Productivity and operational cost of mechanized weed control in young stands of Acacia mangium in the northern of Costa Rica
Two mechanical weed control operations were assesed in young Acacia mangium stands located in the northern part of Costa Rica. Through a series of time and movement observations the productivity, efficiency and costs of both operations were determined. The two operations presented efficiency values...

Through a series of time and movement observations the productivity, efficiency and costs of both operations were determined. The two operations presented efficiency values higher than 55%. The productivity of the agricultural tractor was higher (4,98ha/day) than the obtained with trimmers (1,15 ha/day). Total cost per hectare was $13 for the agricultural tractor and $52 for trimmer. Se evaluaron dos tipos de chapea mecanizada en plantaciones jóvenes de Acacia mangium, localizadas en la zona norte de Costa Rica. Mediante un estudio de tiempos y movimientos se determinó la productividad y costos de ambas operaciones. Se encontraron valores de eficiencia superiores al 55 % siendo la operación de chapea con tractor agrícola la que reportó mayor porcentaje con un 73%. La operación de chapea con tractor agrícola presentó una productividad mayor (4,98 ha/jornal) que la operación de chapea con motoguadaña (1,15 ha/jornal) Los costos por hora y por jornal fueron menores para la chapea con motoguadaña, sin embargo, el costo total por hectárea fue más elevado ($52 respecto a la operación con tractor agrícola debido a una menor productividad de la mano de obra. 2012-09-10 2021-06-08T22:00:52Z 2021-06-08T22:00:52Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.tec.ac.cr/index.php/kuru/article/view/376 http://hdl.handle.net/2238/12564 spa https://revistas.tec.ac.cr/index.php/kuru/article/view/376/309 application/pdf Editorial Tecnológica de Costa Rica Revista Forestal Mesoamericana Kurú; Vol. 8 Núm. 20 (2011): Enero- Junio 2011; pág. 27-30 2215-2504 |
