The objective of this work was to determine the competitive interaction of sweet sorghum cultivars BRS 506, BRS509, and BRS 511 with biotypes of Alexandergrass and wild poinsettia. The adopted experimental design was the randomized block one, with four replications. Treatments were arranged in a substitution series by proportions of 100:0, 75:25, 50:50, 25:75, and 0:100%, corresponding to 20:0, 15:5, 10:10, 5:15 and 0:20 plant per pot of sweet sorghum (cultivars BRS 506, BRS 509 and BRS 511) withweeds (Alexander grass/wild poinsettia). The leaf area (LA) and dry matter (DM) of sweet sorghum, Alexandergrass and wild poinsettia plants were determined 50 days after emergence. Data about competitive abilities were analysed through the graphical analysis method, constructing diagrams based on yield or relative and total variations. Indices of relative competitiveness, clustering coefficient and aggressiveness were also determined; all of them were relative indices. There was competition for the same environmental resources between sweet sorghum cultivars and weeds, with mutual injury to the species involved in the community. Wild poinsettia and Alexandergrass negatively modified the LA and DM of the crop, demonstrating a greater competitive ability for the resources that are available in the environment. Wild poinsettia was less competitive than sweet sorghum cultivars, while Alexandergrass showed higher competitive ability than them. The highest losses for the LA and DM variables were observed when species were in interspecies competition rather than intraspecies competition.

The dependence on petrochemical resources and environmental and economic factors has intensified the search for cleaner and sustainable energy worldwide. Lignocellulosic biomass is a less polluting and renewable source of energy that can be explored in various industrial sectors (Fatma et al. 2018). In this context, biotechnological solutions for the production of renewable chemicals are under development as an alternative to processes based on fossil fuels. The lignocellulosic-biomass-derived sugars are the most abundant renewable feedstock available in the world and can come from different sources, such as agricultural and agribusiness residues, organic waste (food scraps), and forest residues (wood). These feedstocks lessen the need to expand farming areas, lowering the emission of gases that favor climate change. Lignocellulose is a component of the plant cell wall, a highly organized matrix that consists mainly of cellulose (40%?50%), hemicellulose (25%?30%), and lignin (15%?20%), in which proportions may vary depending on the plant species. Also, it may contain small amounts of other components, for example pectin, and inorganic compounds (Mathews et al. 2015; Bergmann et al. 2019). |
