The University of Agriculture, Abeokuta, (UNAAB) was established on January 1, 1988 by the Federal Government when four Universities of Technology, earlier merged in 1984, were demerged. This led to the creation of the first two Universities of Agriculture in Abeokuta and Makurdi.
On the same date, Professor Nurudeen Olorun-Nimbe Adedipe was appointed the pioneer Vice-Chancellor of the University. Professor Adedipe officially assumed duty on January 28, 1988. For many years the date which Professor Adedipe assumed duty was wrongly adopted as the foundation day of the University. Following a revisit to the instrument setting up the University, a Council decision at its 53rd Statutory meeting in June 2010 reverted the foundation date to January 1st 1988 as prescribed by the law which established the University.
