Sorghum Bicolor L

Sweet sorghum (Sorghum bicolor L. Moench) contains fermentable sugars in the stem that can be converted to ethanol. The current study aimed at evaluating the performance of three sweet sorghum genotypes with five checks and contributes towards availing suitable sweet sorghum for industrial ethanol production. Field studies were carried out in Kenya at varied locations in a randomized complete block design with three replications. Sorghum was harvested at hard dough stage of grain development and evaluated for several stem juice production traits including plant height, cane yield, juice volume, degrees Brix, total, reducing, and non-reducing sugars, and ethanol yield via juice fermentation. Analyses of variance using SAS version 9.1 showed a significant effect of genotype for morphological characters and ethanol yield. Genotype EUSS10 produced the greatest cane (27.4 T/ha) and juice yield (7806.7 L/ha) whereas ACFC003/12 recorded the greatest ethanol yield (423.1 L/ha). At all sites, EUSS10 had the greatest plant height and days to 50% heading whereas SS04 had the greatest Brix and total sugar concentration. The greatest grain yield and non-reducing sugar concentration was produced by SS17 and SS21, respectively. Results of this study show that though Brix and total sugars are desirable for ethanol yield, cane yield, and juice volume of sweet sorghum determines the ultimate volume of ethanol produced.

Harvesting stage of sweet sorghum (Sorghum bicolor L. Moench) cane is an important aspect in the content of sugar for production of industrial alcohol. Four sweet sorghum genotypes were evaluated for harvesting stage in a randomized complete block design. In order to determine sorghum harvest growth stage for bioethanol production, sorghum canes were harvested at intervals of seven days after anthesis. The genotypes were evaluated at different stages of development for maximum production of bioethanol from flowering to physiological maturity. The canes were crushed and juice fermented to produce ethanol. Measurements of chlorophyll were taken at various stages as well as panicles from the harvested canes. Dried kernels at 14% moisture content were also weighed at various stages. Chlorophyll, grain weight, absolute ethanol volume, juice volume, cane yield, and brix showed significant (p=0.05) differences for genotypes as well as the stages of harvesting. Results from this study showed that harvesting sweet sorghum at stages IV and V (104 to 117 days after planting) would be appropriate for production of kernels and ethanol. EUSS10 has the highest ethanol potential (1062.78 l ha−1) due to excellent juice volume (22976.9 l ha−1) and EUSS11 (985.26 l ha−1) due to its high brix (16.21).

The genotype and environment interaction influences the selection criteria of sorghum (Sorghum bicolor) genotypes. Eight sweet sorghum genotypes were evaluated at five different locations in two growing seasons of 2014. The aim was to determine the interaction between genotype and environment on cane, juice, and ethanol yield and to identify best genotypes for bioethanol production in Kenya. The experiments were conducted in a randomized complete block design replicated three times. Sorghum canes were harvested at hard dough stage of grain development and passed through rollers to obtain juice that was then fermented to obtain ethanol. Cane, juice, and ethanol yield was analyzed using the additive main effect and multiplication interaction model (AMMI) and genotype plus genotype by environment (GGE) biplot. The combined analysis of variance of cane and juice yield of sorghum genotypes showed that sweet sorghum genotypes were significantly (P<0.05) affected by environments (E), genotypes (G) and genotype by environment interaction (GEI). GGE biplot showed high yielding genotypes EUSS10, ACFC003/12, SS14, and EUSS11 for cane yield; EUSS10, EUSS11, and SS14 for juice yield; and EUSS10, SS04, SS14, and ACFC003/12 for ethanol yield. Genotype SS14 showed high general adaptability for cane, juice, and ethanol yield.

 RESUMO - O rendimento de cultivares de sorgo sacarino em planta de primeiro corte e na rebrota tem sido estudado para viabilizar o cultivo com menores custos de produção. Entretanto, dados qualitativos sobre a qualidade de caldo e rendimento de etanol entre safra principal e rebrota são escassos. Objetivou-se com este trabalho comparar genótipos de sorgo sacarino quanto à qualidade industrial e avaliar o efeito do tipo de colheita e biomassa processada no rendimento industrial para produção de etanol. Foi conduzido um experimento em blocos ao acaso com três repetições em esquema de parcela subdividida, sendo as parcelas constituídas por 20 genótipos de sorgo e as subparcelas pelos tipos de amostras processadas ou colheitas realizadas. Os maiores rendimentos de etanol, em termos absolutos, foram obtidos para CMSXS646 e BRS 511 na colheita de primeiro corte com colmos limpos. A utilização de colmos limpos promoveu, em média, um incremento de 13,5, 14,2, 13,4, 3,3, 7,9, 7,0, 8,0 e 16,4% para etanol, ART, ATR, umidade, ARC, Pol, °Brix, quantidade de caldo, respectivamente, e redução de 17,3% para fibra, em relação às amostras de colmos com folhas. O rendimento médio de etanol por tonelada de caldo extraído foi 28% superior no primeiro corte comparativamente à rebrota.Palavras-chave: Bioenergia, biomassa, °Brix, Sorghum bicolor.  INDUSTRIAL QUALITY AND ETHANOL YIELD OF SWEET SORGHUM GENOTYPES IN MAIN AND RATOON CROPS  ABSTRACT - The yield of sweet sorghum cultivars in first cut and ratoon crops have been studied to enable the cultivation with lower production costs. However, qualitative data on broth quality and yield of ethanol on main crop and ratoon are scarce. The aim of this work was to compare sweet sorghum genotypes regarding the industrial quality and to evaluate the effects of harvests and processed biomass types in the industrial yield for ethanol production. A randomized block design experiment was carried out with three replicates in a split plot design, being the plots composed by 20 sorghum genotypes and the subplots by the types of processed samples or harvests. The highest ethanol yields, in absolute terms, were obtained for CMSXS646 and BRS 511 in first cut with clean stalks. The use of clean stalks promoted, on average, an increase of 13.5, 14.2, 13.4, 3.3, 7.9, 7.0, 8.0 and 16.4% for ethanol, ART, ATR, moisture, ARC, Pol, ° Brix, juice amount, respectively, and reduction of 17.3% for fiber, in relation to samples with stalks and leafs. The average yield of ethanol per extracted juice ton was 28% higher in first cut compared to ratoon.Keywords: bioenergy, biomass, °Brix, Sorghum bicolor.

