Qualidade Do Caldo Para Produção De Etanol Em Cultivares De Sorgo Sacarino Sob Adubação Nitrogenada

Abstract

RESUMO -O sorgo sacarino tem potencial de uso como fonte de matéria-prima para a produção de bioetanol.Objetivou-se, com este estudo, analisar o efeito da adubação nitrogenada de cobertura na qualidade do caldo para QUALITY OF BROTH FOR ETHANOL PRODUCTION IN CULTIVARS OF SACARINE SORGHUM UNDER NITROGEN FERTILIZATIONABSTRACT -Sweet sorghum has potential as a source of raw material for the production of bioethanol. The objectiveof this study was to analyze the effect of nitrogen topdressing on the quality of the juice for ethanol production from four cultivars of sorghum. The experiment was conducted in Campos, State of Rio de Janeiro, Brazil, from January to May 2014. Four cultivars of sorghum: BRS 506, BRS 508, BRS 509 and BRS 511 were studied, and five nitrogen rates

Selectivity of Herbicides Applied Alone and in Tank Mixtures to Sweet Sorghum in Post-Emergence

“…The crop has a short developmental cycle, tolerance to drought periods, high biomass production and high sugar content in the stalks (Teixeira et al, 1999). In addition, it represents an excellent alternative for bioenergy production as it presents desirable agronomic characteristics for the sugar and alcohol industries, as it allows its use in the sugarcane off-season and its implantation and harvesting is fully mechanized (Albuquerque et al, 2012;Solano et al, 2017).…”

Herbicide Selectivity in Preemergence of Sweet Sorghum Cultivated in Different Soil Texture

“…Sweet sorghum (Sorghum bicolor (L.) Moench) has been shown to be an excellent alternative for biomass and ethanol production, as it presents agronomic characteristics that are adapted to the needs of this industry sector, optimizing industrial production plants, since it can be used in the off-season of sugarcane and due to its fully mechanized implantation and harvesting (Albuquerque et al, 2012;Solano et al, 2017). Among the agronomic characteristics of interest, it is possible to highlight the short development cycle, tolerance to dry periods, high biomass production, high adaptation to the existing agricultural infrastructure and considerable levels of sugars in the stalks, which allows it to be cultivated throughout the country (Appiah-Nkansah et al, 2019;Maciel et al, 2017;Martins et al, 2017).…”
