The aim of this study was to determine energy consumption and the relationship between energy input and output in greenhouse strawberry production using adaptive neuro-fuzzy inference system (ANFIS). Data used in this study were obtained from 30 randomly selected greenhouse strawberry producers using a face to face interview. The average energy consumption and yield were calculated as 922565.89 MJ ha-1 and 75062.50 kg ha-1, respectively. The results revealed that diesel fuel with 80% of total energy use were the main energy consuming inputs. Also, the energy forms results indicated non-renewable and direct energies was more than renewable and indirect energies, respectively. ANFIS model is developed based on a hybrid learning algorithm, with R2 for predicting output energy being 0.993. Results indicate that the multi-level ANFIS is a useful tool to managers for large-scale planning in forecasting energy output of agricultural production systems.
