Abstract The main purpose of this study was to explore extension- training factors affecting the agricultural water management in Hamadan's potato production. This research has been done through a surveying method and data were gathered through a questionnaire tool. The study's population included 2341 potato farmers around Hamedan, which of those 330 samples were selected based on Cochran formula by a simple randomized sampling method. The content validity of the questionnaire was confirmed by a team of agricultural experts and professors in agricultural extension and education department of Bu-Ali Sina University. The reliability of the research instrument was determined using Ordinal theta coefficient (θ= 0/80-0/95). The results of the factor analysis showed that the factors affecting on agricultural water management can be classified in 6 groups. These were: the mass media factor, quality of extension services centers, experts' skills, local institutions and social networks, visit system, and training courses. These factors explained 70 percent of the total variance changes. Results from ordinal regression analysis indicated that knowledge, extension-training factors, and attitudes explained 25 percent of the probability of variance of agricultural water management variable.
