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 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sweet sorghum (Sorghum bicolor L. Moench) is an important bioenergy crop. There is a wide array of genetic diversity in sweet sorghum germplasm collections. However, information on traits associated with sugar yield, optimum harvesting time for maximum sugar yield, effects of abiotic stresses on sugar yield is scarce. The objectives of the present study were: to identify traits that are associated with sugar yield, to determine the optimum harvesting time for maximum sugar yield and to understand the physiological responses of different sweet sorghum genotypes to drought and high temperature. In order to meet these objectives, five independent field and greenhouse studies were conducted. Field experiments were conducted using 280 sweet sorghum germplasm and were evaluated for 2 years. From this study, 30 genotypes representing high and low sugar yielders were selected for the subsequent experiment. We observed a significant variation in physiological, morphological and sugar yield traits associated with biofuel production. In the selection experiment, investigations on the morphological, physiological attributes helped to identify those characters which influence or limit sugar yield in the sweet sorghum. Another field study was conducted to optimize the harvesting time for obtaining highest sugar and juice yields in sweet sorghum. Sweet sorghum variety M81E was harvested at ten growth stages. Our results suggest that the optimum time for harvesting of sweet sorghum cultivar M81E is between milk and hard dough stages when highest sugar yield was observed. Studies on different levels of water stress were studied under greenhouse conditions. Four sweet sorghum genotypes (Awanlek, Smith, Tracy and Wray) were subjected to three water stress treatments (100% pot capacity (PC); 70% PC and 30% PC) for 20 days at early seed filling (Milk) stage. The results showed that genotypes differed significantly for all growth and yield, biochemical and physiological traits. Severe water stress significantly decreased juice and sugar yields by decreasing net photosynthetic rate, transpiration rate, stomatal conductance and sucrose content in the stem juice. Genotypes Tracy and Wray produced significantly highest brix, stem fresh weight, juice and sugar yield under both irrigated and water stress conditions. In another greenhouse study, we quantified the effects of drought, high temperature, and their combinations on growth, physiology and yield of sweet sorghum genotypes. The same four genotypes above were subjected to four treatments, T1 - control, T2 - drought stress, T3 - high temperature stress and T4 - combination of drought and high temperature for 16 days after anthesis. The result showed that significant difference was observed for growth and yield traits, physiological traits and non-reducing and total sugar content in juice for genotypes and treatments. Among the genotypes Tracy recorded higher juice and sugar yield. Among the various treatments, combination of drought and high temperature was found to be more deleterious in reducing most of the biofuel traits followed by drought and high temperature stress. The above studies gave significant findings with regards to the identification of superior sweet sorghum germplasm, their tolerance capacity to different abiotic stresses, which allows better selection for the use of bioenergy production.

This book was released on 1981 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifty-four sorghum (Sorghum bicolor (L.) Moench) genotypes were screened for differential response to N by growing plants with 10 mg N/ plant in nutrient solution. The genotypes TX 3934 X GH-8-17, and SC 423 X SC 239 produced the highest amount of dry matter per unit N (H), and SC 110 X SC 120, and SC 150-6 X SC 150-9 (L) produced the low-est amount of dry matter per unit N. Because of this, these genotypes were selected for further study to identify physiological properties that may be associated with differential N nutrition. The physiological properties evaluated in these genotypes were: (1) NO3 uptake rates as affected by time (hours after being put in a new N03 solution), N03 concentration, and plant age; (2) dry matter and N accumulation with plant age;(3) N distribution among plant parts at various plant ages; (4) dry matter produced per unit N; (5) genotype responses to different N levels and N compounds. Differential responses to N were moted among the genotypes screened with low N. The ranges were 131% for dry matter yields, 75% for N contents, 59% for top N/root N ratios, and 34% for dry matter produced per unit N. After an initial slow rate of N03 uptake, N03 absorption was relatively rapid during the next four hours before leveling off or decreasing after six hours in plants 34 days of age or younger; plants older than this showed no differences in N03 uptake. Patterns of N03 uptake with time suggested that uptake was induced by N03 at low concentrations. Differences in N03 uptake rates among (...).
Book Synopsis Plasticity of Sorghum Biomass and Inflorescence Traits in Response to Nitrogen Application by : Kyle M. Linders
Download or read book Plasticity of Sorghum Biomass and Inflorescence Traits in Response to Nitrogen Application written by Kyle M. Linders and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential nutrient required for growth and development in plants. Insufficient nitrogen availability can reduce vegetative growth and grain yield. However, nitrogen is a costly input for farmers, is energy intensive to manufacture, and runoff of excess nitrogen fertilizer impacts water quality. Compared to its close relative, maize, sorghum has much greater resilience to nitrogen and water deficit, and heat stress, allowing sorghum to be grown with fewer inputs and on marginal land. Variation in total biomass accumulation and grain yield between sorghum accessions, as well as between nitrogen conditions, can be largely explained by differences in vegetative growth and inflorescence architecture traits. Previous genome-wide association studies (GWAS) in sorghum have identified genetic markers associated with genes known to play roles in controlling growth and development. However, these studies have typically been conducted using field trials with “optimal” nitrogen application conditions. A set of 345 diverse inbred lines from the Sorghum Association Panel (SAP) were grown under both standard nitrogen application (N+) and no nitrogen application (N-) treatments, and a range of biomass and inflorescence-related traits were phenotyped, including plant height, lower and upper stem diameter, rachis length, lower and upper rachis diameter, and primary branch number. Stem volume, an approximation of biomass, was calculated from the directly measured traits. Stem volume was, on average, 10.48% higher for genotypes in nitrogen fertilized blocks, than for genetically identical plants in no nitrogen application blocks. Within individual treatment conditions, between 58.1% and 90.7% of the total variation for the measured and calculated traits could be explained by genetic factors. Genome-wide association studies were conducted to identify genetic markers associated with these traits in order to better understand the genetic factors involved in nitrogen stress response for potential use in breeding improved sorghum varieties.

