Abstract

In recent years, due to the limitation of water resources, the use of pressured irrigation methods has received much attention. Although the use of pressurized irrigation systems increases the water productivity, these systems have received less attention in terms of energy use and environmental aspects. So, the aim of this study was to evaluate the energy and environmental indicators of almond orchards under surface and pressured irrigation methods in Shahr-e Kord and Saman region of Chaharmahal and Bakhtiari province. The required data, including information about inputs and energy consumed in almond orchards, were collected using questionnaires and face-to-face interviews. No significant difference was observed regarding the performance of almond production in the two mentioned irrigation systems. Examining the results of water consumption in two systems showed that the pressured irrigation system consumes about 82% less water than the surface irrigation system, while the energy consumption in this system was about 12% more than the surface irrigation system. Energy ratio of almond production in surface irrigation systems was computed as 2.40, while the corresponding value in pressured system was 2.07. In other words, surface irrigation had better conditions in terms of energy indicators. The investigation of the environmental indicators of two irrigation systems showed that the use of the pressured irrigation system reduces the environmental damage
