![]() ![]() Petroleum prices have made alternative fuel crops a viable option for ethanol production. ![]() Finally, a method to measure the fermentable sugars was developd using the Technicon Autoanalyser II.Įvaluation of sweet sorghum as a potential ethanol crop in Mississippi Application of several growth regulators such as Gibberellin didn't significantly increase the yield of sugars. The best weed control was achieved by treating with Propazine plus Metolacheor. The fertility needs of sweet sorghum appear to be relatively low and the yield response to applications of N, P, K are given. To justify the operation of an ethanol plant, sweet sorghum should be harvested over a period of months, so cultivars were selected for yearly, medium and late maturity, thus ensuring a constant supply of feedstock over a four month period. Wray was the best cultivar, producing a high sugar per hectare. Field experiments were designed over three years to study several aspects of the production of fermentable sugars from sweet sorghum and these included cultivar types, fertility needs, weed control and growth regulation. Studies were undertaken on the southern coastal plain (Georgia) of the USA on sweet sorghum to evaluate its potential as a fuel ethanol feedstock. Growing sweet sorghum as a source of fermentable sugars for energyĮnergy Technology Data Exchange (ETDEWEB) The purpose of this study was to compare five inbred sweet sorghum lines and 15 hybrids derived from them, and to determine the extent of envir. Sweet sorghum ( Sorghum bicolor (L.) Moench) has potential as a biofuel feedstock but hybrid cultivars are needed to support an industry based on this crop. The environment strongly affects estimates of heterosis in hybrid sweet sorghum Keywords: Sweet sorghum, Stem yield, Sucrose percentage, Harvesting stages On the basis of the results obtained, 400 thousand plant/ha plant density, Keller cultivar and hard dough harvest stage might be suitable for sweet sorghum production under the condition similar to the present study. Maximum stem fresh weight, juice yield, sucrose percentage and purity were obtained at hard dough harvest stag. There were no significant difference between two cultivars for sucrose percentage and purity but sucrose percentage in Keller had highest as compared to Rio. Number of tiller per plant of Rio was significantly more than Keller. Keller was significantly superior for plant height, stem diameter, stem fresh weight, juice yield and brix at hard dough harvest stage as compared to Rio. The highest juice yield and purity were produced by 400 thousand plants/ha. The effect of plant density at hard dough harvest stage on plant height, stem diameter, number of tillers, stem fresh weight and juice yield were significant but had no significant effect on brix, sucrose percentage and purity. Main plots were plant densities (100, 200, 300, 400, 500 and 600 thousand plant/ha and subplots were cultivars (Rio and Keller. A split plot layout within a randomized complete block design with tree replication was used. Two hybrid cultivars, Zaoshu-1 (ZS 1) and Chuntian-2 (CT 2), and twoĮffect of Increase in Plant Density on Stem Yield and Sucrose Content in Two Sweet Sorghum Cultivarsįull Text Available Abstract In order to evaluate the effect of increase plant density on stalk yield and sucrose content in two sweet sorghum cultivars, an experiment was conducted at Research Farm of Isfahan University located at Zaghmar village. Xie, G.H.Įffects of cultivar choice and nitrogen supply on biomass yield and dry matter partitioning of sweet sorghum were studied under irrigated conditions in the arid temperate climate of north-west China. Sweet sorghum performance under irrigated conditions in northwest China : Biomass and its partitioning in inbred and hybrid cultivars at two nitrogen levelsįan, F. In the production of ethanol per tonne of biomass (EP, the cultivars BRS508 and CMSX629 presented the best results. Regarding the sugar content, the cultivars BRS508, XBWS80147 and CMSX629 showed the highest means for the total reducing sugars (TRS and recoverable sugar (RS. The results showed a significant difference between cultivars and harvest dates for all parameters analysed (p≤0.01. This work aimed to develop and study the maturation curves of seven sweet sorghum cultivars in ten harvest dates. Due to this fact, there is a need for the analysis of sweet sorghum properties in order to meet the agro-industry demand. for the production of ethanol, since it has juicy stems with directly fermentable sugars.
