state is in good to excellent condition and producers are ...
EPA Approves Grain Sorghum Pathway - The Environmental Protection Agency (EPA) announced yesterday it has approved grain sorghum as an eligible feedstock under the Renewable Fuel Standard (RFS). National Sorghum Producers (NSP) has worked closely with EPA for about three years in getting grain sorghum listed as an advanced biofuel feedstock, and the feat has finally been won. The RFS requires a certain amount of feedstocks to be used to produced advanced biofuels. With sorghums listing, it will now create a significant amount of domestically-grown sorghum that needs to be used to produce ethanol. This use, in turn, will add value and profitability to the producers crop. This gives an incentive to the ethanol plants to use sorghum when producing their biofuels. EPA found that, when plants use sorghum to create ethanol at facilities that use natural gas, they have a greenhouse gas (GHG) emissions reduction of 32 percent, qualifying it as a conventional ethanol. NSP expects at least one existing ...
The project to produce ethanol from sweet sorghum undertaken by the International Crops Research for the Semi-Arid Tropics (ICRISAT) and Rusni Distilleries, both of India had achieved a breakthrough in their first production of ethanol flowing out the distillery.. The production itself works a milestone in the partnership project. It has generated ethanol as biofuel. The stems of sorghum yield sweet juice that could be processed into bioethanol which could be added to gasoline. The production of ethanol does not compromise food security since the farmers can continue to use the grain for food.. The juice could also be made into syrup, wine and vinegar. The grains can be milled and made into a variety of delicacies. Whole grains can be fed and milled as ingredient in commercial feeds for livestock and poultry. This also serves an additional income to farmers who are looking for a crop that will grow well in drought prone areas.. Growing sweet sorghum has its distinct advantage over other crops ...
Sweet sorghum stalks were used as a low cost carrier for immobilization of Saccharomyces cerevisiae NP 01 to produce ethanol from sweet sorghum juice. The effects on ethanol production of carrier size (6 × 6 × 6 to 20 × 20 × 20 mm3) and initial cell concentrations (5 × 107 to 2 × 108 cells mL−1) for cell immobilization were investigated. The ethanol production medium was the juice containing 230 g L−1 of total sugar without nutrient supplementation. The fermentations were carried out under static conditions in 500-mL air-locked Erlenmeyer flasks at 30 °C. The results showed that the optimum size of sorghum stalk pieces for repeated-batch ethanol production was 6 × 6 × 6 mm3, while the optimum initial cell concentration for the immobilization was 1.0 × 108 cells mL−1. The immobilized yeast under these conditions could be used for at least eight successive batches without any losses of ethanol production efficiencies. The average ethanol concentration, productivity and yield of the eight
June 2017. Sorghum is one potential ingredient to substitute for cassava as a source of starch for feeding Pangasius in Vietnam. Sorghum contains a reasonable amount of protein (10%), higher than cassava. Sorghum contains higher amino acids, similar to corn but relatively higher in tryptophan and threonine. The U.S. Grains Council (USGC) conducted a sorghum feeding trial to Pangasius catfish at research farm of a private company in Vietnam. The sorghum diet was compared to a cassava-based diet and corn-based diet. Grain sorghum was obtained from the United States and was analyzed for chemical composition and amino acids content. Researchers allotted 2,160 Pangasius fingerling at 25 g body weight randomly in 12 floating cages made of nylon net placed in 0.5- hectare pond with 3 meters deep. The cages were divided into three groups of dietary treatments and replicated 4 times. Three dietary treatments were used containing cassava 15%, sorghum 20% and corn 10% in the diets respectively. The diets ...
In Vitro Effect of Sorghum (Sorghum bicolor) Seed Extracts as a Biological Acaricidal Against Some Hard Tick (Ixodidae) in Sulaimani Governorate - Kurdistan Region/Iraq
Sorghum and maize grain hardness is a very important criterion as grain hardness affects milling yield and product quality. There are several techniques that are used to determine grain hardness but the relationship between these techniques for distinguishing hardness in commercial sorghum and maize cultivars is not known. Moreover, the role of sorghum grain hardness with respect to malting performance is not understood, as is the role of phenolics in sorghum and maize hardness. Therefore this study investigated the relationships between sorghum and maize hardness techniques, and the influence of sorghum grain modification during malting and sorghum and maize phenolics on the hardness of these cereals. A study to determine the relationships between techniques used to measure hardness in commercial sorghum and maize cultivars was done in terms of decortication using the Tangential Abrasive Dehulling Device (TADD) (percentage kernel removed), Near Infrared Transmittance (NIT) Milling Index (MI), ...
In Washington, D.C., the U.S. Grains Council reports that recent sales of U.S. sorghum to Spain and Italy reinforce the importance of these European markets to U.S. farmers. Italy purchased 36,600 metric tons (1.44 million bushels) of sorghum the week of March 14, and Spain has purchased just under one million tons (39.4 million bushels) of sorghum since April 2018.. A combination of factors has resulted in the return of these two buyers to the sorghum market this marketing year. In addition to ample supply of U.S. sorghum, a drought in Europe has driven up the price of European feedstock. U.S. sorghum is an attractive alternative with duty-free access to the market and no biotechology-related concerns.. The Council worked with Spanish buyers last spring by bringing sorghum sellers to Spain and conducting two purchasing conferences, resulting in purchases of diverted shipments from China. These activities paved the way for renewed interest in U.S. sorghum, and the Spanish have continued to ...
Its water requirement is one-third that of sugarcane, and its growing period is short enough to allow harvesting twice a year. While sugarcane is propagated from stem cuttings, sweet sorghum is sown with seed - just 4.5 kg is enough for a hectare of land, compared to 4,500-6,000 kg of sugarcane cuttings." Sweet sorghums potential as an energy crop - it produces up to 7,000 litres of ethanol per hectare - makes it highly attractive for countries like China [and the US], which is expected to exhaust its economically recoverable petroleum reserves by 2016. __Source ...
Increased fossil fuel consumption has resulted in a series of social and environmental problems, such as the crisis of oil, global climate change and the emission of greenhouse gas. Sustainable and clean renewable energy as an alternative to fossil fuels has attracted extensive attention worldwide. Among various renewable energies, bioethanol is an important renewable liquid fuel due to its high octane number and heat of vaporization. Bioethanol is also less volatile than gasoline, has a lower photochemical reactivity in the atmosphere, and smog formation from emissions of pure ethanol can be less than from gasoline [1].. Sweet sorghum is a high photosynthetic-efficiency energy crop with high biomass (20 to 30 dry tonnes/ha) and sugar-yielding (16 to 18% fermentable sugar in juice) [2]. It is also the only crop that provides grain and sugar, and a lignocellulosic biomass resource. Sweet sorghum has several primary advantages, such as (1) its adaptability to diverse climate zones and soil ...

