Research output published in reputable journals remains one of the the main criteria for ranking institutions across the world. Research findings contribute meaningfully to improved products, services, human life, and productivity. Anyanwu and Iloeje (1996) observe a gradual decline in research output from the Nigerian higher education sector from the late 1980s to the present. This paper is an empirical study using journals randomly selected from African Journals Online (AJOL). The data were analysed using Cochran's Test and T-test for comparative pair treatments. Findings reveal that there is no significant decline in research output and effectiveness from Nigerian universities, but Nigerian polytechnics were found to have a lower research output.
