Due to the growing population in cities, one of the most neglected issues is the urban agricultural development. This study seeks to investigate the impact of economic, social, cultural and managerial mechanisms on the development of urban agriculture in the Kraj city. This research is of applied type and after presenting the basics of the subject and research background, the data obtained from the distribution of the questionnaire in the statistical population of 127 experts have been analyzed using Smart-PLS software. Based on the results of this study, the KMO number (greater than 0.7) and the significance number of Bartlett test (<0.05sig) indicate the appropriate factor analysis for the data. The results of this study indicate the appropriateness of all questions in the process of factor analysis and because the number of subscriptions to the questions is more than 0.5, the validity of the questions has been confirmed. Also, after analyzing the results in this study, it was found that four assumptions of this study, including economic mechanisms, social mechanisms, cultural mechanisms and management mechanisms and related items have affected the development of urban agriculture in Karaj.

The purpose of this research was to study factors affecting conflict management from the perspective of Tehran Keshavarzi Bank employees. The methodological approach of this study was descriptive- correlative. The research population consisted of 1200 Keshavarzi Bank employees, which 291 of them selected using randomizing sampling method (n=291). Validity of the instrument was established by a panel of experts consisting of senior faculty members in Sari University and research committee advisors in Tehran Keshavarzi Bank. Reliability analysis was conducted by using and Cronbach alpha formula and result was 0.87. Dependent variable was conflict management and independent variables include factors of economic, social, management and extension- education.  The results showed that economic factor explained variation of 19% of control style in conflict management and factors of extension- education and economic explained variation of 5.6% of collaborating style in conflict management. Also factors of social and economic explained variation of 24.2% of avoiding style in conflict management, and factors of management, extension- education and social explained variation of 18.9% of accommodating style in conflict management. Also factors of management and extension- education explained variation of 23% of compromising style in conflict management.

Agricultural development is one of the most important priorities in the national development programs of developing countries. This cannot be achieved without applying and using new technologies in the agricultural sector through precision agriculture. Since the acceptance and application of this type of technology is facing challenges and obstacles; The aim of this quantitative study is to "investigate the factors influencing the adoption of UAV technology in two retrospective and prospective perspectives". The required information was collected in the form of questionnaires made by the researcher among the potato farmers of Kermanshah city. In order to analyze the data, the statistical method of logistic regression was used. The findings indicated that only three variables of perceived risks, the intention to use drones and the perceived need for technology were effective on the acceptance of drone technology, so that by reducing each of these variables, the possibility of increasing the adoption of drone technology among farmers. Potatoes work more. Therefore, holding promotional courses and granting financial facilities to potato farmers can be effective in facilitating the adoption of drone technology.

Frost as one of the environmental crises accompanying climate change phenomenon has caused significant annual economic losses in the agricultural sector production. This survey research was carried out with the aim of analyzing frost protection practices among apple orchardists of Kakan Dehestan, Boyer Ahmad county (N = 1241, n=112). The data collection tool was a researcher-made questionnaire. Face validity confirmed by a panel of experts. In order to measure reliability, a pilot study was conducted and Cronbach's alpha coefficient estimated (0.69< α <0.89). Based on the results, the most frequent behaviors among the gardeners were predictive behaviors and the use of technological measures was the least prevalent ones. Orchardists were clustered into two groups of compatible organizers and incompatible procrastinators. The results of the t-test analysis showed that the two groups had adopted different behaviors regarding the protection of gardens in dealing with frost; in such a way that the group of compatible organizers was significantly different from the group of incompatible procrastinators in terms of forecasting actions, planning actions, control actions, traditional actions, and techno-innovational actions. Results of the logistic regression showed that orchardists with more coping appraisal, threat appraisal and household size and less physical costs were more likely to adapt protection behaviors. According to the findings of the research it is necessary to develop frost protection measures through encouragement of gardeners via incentive policies, establishing gardeners' organizations and group formation to deal with frost protection.

This study was conducted with the aim of investigating the factors influencing the farmers' behavioral intention to accept Arta tobacco cultivation in the eastern regions of Gholston province. The research type was an applied research which was done by a surveying method. The statistical population was 662 tobacco farmers in Minoodasht and Dozin regions located in the east of the province, of those 154 samples were selected as a sample population by using Cocheran's formula. The data gathering tool was a questionnaire. The questionnaire validity was assessed by discriminant and convergent validity methods and the questionaire reliability was evaluated by composite reliability method using PLS software. The hypotheses test and structural modeling equations results showed that the variables attitude with a coefficient of 0.717, personality with a coefficient of 0.322, perceived ease of use with a coefficient of 0.267, trust with a coefficient of 0.167 and perceived risk with a coefficient of 0.138 were the strongest determination of farmers' behavioral intention in accepting Arta tobacco, respectively.
