Resumen
- Introduction- The knowledge of the weeds present in the agroecosystems and their populations allows to project in a more accurate way the management programs of these. Objective-. Characterize the diversity of weed species and its coverage in 120 small farms of small farmers in the municipalities of Boyacá. Methodology-. The investigation was carried out in 15 farms in the municipalities of the Department: Chitaraque, Gachantivá, La Capilla, Nuevo Colón, Maripí, Santa Maria, Zetraquira and Tuta, in each of 0.5 ha plots where the landmarks were determined. of 1m2 the weeds present and the percentage of coverage. Results-. It was observed the presence of 255 species of weeds located in 167 genera and in 60 botanical families, being the most representative families Asteraceae and Poaceae, followed by Cyperacea, Fabaceae and Polygonaceae. The municipalities characterized by a higher relative temperature Chitaraque, Santa María and La Capilla present higher specific richness. The species with the highest frequency, present in all the municipalities was P aquilinum, in 75% of the municipalities were D. ciliata, and S. rhombifolia and in 62.5% Anthoxanthum odoratum, Bidens pilosa, Desmodium incanum, Hypochaeris radicata and Verbena litoralis. Conclusions-. From the monocotyledons, several species of Poaceas stood out with greater coverage, among them; C. clandestinum, three from the Brachiaria genus, three from Cynodon, within the Cyperaceae the species Dichromena ciliata, and one fern from the Dennstaedtiaceae family, P. aquilinum, which generally constitute important weeds of economic crops.
