Abstract: For over three decades (1981-2020), the Nigerian government has set out various policies to stimulate the country’s real economic growth. The government did this by inducing funds in different sectors: agriculture, e: agriculture power. Contrastingly, the desired outcome of real economic growth has not been achieved. Hence, this study examined the impact of real agricultural outputs, human capital and power supply on Nigerias real economic growth using quarterly time-series data from 1981-to 2020; and exploited the Cobb-Douglas Production for theoretical backings. After reviewing relevant works of literature, the analytical techniques (Johansen cointegration (long-run relationship) and Dynamic Ordinary Least Squares (DOLS) (long-run impacts) were found worthy and were employed.
