Sufficient energy is needed in the right form and at the right time for adequate crop production. One way to optimize energy consumption in agriculture is to determine the efficiency of methods and techniques used. With the current increase in world population, energy consumption needs effective planning. That is why, the input elements need to be identified in order to prescribe the most efficient methods for controlling them. This study was undertaken in order to determine the direct and indirect energy consumption of field operations in a lowland rice production system of Nigeria. All the field parameters were taken in a wet puddling area of 0.25 hectares (25 m x 100 m) laid side by side in a randomized complete block design with three replications. Energy analysis carried out revealed that operational energy consumption for tillage is 41.9 %, planting 31.1 % and Harvesting 21.7 % for the production process and average grain yield was 4,800 kg ha-1.
