Agricultural extension is a form of rural development that relies on non-formal education. It is an old curriculum that works hand in hand with applied and academic agricultural scientific research. There is a wide debate about the necessity of separating the skills of the researcher from those of the agricultural extension worker. This study demonstrates what a scientific specialist needs to be a crucible that combines academic foundation, research mastery, and agricultural advisor skills. In this popular article, a quick presentation of the contents of 11 academic lectures separated into 10 sections on agricultural extension targeting master's students in plant protection at the University of Debrecen, Hungary. In the summary, a skilled agricultural supervisor needs broad academic capabilities, integrated research, scientific applications skills, and social characteristics, as well as the use of various media to understand the needs of the local community and build extension plans to affect the adoption of qualitative technologies that contribute to rural agricultural development. The article recommends the necessity to raise awareness on the importance of combining the characteristics of an academic, researcher, and agricultural advisor in agricultural societies.
