Levantamento fitossociológico de plantas daninhas nas áreas de potencial produtivo na Escola Agrícola de Jundiaí/RN

Abstract

This study aimed to conduct a phytosociological survey of weed species present in the productive potential areas of the Jundiaí Agricultural School (EAJ/UFRN), located in the municipality of Macaíba, Rio Grande do Norte, Brazil. The research was carried out in four distinct agricultural areas using the random plot method with 0.25 m² sampling units. Four plots were sampled in each area, totaling 16 plots, in which the species were collected, identified, and analyzed based on phytosociological parameters such as frequency, density, abundance, and importance value index. These parameters were also used to evaluate floristic diversity. The results showed the presence of species with high adaptability to the agricultural environment, with some dominating the studied areas. This survey contributes to the understanding of the local weed flora and provides support for more effective integrated management strategies, promoting sustainable practices in the productive areas of EAJ. The most frequently observed species in the study were Euphorbia heterophylla, Cyperus rotundus L., and Axonopus affinis.
