One of the most used ways to perform agricultural management is to quantify the field efficiency. The rural producer may assess whether the equipment is being underutilized through this determination. This work aims to evaluate the Operational Capacity and Field Efficiency of corn silage production cultivated in a central pivot: a case study in an area of 2.3 ha. All the operations were performed using a Massey Ferguson tractor model MF 291, 4x2 TDA, nominal power of 73.6 kW (100 hp) at 2200 rpm. In order to evaluate the Operational Capacity, the total working time of each operation was measured separately from the preparation of the soil to the harvest in the whole area. The Efficiency was determined by the ratio of the Effective Operational Capacity for the Theoretical. The implements that required time for preparation and supply of inputs, preparation of spray solution and cart exchange were the ones that showed less efficiency. Even with greater width than the other implements, the sprayer presented the least efficiency due to the longer time of equipment movement and supply. The total maneuver time achieved by the equipment due to the circular land area may have contributed to the operations’ low efficiency.