Download or read book Sweet Sorghum and Nitrogen written by Khaled Miri and published by LAP Lambert Academic Publishing. This book was released on 2012-07 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sweet sorghum is versatile as a high value crop. Besides, bio-fuel, feed and fodder, it is very interesting for low cost and nutritious food . It has the potential of becoming a useful energy crop. It has been evaluated as an alcohol fuel crop with a promising future. This crop is attractive because of the easy accessibility of readily fermentable sugars combined with very high yields of green biomass suitable for production of more quantity of ethanol per unit time, per unit cost and per unit of water used . In India, it has been used for nearly 150 years to produce concentrated syrup with a distinctive flavor due to its characteristic of juicy stalks high in sugar. The ethanol production process is more Eco-friendly than that of sugarcane and its molasses (Morris, 2006). Nitrogen fertilizer combined with other inputs play crucial roles in yield and overall quality of sweet sorghum products. The present book is parts of studies which were conducted to determine suitable genotype and nitrogen level for higher productivity, nitrogen use efficiency and economic returns from sweet sorghum cultivation.

Download or read book Assesment of Sorghum Response to Nitrogen Availability written by Fatima Awada and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven accessions of Sorghum bicolor were grown with low (N−) and optimal (N+) nitrate supply. Growth parameters (plant height and leaf numbers), physiological parameters (nitrate, protein, total N and total C contents) and the activity of glutamine synthetase (GS) were studied in leaves and roots of sorghum plants at three time points of early vegetative growth (2, 4 and, 6 weeks post emergence). Plant height and leaf number were higher with nitrate supply. Except for carbon, all studied parameters were sensitive to N availability and values were typically lower when nitrate supply was low. However, different genotypes displayed considerable variation in their response to N regimes. Variation among genotypes during early vegetative development was observed for plant height, but not for leaf number. Likewise, physiological parameters varied among accessions. A significant and strong correlation, N- and accession-dependent, was detected between plant height and nitrate content. Moreover, nitrate content and GS activity at early growth stages appeared to be good markers to discriminate between nitrate uptake and assimilation capacities of different accessions under both N conditions. In some sorghum accessions, protein and total N content were indicative of high nitrate reduction and assimilation even under N limitation. Chlorophyll content was also sensitive to N availability. Furthermore, expression studies of SbNRT1.1gene copies in leaves and roots of two accessions reflected variability in expression dependent on nitrogen condition, plant organ, plant age, and gene of interest. This study is helpful to characterize different aspects of the N metabolism in sorghum and may aid in the identification of sorghum genotypes with enhanced nitrogen use efficiency, a trait that is of key interest in one of the most important crop plants in arid and semi-arid regions.

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.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Strategies to improve stem yield and juice quality in sweet sorghum were investigated in this study. Seed quality of sixty five accessions (landraces) from Botswana was investigated. Standard germination tests revealed that only 66% of the accessions had germination percentages in excess of 85%. The Accelerated Ageing test showed that only 50%of the 26 accessions had germination percentages above 80%. The results indicated that Botswana sweet sorghum seed quality is generally poor. Seed development and maturity observations demonstrated that maximum seed quality occurred 14 to 17 days after mass maturity (physiological maturity) and this coincided with maximum seed germination. These results suggest that harvesting sweet sorghum seed prior to mass maturity can lower seed quality. Farmers should, therefore be advised to select plants intended for seed harvesting and allow them to mature properly before the seeds are harvested. Differences in seed colour, shape and compactness of the inflorescences were observed amongst the 65 landraces collected from farmers in Botswana. Ten landraces were characterised and from the results it was evident that there was a range of genetic diversity which can be utilized in the improvement of the crop. Large panicles were characteristic of most sweet sorghum landraces, the effect of tiller, panicle and floret removal on juice quality was consequently studied. Removal of panicles and florets significantly improved juice quality whilst removal of tillers did not. Selection and breeding of genotypes with small panicles and male sterile varieties may improve juice quality and should be investigated. Effect of planting date, spacing and nitrogen were investigated. Early planting (October) resulted in increased stem yields but reduced juice quality. A 30 cm intra-row spacing resulted in high stem yields per plant and good juice quality. Nitrogen fertilisation increased stem yield and improved juice quality. On the bases of the results obtained from this study, early planting (October), application of 60 kg N ha-?, and 30 cm intra-row spacing could be recommended for sweet sorghum production in pure stands. In pure stands yields of more than 37 000 stems (per hectare) of good quality can be attained. These could be sold at an estimated price of P2.00 (R2.25) per stem indicating the potential of sweet sorghum as a cash crop. However, its economic viability depends on the price elasticity in the supply - demand function.
