IntroductionThe transfer of sustainability training means applying the skills, attitudes, and knowledge acquired from training to the workplace to help sustainability and environmental protection. This study aimed to conduct a behavioral analysis of sustainability training transfer among farmers that had attended extension-training courses on the Land and Conservation Agriculture Project (LCAP) in Iran.MethodsThis research is quantitative and applied research that was carried out via a standardized survey. The research population was composed of all farmers who attended LCAP extension training courses in the three provinces of Golestan, Fars, and Khouzestanin, Iran (N=1204). 291 farmers were selected through stratified random sampling. A panel of experts established the content and face validity of the questionnaire. A pilot study was conducted to check the reliability by calculating Cronbach's alpha.Results and discussionFindings indicated that most farmers had sustainability training transfer at a high level. The analysis with a structural equation model revealed that perceived content validity, transfer design, opportunity to use, supervisor support, trainer characteristics, peer support, motivation to transfer, transfer effort -performance expectations, performance coaching, and personal capacity for transfer influenced farmers' intention to transfer sustainability training significantly and positively. Furthermore, farmers' intentions had a significant effect on their transfer of sustainability training. It can be concluded that a sustainability training transfer system is applicable to a training context related to sustainable agriculture and can provide a useful instrument for agricultural education organizations when investing in farmers' training.
