عنوان مقاله [English]
The importance of using water resources optimally due to the country's climate is not overlooked. For this reason, increasing water use efficiency is one of the main goals in achieving sustainable agriculture. One of the important and effective solutions is to use modern irrigation methods and replace them with traditional methods. In this regard, the discourse on the use of subsurface irrigation systems has grown in the country over the last few years. Perhaps due to reasons such as providing direct fertilizer application, the lowest water losses and higher irrigation efficiency, it has a special place. However, it is important to note that because of the short life operation of the subsurface irrigation system in crops, farmers should be aware of the advantages of the system to the technical and administrative constraints of the underwater irrigation system, and based on a Comprehensive knowledge, decision making. The purpose of this study was to investigate the capabilities and limitations of implementation of subsurface irrigation system in irrigation of crops. In this regard, the advantages and disadvantages of implementing the system have been investigated in the first alfalfa irrigation system of about 8 ha in Qazvin province.
