In this paper results of different irrigation systems, regarding to energy consumption and energy ratio, are presented. Energy consumption in irrigation and energy output through yield were analyzes for three different irrigation systems (self-propelled rain wing, self-propelled rain gun and linear system) in order to establish the optimal exploitation and energy parameters of the given irrigation systems. Results show that, concerning the depth of irrigation, good results can be obtained with the lower depths (0-30 cm). Concerning the irrigation application rate it was concluded that with the lower application rate and higher number of irrigation cycles better water usage can be obtained. Energy consumption of the mobile irrigation systems shows that the optimal relation of the energy output (yield energy) and energy input through the irrigation process in case of mobile rain wing is the lowest (12.29) and that with mobile linear device highest (288.19). Energy consumption in tillage ...and sowing in the system of conventional tillage was 2519.31 MJ/ha. Energy of irrigation varied depending on type of irrigation system. With the mobile linear system energy consumption was 814.35 MJ/ha, with mobile irrigation wing 1338.54 MJ/ha and with the self-propelled rain gun 8041.17 MJ/ha.