A study was conducted in Sudan (Africa) during the summer and winter seasons (2013 – 2014) at two locations: Shambat (normal soils) and Soba (salt affected soils). Nine maize (Zea mays L.) and sorghum (Sorghum bicolor (L.) Moench) cultivars were studied under two watering regimes arranged in split plot experiment in randomized complete block design. The eight test-environments created by the combination of locations, seasons and watering regimes were used to investigate the effect of salt, water and heat stresses on forage yield and some related traits. The results showed that separate and combined stress factors significantly reduced forage yield. The greatest reduction in dry matter yield caused by one factor was shown by salt stress (29.6%) and the least reduction was caused by heat stress (3.9%). Water stress coupled with either heat or salt stress caused the greater reduction in yield (37.0%-43.3%) than the combination of the other factors. Full stress caused 53.8% yield reduction. Days to

This study examines the economic potential of producing a wheat (Triticum aesitivum) and grain sorghum (Sorghum bicolor (L.) Moench) rotation with three different tillage strategies compared to the Conservation Reserve Program (CRP) in a semi-arid region. This research uses stochastic efficiency with respect to a function (SERF) to determine the preferred management strategies under various risk preferences and utility-weighted certainty equivalent risk premiums. Yields, input rates, and field operations from an experimental field in western Kansas are used to calculate net returns for each tillage strategy. Although current net returns to crop production using reduced tillage and no-tillage strategies are higher than CRP, risk analysis indicates CRP would be the preferred strategy for some risk-averse managers.

One species, Sorghum bicolor,[10] native to Africa with many cultivated forms now,[11] is an important crop worldwide, used for food (as grain and in sorghum syrup or "sorghum molasses"), animal fodder, the production of alcoholic beverages, and biofuels. Most varieties are drought- and heat-tolerant, and are especially important in arid regions, where the grain is one of the staples for poor and rural people. These varieties form important components of pastures in many tropical regions. S. bicolor is an important food crop in Africa, Central America, and South Asia, and is the fifth-most important cereal crop grown in the world.[12]. Some species of sorghum can contain levels of hydrogen cyanide, hordenine, and nitrates lethal to grazing animals in the early stages of the plants growth. When stressed by drought or heat, plants can also contain toxic levels of cyanide and/or nitrates at later stages in growth.[13]. Another Sorghum species, Johnson grass (S. halapense), is classified as an ...

... is the fifth most important cereal crop in the world in terms of production and harvested area. This drought-tolerant crop is grown on 45 million hectares, with 75% of the area concentrated in ten countries: Sudan, India, Nigeria, Niger, USA, Mexico, Ethiopia, Burkina Faso, Mali and Chad. Sorghum is a staple crop in Asia and Africa, and is grown for both food and industrial purposes.. Sorghum cultivation emerged with cattle herding as an adaptation to the dry conditions of the Sahel. The earliest archeological evidence of the use of sorghum by humans is dated at about 9000 BP, and was found in the border between Egypt and Sudan. Sorghum has been used as a model to study the influence of cultural factors in shaping the genetic composition and the geographical distribution of crops. This is particularly relevant to understand how traditional seed-exchange systems work, and therefore to find efficient ways to diffuse improved varieties.. The global strategy for the ex situ conservation of ...

European Journal of Plant Pathology. 136 (3): 469-481. Interpretive Summary: Fluorescent Pseudomonas bacteria were collected from roots and associated soil of different sorghum cultivars and a wheat cultivar grown in two different soil types. The ability of the bacteria to produce compounds that inhibit fungi that cause diseases in sorghum was determined. Results indicated that both soil type and plant cultivar affected soil bacteria populations that can inhibit sorghum pathogens. Two bacterial isolates or strains found on the sorghum roots and associated soil inhibited the growth of five pathogens. These two isolates have potential as biological control agents for sorghum fungal pathogens. Technical Abstract: Sorghum is used as bioenergy feedstock, animal feed, and food. Economical methods for disease prevention and control ...
