The current study aimed to identify and analyze the factors influencing acceptance or rejection of irrigation system in apple orchards of Urmia city, as the center of apple production in West Azerbaijan Province, by applying survey research method and Rogers' Diffusion of Innovations Model. Based on the results, 57% of the respondents believed that implementation of drip irrigation using a common source of water (well) had many problems, 63% of them also considered the system unsuitable for old orchards. About 64% of the respondents believed that, in current situation, the relative profitability of the system was in the range of medium to low. 77% believed that drip irrigation systems did not have high performance due to various reasons. According to 81.5% of the respondent’s opinion, applicability of these systems is complex compared to traditional methods, because of design, performance, employment, and administrative bureaucracy, obtaining facilities, repair and maintenance. According to the Cox-Nell and Nagelkerke statistics, the variables included in the model are able to explain, respectively, 0.50 and 0.68 of the variance of the drip irrigation acceptance variable. According to the obtained results, the most important recommendations applicable in the region, are using successful models and reference groups to provide practical trainings on irrigation systems, increasing the relative benefit and reducing the risk of investing in drip irrigation, reviewing the process of designing, implementing, the workflow and the quality of equipment in drip irrigation systems, solving problems related to issuing the necessary permits for orchards that do not have ownership documents and, finally, avoiding the use of drip irrigation in old traditional orchards.

The purpose of this research was to analyze the mechanisms affecting conservation agriculture in order to optimize the management of agricultural water in irrigated wheat fields of Kermanshah province. A qualitative and quantitative research method was applied in order to identify the mechanisms affecting conservation agriculture. In the qualitative section, 45 influencing mechanisms were identified by using content analysis method. In the quantitative part, factor analysis was used and the identified mechanisms in the qualitative section were categorized. Target population of this research consisted of 2000 wheat farmers in Kermanshah province, among whom 322 people were selected by simple random sampling method. The data were collected and analyzed by using a questionnaire, whose face and constant validity was evaluated by the faculty members and experts; and its validity was obtained as 0.89. The results of the analysis of the mechanisms led to the identification of eight effective factors in conservation agriculture and water resources management. The factors were supportive factors, educational and extension factors, provision of infrastructure, national and local culture, policy and planning, institutional factors, research and development, and monitoring and evaluation, respectively. These factors were able to explain about 84% of the variance of the total mechanisms of conservation agriculture for optimal agricultural water management.

Shortage of water is one of the main factors limiting development of agricultural activities. This has led to the fact that farm management and productivity of agricultural water need full participation of farmers. Therefore, the purpose of this study was to analyze the factors affecting barriers and facilitators in adoption/development of new irrigation systems by farmers. The statistical population of this study included 70 experts of the departments of Agriculture Jihad whose viewpoints were collected and analyzed. Data was collected by using a questionnaire as research tool and SPSS and Lisrel software were used for analysis. To determine the reliability of the questionnaire, alpha coefficient was used by R software, which amounted to 91 percent, reflecting the reliability of data in similar conditions. In order to identify the factors affecting barriers and facilitators in development of new irrigation systems, factor analysis was used. The results of analysis in development barriers section led to identification of five barriers that included farmers awareness, technical problems, administrative costs, government policy, and technical knowledge. These barriers could explain about 69 percent of variations of adopting new irrigation systems. Identified facilitators included satisfaction of progressive farmers, clear comparative advantages, and monitoring and institutional partners. These facilitators could explain about 40 percent of variations about adoption of new irrigation systems. Also, in order to identify direct and indirect relationships between identified barriers and facilitators, Structural Equation Modeling (SEMs) was used. Results of this section showed that farmer awareness (β= 0.87), administrative costs (β= 0.67), clear benefits (β= 0.54) barriers had a direct impact on the development of new irrigation systems. Also, other results of this study showed that there was an indirect and weak relationship between administrative costs, farmers’ interests, and farmers’ awareness in development of new irrigation systems. According to the results, none of the identified facilitators had any significant effect on the adoption of new irrigation systems by farmers.
