Abstract
The main purpose of this research is to identify and prioritize the technical, social and economical problems of localized irrigation systems in the cities of Qom province. Each of these problems has several variables and these variables are also made up of different characteristics. recognizing the existing challenges and evaluating and monitoring of problems, will be improve water productivity in the country. The research question was investigated in the form of a questionnaire among farmers. The common feature of all these farmers was the implementation and use of drip irrigation. The questionnaire was distributed to the farmers who had implemented the localized irrigation system. This measurement tool was used after the validity and reliability and sample size estimation in the data collection, and finally the data was analyzed using hierarchical component models by partial least squares (PLS) method. Cronbach's alpha coefficient was used to measure reliability. The t test was used to check the significance of the relationship between variables. The results showed that the technical with an alpha value of 0.81 has good reliability. The results of the evaluation showed that the technical aspect with an alpha value of 0.81 has adequate reliability in the answer and the farmers are unanimous in expressing their opinion. The economical and social aspects also have acceptable reliability with an alpha value between 0.5-0.75. In general, the results of the research showed that the main problems of the implemented systems in Qom province are caused by technical, economical and social aspects, respectively.
