Three pilot plans were selected and evaluated in each province. Field survey was employed and the required data collected via personal interview whit the farmers, filling questionnaires, and consulting with local experts and authorities in the studied regions. The reliability of data was assessed through Cronbach's Alpha coefficient being about 0.81. Results showed that in spite of many activities and attempts done in the studied regions (including educational and extensional affairs, administrate executive plans, i.e., irrigation and drainage networks, encouraging farmers to level their land channel lining, developing pressurized irrigation systems, etc.), the actual condition of water and soil management in the study regions is a long way away from the ideal. In general, the farmers' technical knowledge regarding soil and water issues was relatively low among the farmers questioned. However, they benefited from an average knowledge of agronomy e.g. rotation, application of nutrients and pesticides/herbicides mainly due to the fact that those inputs are payed for, and also one can actually observe their beneficial effects in the field. Most farmers (96.6%) did not measure the applied water to their fields, instead, they concentrated on their indigenous knowledge. Time (56%) and amount (64%) of irrigation water applied to the fields was based upon the farmer's local knowledge. Over 90% of the farmers involved in the study were not familiar with internet, computer and neither whit soil and water management softwares. The conducted training courses for farmers were mainly related to agronomy issues (81%). Rarely, they were provided training courses concerning such soil and water issues as, irrigation scheduling, irrigation management, and advanced irrigation methods. Main challenges in the regions under study were insufficient inputs (39%), water scarcity (28%), and inadequate agricultural machinery (12%). Educational priorities in the studied regions were also determined and presented.This study is aimed at an identification of farmers' knowledge level on soil and water issues, hardware and software requirements, and to characterize farmers' educational priorities in Tehran, Khuzestan, Golestan, and Mazandaran Provinces.

The main purpose of this descriptive – correlational research was to investigate the influence of membership in production cooperatives on the level of social capital. The statistical population for the study consisted of: poultry producers in cooperatives and private sector (N=216). One Hundred and sixty nine samples were selected through Stratified Random Sampling method. The sample size was determined using Bartlett et al (2001) table of sample sizes. Based on the results, the level of social capital within cooperatives was significantly higher than that within the private producers. The variables of: trust to strangers, intrapersonal trust, and information exchange within the social system, social cooperation and informal relations' network were the most conspicuous differentiators between cooperatives and private producers, meaning that members of production cooperatives, in terms of possession of these components stood at a higher level. The results finally indicated that the cooperatives help strengthen and promote social capital. In total, the social capital of production cooperatives amounted to a higher figure than that of the producers in the private sector.Cooperatives, established through a unification of human and economic capital within their members can lead to strengthening of the social capital.

The instrument of the study was a questionnaire, validated by a panel of experts. A pilot study was conducted to achieve the questionnaire's reliability. Results showed that a majority of the respondents had used Cell phones in agricultural education, to a limited extent. They had little familiarity with Mobile phone capabilities in different fields including agricultural education. Low proficiency, high communication costs and a lack of organizational financial support to undertake a part of the communication costs for agricultural education hindered its expected extensive use in agricultural education. Among cell phone applications, most respondents said theyused it either as a clock for waking up of making contacts with colleagues. On the other hand, they used it to a limited extent as an instrument to acquire local market information, GPS, getting and connected to internet. Factor analysis categorized the barriers in six categories of: information- communicational, psychological, credit- financial, proficiency, complexity, and improper context which together explained 68.26 percent of the variance.The goal followed in this study was to investigate the barriers that hinder the application of Mobile phone technology being communication in agricultural education, from the view points of agricultural extension educators of Ardabil Province.
