This one-year project, conducted in potato-growing areas of Chaharmahal and Bakhtiari province, assessed the efficiency and productivity of direct, indirect, renewable, and non-renewable energy use in potato production under various irrigation systems and area sizes. A questionnaire was completed in several stages while field measurements were taken, and the data were converted into energy consumption per unit area using equivalence equations. Using the energy consumed and produced of inputs (irrigation water, electricity, machinery, human power, seeds consumed, chemical and animal fertilizers, pesticides, crop yield) for the production of potato crops under furrow, sprinkler, and tape irrigation systems, evaluation indices were calculated and analyzed. The average energy consumption and production per unit area were 154,537 and 160,424 megajoules per hectare, respectively, for the furrow irrigation systems (95,103 and 119,118), sprinkler irrigation (160,971 and 164,464), and tape irrigation (83,228 and 117,000). The average energy consumption efficiency was calculated to be 1.087, estimated at 1.18, 1.001, and 1.4 for the furrow irrigation, sprinkler irrigation, and tape irrigation systems, respectively. And in the mentioned irrigation systems, only 2.29, 2.63, and 2.62 kilograms of potato crop were produced for each megajoule of non-renewable energy consumed.
