  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.

  Considering the limited access to fresh water resources and intense plant respiration and high evapotranspiration in deserts and arid regions, subsurface irrigation seems to be the most appropriate method for cultivation. The aim of this study was finding a proper subsurface irrigation to supply moisture for plant roots using bio-composite water pipes to supply water for panicum. Experimental design was factorial experiment conducted based on completely randomized block design with three replications in the Faculty of Agriculture in Tarbiat Modarres University in 2015. Main factors included subsurface irrigation using three types of bio-composite water pipes manufactured P3, P8, P9, subsurface irrigation using subsurface porous clay capsules and flood irrigation (control treatment). Secondary factors included three drought stress levels of 25, 50, and 100% of soil field capacity (FC). Results showed that, subsurface irrigation treatment using water pipe P8 and drought stress level of 25%, and FC decrease for 12.68%, was the lowest water consumption in irrigation. In addition, in subsurface irrigation, height, wet and dry weights were significantly different at %1 level compared to flood irrigation. Therefore, with regard to responsiveness of panicum water demand to subsurface irrigation using bio-composite water pipes, and considering the results of this research using subsurface irrigation by bio-composite water pipes, it is recommended to optimize water consumption for urban areas located in arid and semi-arid regions.

  Clogging of emitters is one of the main problems in subsurface drip irrigation. The objective of this study was investigation of effect of Geocomposite on wetting pattern in subsurface irrigation system. This research was conducted in lysimeters located at Shahrekord University research field. The study was conducted as a factorial experiment based on a completely randomized design with 10 treatments and three replications of three factors. The first factor of experiment was geocomposite shape with the same area on two levels (shape square with dimensions (4 × 4) square centimeters and rectangular with dimensions (2 × 8) square centimeters), the second factor was combination of geocomposite material on two levels (two layers of geotextile on both sides of Geonet and The second level, a layer of geomembrane and a layer of geotextile on both sides of geonet), the third factor of placement in the soil at on two position (horizontal and vertical) and emitter with envelopment (in two position horizontal and vertical) were used as control. The ground wet and wet the maximum of soil depth profiles were measured. The results was showed that geocomposite of shape square with dimensions (4 × 4) square centimeters for a layer of geomembrane and a layer of geotextile on both sides and how to align horizontally in the soil wet ground level by lowering the 21.55 percent and increased 17.1 percent wet the soil deep profile compared to control (emitter with envelopment horizontally in the soil) is the most effective and best conditions on wetting profiles.  Manuscript profile

  According to the statistics, surface irrigation system covers more than 95% of the country's lands and current efficiency of the system is estimated as less than 35%. Hence, the need for detailed understanding of surface irrigation efficiencies in the irrigated lands and presenting appropriate solutions to increase such factors are too important to measure and should be taken in line with optimal consumption of agricultural water which covers more than 70% of the country's available water. Hence, a farm was selected in Malajnood village area which was irrigated in furrow method and then was evaluated during the two phases of irrigation. The underlying tests were conducted using partial Parshall with input water flow of 3.66, 1.97L?S. Elliot7Wlker's two-point method was used to determine infiltration equation coefficients. The relationship between needed water and exact moisture distribution which was equal to 2 samples of irrigation indicated two cases of incomplete irrigation. Findings of the study indicated that deep percolation ratio was 23.33 and 45.63 and the irrigation adequacy was 100% that showed the high water losses and low water efficiency, but the full supply of plant water needed.
