- Productivity and energy efficiency of three tillage systems for maize (Zea mayz L.) production Jaime Ruiz-Vega Niurka Mena-Mesa Fidel Diego-Nava Miguel Herrera-Suárez Ingeniería Rain sustainability fed agriculture animal traction mechanized traction The amount of inputs and dry matter yields of grain, stover and weeds werequantifi ed in six sites located in the districts of Zaachila and Etla, in the Central Valleysof Oaxaca Region, México. The tillage systems evaluated, which are the most widely usedfor corn production in this region, were full animal traction (FAT), mixed traction (MXT) andmechanical traction (MT). The higher productivity was achieved in the MT system, followedby the MxT system. According to the energy balance, the largest energy effi ciency (EE) wasachieved in the FAT system with a value of 34.4 and the least one with the MT system. Thelowest EE of the MT system was associated to a higher use of machinery operations andthe use of petrol derivate products. No signifi cant differences in EE were found betweenthe FAT and MxT systems; when the weed’s dry matter production was considered, EE inthis last system was increased 14%, while in the FAT system an 8% increase was observed.Therefore, besides the FAT system, MxT is also recommended because it is common to haveplots smaller than 1 ha in the region and mechanical plowing is more effi cient for primarytillage operations, while animal power can be used as a renewable source of energy for taskssuch as weeding and transport. 2015 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43042289008 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.76
