The aim of this research is to analyze the scientific effects of sabbatical leaves from agricultural faculty members\'s view. Methodologically, this research was carried out based on survey strategy. The sample of this research consisted of 166 faculty members of public agricultural universities and colleges of Ministry of Scientific, Research and Technology that were selected by randomized stratified sampling method. A questionnaire was used to collect data and its face and content validity was established using comments of a some researchers and reliability of the questionnaire was confirmed according to calculate Cronbach\'s alpha. Some items in Likert Scale measured research constructs. Based on calculated coefficient of variations each item of research constructs were prioritized. In order to determine direct and indirect effects of independent variables on finally usefulness of sabbatical leaves (as independent variable) the path analysis techniques by calculate multiple regression was employed. The results of path analysis showed that \"international professional interaction\" has most impact with path coefficient 0.835. \"Perceived process of sabbatical leaves\" (0.821), \"perceived personal benefits\" with direct effect (0.735), \"scientific professional performance\" with indirect effect (0.451) and finally \"perceived negative impact\" (-0.231) are ranked in other positions. Finally, according to research findings some recommendations are provided to promote effectiveness and usefulness of sabbatical leaves.
