شناسایی عوامل مؤثر بر تمایل کشاورزان شهرستان باغملک نسبت به پذیرش سیستم‌های آبیاری تحت فشار: کاربرد مدل پذیرش فناوری دیویس

Abstract
The main purpose of this research was to explain the factors affecting the intention to accept pressure irrigation systems among farmers in the central part of Baghmalek county using the technology acceptance Mode (TAM). The statistical population included all the farmers in the central part of Baghmolek county, Khuzestan province (N= 3005), based on the Karjesi and Morgan table, a sample size of 343 farmers was selected using the stratified sampling method with proportional assignment. The data collection tool was a questionnaire whose validity was based on the opinion of the faculty members of Khuzestan University of Agricultural Sciences and Natural Resources and its reliability was determined through Cronbach's alpha. On the other hand, the Average Variance Extracted Index (AVE) was used to determine construct validity and the Composite Reliability Index (CR) was used to determine model reliability. The results of structural equations showed that the variables of attitude, usefulness and perceived ease predicted 68% of the changes in the variable of Intention of farmers to accept pressure irrigation, also, based on the results obtained from the final model of technology acceptance, the perceived ease variable with 28% direct effect and 44% indirect effect with the mediating role of attitude has the greatest effect on farmers' willingness to accept pressure irrigation systems. In this regard, it is recommended that the agricultural Jahad service centers hold orientation courses, classes, workshops and educational seminars to increase the perception of ease and usefulness as well as to improve the attitude of farmers regarding the benefits of pressurized irrigation systems, so that the willingness of farmers to accept Irrigation systems under pressure will increase.

1. Introduction
Today, the water crisis is increasingly worrying public opinion and it engages the scientific.The water shortage in most countries has caused farmers to use modern methods instead of traditional irrigation methods, have greater control over water consumption. Among the programs implemented in order to reduce water consumption and increase its productivity in the agricultural sector, is the use of pressurized irrigation method. The main purpose of this research was to explain the factors affecting the intention to accept pressure irrigation systems among farmers in the central part of Baghmalek county using the technology acceptance Mode (TAM). The technology acceptance model is adapted from Fishbein and Ajzen theory of reasoned action. The main components of Davis's technology acceptance model include perceived ease, perceived usefulness, attitude toward use, and behavioral intention.
2. Methodology
This study is applied research in terms of its purpose, non-experimental in terms of the amount and degree of control of variables, and descriptive-survey in terms of data collection.The statistical population included all the farmers in the central part of Baghmolek county, Khuzestan province (N= 3005), based on the Karjesi and Morgan table, a sample size of 343 farmers was selected using the stratified sampling method with proportional assignment.The data collection tool was a questionnaire whose face validity was confirmed by the faculty members of the Department of Agricultural Extension and Education. In addition, to determine the degree of reliability, pre-test and Cronbach's alpha coefficient were used.
3. Results
According to the findings, the attitude (45.8%) of the respondents regarding the use of pressurized irrigation is relatively favorable. In fact, farmers have a positive attitude towards the use of pressurized irrigation. The intention (53.3%) of farmers to use irrigation under pressure is relatively unfavorable and the intention (51.6%) of respondents to use irrigation systems under pressure is relatively unfavorable. The results of structural equations showed that the variables of attitude, usefulness and perceived ease predicted 68% of the changes in the variable of intention of farmers to accept pressure irrigation, also, based on the results obtained from the final model of technology acceptance, the perceived ease variable with 28% direct effect and 44% indirect effect with the mediating role of attitude has the greatest effect on farmers' intention to accept pressure irrigation systems.
4. Discussion
According to the findings of the research, perceived ease, both directly and indirectly, is a good predictor for the variable of farmers' intention to use pressure irrigation; That is, the more positive the farmer's understanding of the perceived ease of using pressure irrigation, the more likely he is to decide to use it. Based on the results of the research, a positive and significant relationship was found between perceived usefulness and ease directly and indirectly with farmers' attitude regarding the use of pressurized irrigation systems. According to the findings of this research, in order to increase the acceptance of pressure irrigation, it is necessary to focus on the attitude of farmers towards the use and their understanding of the ease and usefulness of the systems.
5. Conclusion
It is recommended that the agricultural Jahad service centers hold orientation courses, classes, workshops and educational seminars to increase the perception of ease and usefulness as well as to improve the attitude of farmers regarding the benefits of pressurized irrigation systems, so that the willingness of farmers to accept Irrigation systems under pressure will increase.
