The present study aimed to analyze the Farmers' Behavior in Using Low-pressure Irrigation System. This qualitative study is performed in East Azarbaijan province. The statistical sample population consists of 393 farmers out of 112010 farmers of East Azarbaijan province. The research instrument was a researcher-made questionnaire that face validity and convergent validity were used to assess the validity of the questionnaire. The results of confirmatory factor analysis showed that the mean of variance extracted was acceptable for the studied structures (AVE≥0.522). Also, the combined reliability value was suitable for all structures (CR≥0.785). The SPSS version 20 and AMOS version 21 were used to analyze the data. In order to better understand the main factors influencing the behavior of low-pressure irrigation systems, the research model was based on the Decomposed Theory of Planned Behavior (DTPB) and extended. In this study, two variables of moral norm and self-identity have been added to the initial model of the decomposed theory of planned behavior, which has made it more complete and comprehensive. The results of using structural equation modeling showed that EDTPB had a suitable effectiveness and efficiency to predict farmers' behavior in using low-pressure irrigation system. In addition, variables including compatibility, advantages, facilitators, self-efficacy, attitudes, moral norms, self-identity and behavioral control were explained 72% of the variance changes. Also, the variables of benefits and adaptation explained 33% of the variance of attitudes towards the use of low pressure irrigation system and the variables of self-efficacy and facilitators explained about 21% of the variance of farmers' behavioral controling of the application of low pressure irrigation system.

The current study aimed to determine and analyze Solutions of low-pressure irrigation system in the East Azarbaijan Province. Data collection was performed using semi structured interview method. We conduct an interview with experts of irrigation, soil and agricultural extension sectors as well as famers who had a purposeful use of technics. In order to achieving appropriate research validity, we applied triangulation -data sources and monitored them by the experts.Statistical analysis was performed using MAXQDA software version 10 based on basic theory including open, oriented and optional coding stage. The result indicates that based on there were 6 main categories, 25 sub-categories as well as 171 conceptual units. Effective measures should be taken into consideration in order to develop the low-pressure irrigation system. The results showed that measurements including creating educational-promotional mechanisms, reducing administrative complexity, improving farmers' participation, long-lasting monitoring, follow-up and consulting during and after implementation, financial supports and creating infrastructure activities.

Water consumption in agriculture, increasing irrigation efficiency, and reducing water consumption against the constant yield of the crop are very important. Therefore, the study of water consumption efficiency in different irrigation methods has a significant role in the macro-agricultural and industrial planning of the country. In the present study, the efficiency of gravity irrigation systems (channelet), low pressure, and pressure irrigation in the lands north of Karkheh Khuzestan (arayez 2&3 project) has been investigated. The results showed that the irrigation efficiency in the pressurized irrigation method was the highest so the total efficiency in the pressurized irrigation system is 64.2% higher than channelet irrigation and 55.8% higher than low-pressure irrigation. Also, irrigation efficiency in low-pressure irrigation methods is about 5.3% higher than in channelet irrigation. Economical studies and analysis of different irrigation systems showed that although the initial cost of setting up a pressurized irrigation system is higher than gravity and low-pressure irrigation, in a long time, it will be economically viable while the return on investment in this project is maximum 5 years.
