Resumo: | Jatropha curcas growth, like any other crop, depends on adequate management. However, there is little information about weed interference on the growth and control of this crop. This study aimed to identify the floristic composition of weeds in a J. curcas cultivation area in Maringá (Paraná, Brazil). The study was carried out in an area of 600 m2, where spacing between plants was 3 x 2 m. For the identification and quantification of weeds, we applied the method of inventory square.  Calculated parameters were: frequency, relative frequency, density, relative density, abundance, relative abundance and relative importance index. We identified 27 species of weeds, inserted in 12 families, that is, 10 dicotyledons and 02  monocotyledons. Among the dicotyledons, Asteraceae presented the highest number of weed species, with nine species. Bidens pilosa L. showed the highest relative importance index (Rii), 58,33  in the first sampling and 44,53 in the second one, followed by Thidax procumbens L., with Rii 8,13 in the first sampling and 7,09 in the second one.
