Today, the world wide garden is devoted to Grape is one of the most important valuable garden products and it plays an important role in Iran internal and external marketing as well. Improving grape growth approaches can help stable production and suitable marketing of this product which needs applying Reforming and Improving Grape Orchard innovation. Hence the importance of Reforming and Improving Grape Orchard in this study, the course seeks innovative features to Reforming and Improving Grape Orchard and its impact on innovation adoption among grape growers are discussed. This study has been done using a hybrid methodology based on case study. Contextual and validity of the questionnaire was confirmed by special panels and using convergence tests through the main components analysis of the grouped data, the structure validity was determined. In addition, its stability was confirmed due to performing initial study and applying Cronbach alpha test. A sample containing 260 people of 3942 grape growers of Khoramdareh Township were selected by a multi-level sampling method and were interviewed. The results showed that Innovative features such as attitudes towards innovation advantage, complexity and lack of compatibility, test taking and viewing capabilities of these innovations among grape growers under the cover of garden development plans (2008 - 2011) and those under the cover of Toba plan (2008 - 2001) is higher than others respectively.

The general purpose of this research was to study effective factors on job stresses. This is an applied research in term of goal, and also descriptive research in terms of the degree to control of variables. Research tool was questionnaire. In this research the standard questionnaires of Osipow job stress and Health and Safety Executive (HSE) can be used. Present research statistical society included in all experts (engineers) and active members of agriculture and natural resources engineering organization system in Garmsar province that 149 person selected as sample using simple random sampler. In order to validity study, research tool ensured experts and for reliability measurement the elementary test performed through the completion of 30 questionnaires and alpha Cronbach calculated. Data statistical analysis performed using computer software SPSS17. According to the obtained findings of progressive regression analysis determined that among the studied variables, three variables of responsibility, physical environment and role workload assigned in total 46/9 percent of job stress variance changes.

The main purpose of this study was performance evaluation of coordinating agricultural extension offices of Guilan’s Agricultural Organization (Jihad-e-Keshavrzi) based on the proposed model of Saravanan et al. (2009). This research was an applied research in terms of goal. This research also was a descriptive research in terms of the degree to control of variables and was a field research in term of data gathering. Statistical population consisted of all managers and experts of coordinating agricultural extension offices, Agricultural Organization (Jihad-e-Keshavrzi) service centers and other extension organizational experts (N=311), and also paddy farmers in the areas of Agricultural Organization (Jihad-e-Keshavrzi) management and service centers, Guilan Province who were selected by the multi-stage cluster sampling method. To perform sample size calculation, the minimum sample size table of Bartlett et al. (2001) has been use. Accordingly, the group of experts (n=183) and of farmers, 278 as sample were selected. The research instrument was a questionnaire which its face and content validity was assessed by a panel of experts. Reliability of the farmers and experts’ questionnaires was calculated on the basis of Cronbach's alpha coefficient test (α=0.85 and 0.97 respectively), therefore it can be concluded that the questionnaire had acceptable reliability to conduct the study. Data analysis was performed using the software SPSSwin18 and TOPSIS technique. Ranking results based on TOPSIS technique showed that Amlash County was in the first rank and Rasht County was in the last rank in comparison to other counties. This finding implies that the agricultural extension offices of Rasht must pay attention to the importance of performance indicators such as the total expenditure intensity, expenditure intensity, clientele contact intensity and technical manpower: cultivator ratio and in this regard particularly to the development, monitoring and evaluation standards and measures to improve the performance

This study investigated the Attitudes and Behaviors of farmers to Apply Integrated Pest Management by using the Developed Theory of Planned Behavior (TPB).The present research is applied in terms of purpose, and in terms of research methodology is descriptive-correlation in terms of collecting field data. The population of this study consisted of 104 agricultural who participated in the integrated pest management cucumber training. The instrument used for data collection was a questionnaire. Alpha value was 68%. Data were analyzed using the software SPSSversion20.The results indicated that there was a significant relationship between History of farming, distance of the agricultural land to housing, income and number of sessions in training classes and tend to use integrated pest management. Also the results showed a significant negative relationship between family size and the behavior to use integrated pest management. There was a significant relationship between number of sessions in training classes and behavior to use integrated pest management. Also, Hierarchical Regression Analysis showed that attitude, subjective norms and moral norms predict 49/5 percent of variable tend to use integrated pest management. Furthermore, Hierarchical Regression analysis showed that past behavior can predict 43/6 percent of variable behavior to use integrated pest management

This study is an applied research using a descriptive and also considered as a quasi - experimental research. The population of this study was all 11,300 farmers in the province of Bushehr in 1391. Using the Cochran formula, the number of population sample determined 226. The purpose of Study was to identify factors affecting farmer's participation in the management of irrigation and drainage systems. As a result, the participation of beneficiaries in the management of irrigation and drainage networks was moderate. Based on the results of factor analysis, five factors are more effective in the beneficiaries’ participation, which explain 57.96 percent of its variations in the management of irrigation and drainage networks, these include irrigation network and financial factors, conditions related to the administration history of manufacturing and services government, land conditions, accesses to water irrigation and job characteristics of farmers

The purpose of this study was to assess the role of supervisor engineers in the management of rice production in the Shoushtar Township. This study is an applied research and conducted by survey. Research method was descriptive-correlative and causal inductive. The population covered by supervisor engineers was (N1 = 1249) and non-covered was (N2 = 258). The sample, respectively (n1 = 216) and (n2 = 135) were determined. To confirm the validity was used panel of experts. For reliability, Cronbach's alpha coefficient was used in all cases is greater than 7.0. According to the results of the mean of the production management in the field covered by supervisor engineers and non-covered there is a significant difference in the production management. The result suggests that the supervisor engineers the management of the production process in 3 stages of rice were good. Based on the obtained correlation between the number of contacts with supervisor engineers and supervisor engineers visit farmers with production management there was a significant positive correlation in (99%) level. Also with 99% confidence, the average production management according participating in training courses organized by the engineers, there is a significant difference
