Effort has been made to identify the perceived constraints of the farm scientist and their magnitude as well as relation with job satisfaction of the two State Agricultural Universities (SAU’s) of West Bengal. It reveals that most severe constrains faced by the farm scientists is financial and budgetary constraints followed by infrastructural constraints, situational constraints, communication constraints, administrative and managerial constraints and constraints related to extension activities. It has been also found that paucity of fund for research; lack of coordination among different departments and lack of promotional opportunities are the most crucial constraints that stand in the way of getting the desired level of job satisfaction among the farm scientists.
