Abstract :

Energy efficiency is an important goal of sustainable agriculture. In the present study energy consumption in Cucumber cultivation in Borujen Township was investigated. Data related to amounts of inputs consumption and yield were collected from some local cucumber farms by using a face to face questionnaire based on random sampling method. The results showed that the amount of consumption energy in the production of cucumber is 290.7GJ.ha-1, energy production 48GJ.ha-1, output–input energy ratio 0.17, and energy productivity 0.21. Renewable and non-renewable energies were 90 and 10 percent of total input energy. Among the calculated total input energy, irrigation energy with 83.56% share of the total consumed energy has the highest energy consumption in the production of cucumber. Machinery and seed, respectively, with 0.001% and 0.22% share of total energy consumption, have the lowest consumption
