Abstract
Como parte de las investigaciones que se llevan a cabo en el Centro de Mecanización Agropecuaria (CEMA) la evaluación de un conjunto de máquinas para la labranza conservacionista., se realizó un estudio cuyo objetivo es determinar el costo energético del rodillo de cuchillas CEMA 1400 para cobertura vegetal. Se determinaron los costos energéticos horarios (MJ/h) y por unidad de área trabajada (MJ/ha), contemplando la energía secuestrada en materiales de construcción, fabricación, transporte; combustibles; lubricantes; reparación/mantenimientos y mano de obra. Los resultados mostraron que los mayores costos horarios del conjunto, están representados por la energía secuestrada en combustible con un 60,07% del total, siendo los costos energéticos por unidad de área trabajada de 628,19 MJ/ha.
