Abstract

Weeds are responsible for decreasing the productivity of different agricultural crops. Due to the importance of the topic, the objective of this research was to evaluate how the community of native and exotic invasive harmful plants is structured in cassava plantation areas on rural properties in the region of Itabaiana, SE. For this, five areas were selected and 10 plots of 1 m² in each area were shown. In the units shown, all the individuals of each species present were counted, and for the evaluation of the coverage of the species, the plots were divided into 100 subplots of 10 cm x 10 cm. The number of subplots filled by each species was computed. The usual phytosociological parameters were calculated and the other analyzes (diversity, evenness, similarity, dissimilarity, ANOSIM and NMDS) were performed. In total, 8157 individuals, distributed in 58 species, were sampled. Of these, 46 were native and 12 were invasive exotics. The native species with the highest importance value (IV = 50.65) was urtica dioica and the invasive exotic (IV = 18.91) was Dactyloctenium aegyptium. Invasive exotic species represented 9.12% of the density observed in the plots. In the analysis of similarity, dissimilarity and NMDS, differences in species composition were observed between the studied areas. The results indicated a high richness of native and exotic invasive weeds, which represent a great economic impact for the region's farmers, as well as for the natural ecosystems.
