The huge human and material resources that Nigerian Government have committed into implementation of agricultural extension system are yet to yield expected dividend. The book filled a gap in knowledge by evaluating the features of Training and Visit (T&V) management system that has been put in place, as a basis for rightly judging the effectiveness of the Unified Agricultural Extension Service (UAES), which adopted T&V in Abia and Akwa Ibom States of Nigeria. As an on-going evaluation, it provided empirical data needed for judging the utility of the UAES and T&V system and the feedback required for effective and efficient extension management. It is a veritable tool for use by policy makers and stakeholders, such as the World Bank, in the process of taking informed decision about agricultural extension strategy. The book contributed to knowledge and expanded supportive literature for further studies. The book is suitable as a classroom text for students in the Colleges of Agriculture and University Faculties of Agriculture in the Topics. It is especially invaluable for Agricultural Economics and Extension Students. It serves as a guide for Programme Monitoring and Evaluation.
