The problem with which this study is concerned is the description of changes in Nigeria that result from agricultural developments during the precolonial period to the present time. Emphasis is placed on the relationship between agriculture and other institutions, and the effect of agricultural change upon social phenomena such as population growth, family, industrialization, urbanization, and education. The Nigerian agricultural institution may be divided into three periods: the precolonial, the colonial, and the Republican agricultural eras. The data were obtained from published research reports, United Nations reports, government documents, newsletters, and economic journals. Primarily descriptive in nature, the thesis consists of six chapters. Emphasis was placed upon the historical development of Nigerian agriculture and the reciprocal impact between it and other Nigerian institutions.
