ABSTRACT: The objective of this study was to determine the abundance, dominance, and coverage of weed species present in a developing sweet orange (Citrus sinensis L.) orchard in the state of Yucatán, Mexico. Weed collection was carried out in a sweet orange crop six months after transplanting, using the Valencia Late variety. For taxonomic identification, images of the adult plant with flowers, fruits, and seeds were taken, supported by an herbarium. The Importance Value Index (IVI) showed 8 predominate species, 48.73% with broad-leaves and 51.27% with narrow-leaves. The most predominant species were: Cyperus rotundus (Cyperaceae) and Sorghum halepense (Poaceae), with the higher IVI, at 100% and 40.3%, respectively. The presence of weeds represents a significant increase in the production costs in the sweet orange orchard, so its identification is essential for an effective weed management program.
