Biomass and sugar production dynamics in sweet sorghum variety Roger

Abstract

Sweet sorghum (Sorghum bicolor [L.] Moench) is a crop that is well known for its high production of biomass and sugars in the stem juice. The objective of this work was to evaluate the productivity of sweet sorghum 'Roger' based on the dynamics of sugar production and dry biomass by considering different production methods and plant phenological stages. The experimental design consisted of different tillage and fertilization methods established in a randomized complete block design with a split plot arrangement. Tillage treatments were assigned to the plot using the three levels of minimum tillage, traditional tillage, and traditional tillage that included a subsoil operation. Fertilization treatments were assigned to the subplot using the three levels of organic fertilizer, inorganic fertilizer, and without fertilizer. Data collection was performed at different plant phenological stages from anthesis to physiological maturity. Results showed that evaluated agronomic parameters depended on the phenological stage (P < 0.05) rather than the production methods (P > 0.05). Thus, the distribution and accumulation of sugar by stem internodes was associated with plant phenological components. The highest values of the concentration of total soluble solids (14.89%), juice sugar content (22.91 g), juice sugar concentration (527.46 mg g-1 DW), dry biomass (60.04%), and dry biomass yield (19.01 t ha-1) were observed at the physiological maturity stage of the plant.

High-Grade Chemicals and Biofuels Produced from Marginal Lands Using an Integrated Approach of Alcoholic Fermentation and Pyrolysis of Sweet Sorghum Biomass Residues

“…The biomass production on the marginal lands was rated to 40% of the production registered on optimal planting conditions of the envisaged hybrid. Analysis of the level of plant growth per square meter showed similar values regarding the biomass produced from the two crops, except that on the marginal lands the plants were smaller and thinner, and therefore had higher lignin content [49].…”

Characterization of New Sugar Sorghum Varieties (Sorghum Bicolor (L.) Moench) for Grain and Sugar Yield Under Two Growing Conditions in the Sudano-Sahelian Zone of Samanko, Mali

“…The sweet sorghum production showed its adaptability to both arable and marginal areas 5 . This crop can be processed as biofuel or valuable coproducts, while not affecting the production of grain as food, fuel, and fodder 6 . Also, Swet sorghum are mainly used for producing sorghum syrup 7 .…”
