Canizales, Sergio Andrés; Celemín, Jhon Sander & Mora-Delgado, Jairo

Abstract

This study was aimed to identify and recognize the main uses of weeds in pastures of livestock farm located in the high watershed of Magdalena River, Department of Tolima (Colombia), where 8 farms were analyzed. The farms were located in six municipalities of Tolima: Ibagué, Piedras, Armero, Guamo, Alvarado and Suárez, under a dry tropical forest zone (bs-T) and pre-wet forest (bh-PM). The fieldwork was conducted during 5 months on rainy season and 4 months on dry season of 2007. We evaluated 2 transects with 10 sampling sites distributed over 100 m of each transect, using a one meter square for sampling. The samples collected were identified at the TOLI Herbarium. We found 113 species belonging to 30 families and 82 genera, were the predominant families Fabaceae check for this species in other resources with 24 species (20,5%) and Asteraceae check for this species in other resources with 20 species (17,1%). The most abundant species throughout the area were Senna obtusifolia check for this species in other resources and Achyranthes indica check for this species in other resources . Found 22 species (18,8%) are of interest beekeeping; 20 species (17,1%) have some medical use, 12 species (10,3%) are conservative and 11 species of soil (9,4%) are used especially in food summer where forage is scarce.

 es Diversidad y uso de arvenses en pasturas de fincas ganaderas del Alto Magdalena (Tolima, Colombia)
Canizales, Sergio Andrés; Celemín, Jhon Sander & Mora-Delgado, Jairo

Resumen

El objetivo del estudio fue identificar y reconocer los principales usos de las arvenses en pasturas de fincas ganaderas de la cuenca alta del rio Magdalena en el Departamento del Tolima donde se analizaron 8 fincas de los municipios de Ibagué, Piedras, Armero, Guamo, Alvarado y Suárez, ubicadas en zona de vida bosque seco tropical (bs-T) y bosque húmedo premontano (bh-PM). El trabajo de campo fue realizado durante 5 meses de la época lluviosa y 4 meses de la época seca del año 2007. Se evaluaron 2 transectos, con 10 sitios de muestreo distribuidos en cada transecto de 100 m, empleando un marco de 1 m2 para el muestreo. posteriormente, las muestras recolectadas fueron identificadas en el Herbario TOLI, se identificaron 113 especies, pertenecientes a 30 familias y 82 géneros; las familias predominantes fueron Fabaceae check for this species in other resources con 24 especies (20,5%) y Asteraceae check for this species in other resources con 20 especies (17,1%). Las especies más abundantes de toda el área de estudio resultaron Senna obtusifolia check for this species in other resources , y Achyranthes indica check for this species in other resources . 22 de las especies encontradas (18,8%), son de interes apícola; 20 especies (17,1%), tienen algún uso medicinal; 12 especies (10,3%), son conservadoras de suelo y 11 especies (9,4%), son de uso alimenticio en especial en la época de verano en donde escasea el forraje.
