In this regard, the present study has conducted a spatial analysis of water and energy consumption in Qazvin irrigation network. For this purpose, first, the dominant cropping pattern of the study area was extracted and then the water requirement was estimated for the products in the cropping pattern using CropWat 8.0 software. To estimate energy consumption, energy consumption in the sprinkler and drip irrigation systems, groundwater pumping, diesel fuel, labor, seeds, machinery (tractors and combines), chemical fertilizers, and pesticides for each available secondary field in the irrigation network was calculated. The results showed that the highest energy consumption in all secondary farms indirect energy consumption is related to diesel fuel with 40% of total energy consumption and in indirect energy consumption belongs to nitrogen fertilizer with 20% of total energy consumption. Also, in the energy used to pump water in irrigation systems at different heads required for pumping for crops in the dominant cropping pattern, alfalfa consumed the most energy with a value of 4811.44 Kwh / ha and corn consumed the least energy with a value of 1194.19 Kwh / ha. According to the results, the impact of diesel fuel, chemical fertilizers, and water pumping on energy consumption are high, thus controlling the consumption of these inputs would significantly reduce energy consumption.
