The objective of this study was to evaluate the energy efficiency and environmental ramifications of alfalfa and silage barley production in Qazvin province, Iran, under different irrigation systems. The outcomes showed that subsurface irrigation utilized a total input energy of 95667.71 MJ ha-1, whereas surface irrigation had a positive impact on alfalfa production with a total input energy of 902683.07 MJ ha-1. Flood irrigation had the highest input energy of 110973.39 MJ ha-1 and the lowest output energy of 523644.31 MJ ha-1 compared to other irrigation methods for barley. The primary contributors to On-Farm emissions were diesel fuel and chemical fertilizers, but subsurface irrigation systems had lower levels of diesel fuel related pollutants due to reduced usage, while flooding irrigation systems had higher levels of such contaminants. Based on the finding, silage barley cultivation was a better option than alfalfa cultivation in terms of energy consumption and environment.