Abstract A field experiment was conducted on sorghum (Sorghum bicolor (L.) Moench cv.) under three cutting system to determine the effect of nitrogen on growth and yield at University of Agriculture Faisalabad, Pakistan, during the season 2010-2011. The experiment was laid out in Randomized Complete Block Design (RCBD), using three replications. There were four levels of nitrogen 0, 50, 75 and 100 kg N/acre in the form of urea. The growth parameters like plant height, number of leaves, leaf area is determined periodically. First reading taken after 20 days of sowing while second and third was taken after 15 days of first cutting. Yield parameter like plant population, fresh and dry weight was determined in three cuttings. Results showed that increasing nitrogen dose increased all growth attributes. Results revealed for first, second and third cuttings showed significant differences at all growth attributes. Thus, the maximum plant height was observed in N4 (100 kg N/acre), having plant height 193.92, 195.24 and 192.79 cm in first, second and third cutting, respectively, which was followed by the treatment N3 (75 kg N/acre), having 179.70 cm in first cutting, while second and third cutting have same plant height 168.62 cm. The exception was the plant population showed non significant behavior in second and third cutting while number of leaves per plant in second cutting only and protein % in third cutting showed non significant difference with nitrogen application.

A study was carried out in two locations, Ilorin (8° 29′ N; 4° 35′ E; about 310 m asl) and Ejiba (8° 17′ N; 5° 39′ E; about 246 m asl), at the Southern Guinea Savannah agroecological zone of Nigeria to assess the effect of nitrogen fertilizer on the growth and ethanol yield of four sweet sorghum varieties (NTJ-2, 64 DTN, SW Makarfi 2006, and SW Dansadau 2007). Five N fertilizer levels (0, 40, 80, 120, and 160 kg ha−1) were used in a 4 × 5 factorial experiment, laid out in split-plots arrangement. The application of nitrogen fertilizer was shown to enhance the growth of sweet sorghum as observed in the plant height, LAI, CGR, and other growth indices. Nitrogen fertilizer application also enhanced the ethanol yield of the crop, as variations in growth parameters and ethanol yield were observed among the four varieties studied. The variety SW Dansadau 2007 was observed as the most promising in terms of growth and ethanol yield, and the application of 120 kg N ha−1resulted in the best ethanol yield at the study area.

&lt;p&gt;Terrestrial ecosystems worldwide are experiencing increasing atmospheric nitrogen (N) deposition because of fossil-fuel combustion and fertilizer applications. As a C&lt;sub&gt;4&lt;/sub&gt; feed crop, sweet sorghum (&lt;em&gt;Sorghum bicolor L.&lt;/em&gt;) is widely used in the arid region of China since its high sugar content, good palatability and high yield. However, impacts of atmospheric N deposition on production of sweet sorghum are poorly understood in arid land ecosystems where soils are typically low in plant available N. At Hui Autonomous Region, Ningxia, China, a complete random block design was used to study the effects of four levels of N additions (45, 169, 197, and 224 kg &amp;#8205;&amp;#8204;&amp;#8204;&amp;#8205;ha&lt;sup&gt;-1&lt;/sup&gt; year&lt;sup&gt;-1&lt;/sup&gt;) on sorghum, node number, stem diameter, leaf number, plant height, yield per plant, dry matter, and sugar Brix of stem. Nitrogen application significantly affected the above parameters. When the amount of N applied was 224 kg &amp;#8205;&amp;#8204;&amp;#8204;&amp;#8205;ha&lt;sup&gt;-1&lt;/sup&gt; year&lt;sup&gt;-1&lt;/sup&gt;, the plant height (mean &amp;#177; standard deviation, 256.9 cm &amp;#177; 10.7, n=9), stem diameter (16.9 mm &amp;#177; 1.1 ,n=9), number of leaf (10.8 &amp;#177; 1.3, n=6) and node (4.9 &amp;#177; 0.4, n=9), and dry matter per unit area (1.48 t ha&lt;sup&gt;-1&lt;/sup&gt; &amp;#177; 0.3, n=9) was highest. While N application did not affect sugar Brix of stem. Therefore, N deposition plays a linearly positive role in enhancing the productivity of sweet sorghum in the arid region of China.&lt;/p&gt;&lt;p&gt;Keywords: Agronomic traits, C&lt;sub&gt;4&lt;/sub&gt; plant, Feed crop, Nitrogen addition&lt;/p&gt;
