The philosophy of the Postgraduate School is consistent with that of MOUAU, namely: to contribute to self-sufficiency in food and fibre production in Nigeria through teaching, research and extension. The University admitted its pioneer undergraduate students in 1993.   In response to popular demand, the University Senate in its meeting on February 10, 1995, established a Postgraduate Committee to oversee the development of postgraduate studies in the University. After due consideration, it was recommended that at least, a modest postgraduate programme should be started in October 1995.  The Postgraduate School was however, established at MOUAU in January 1997 with the appointment of its first substantive Dean, Prof. I.O. Akobundu. The present Dean is Prof. Okoro, Innocent Ajar.   The first batch of students registered for their courses in May 1997.

The MOUAU PG School offers opportunities for postgraduate studies in Agriculture, Applied and Basic Sciences, Management Sciences, and Education.  The PG School, through its Board and with the approval of the University Senate establishes policies for the conduct of postgraduate study and supervision of postgraduate students.

At the moment, the postgraduate school administers programmes of study leading to degrees of Master of Science (M.Sc.), Doctor of Philosophy (Ph.D.) and the Postgraduate Diploma programmes.

Colleges offering courses in various areas of specialization include: CAERSE, CASAP, CCSS, CAFST, CEET,  CNREM, CASE, COLMAS, COLPAS and COLNAS.

The PG School enjoys the services of highly qualified academic staff including Professors, Associate Professors, Senior Lecturers and Lecturers.  Some Departments use the services of guest lecturers/supervisors who are also renowned scholars from other universities within Nigeria. Twenty-five (25) students registered in May 1997 while thirty-nine students registered in the first semester of 1997/98 session.  The bottom-to-up approach will be adopted in the planning and implementation of research efforts – this implies that farmers own perception of their actual needs will guide research and extension activities of the University.  The University will adopt a learning-by-doing approach in imparting practical farming, Forestry, Fisheries, Engineering and scientific skills to the students.  To achieve this, the University will establish viable teaching and research farms as well as demonstration and conservation plots, nurseries and plantation, parks and gardens etc.  Suitable and functional infrastructure and equipment as well as adequate materials, will also be provided for laboratory research and training.  In pursuing the above objectives, the University will strive to maintain effective linkages with sister Universities of Agriculture in Nigeria, Agricultural Research Institutes, University Faculties of Agriculture, ADPs, public and private sector Agricultural Enterprises, etc.  Collaboration will also be sought with relevant oversea Agricultural Institutions, including the International Agricultural Research Centres (IARCs).
