摘要

The paper studies the effects of the liberalization of the Nigerian fertilizer sector, vis-à-vis the sustenance of the present dual fertilizer distribution arrangement, on maize production in Nigeria. Time series data was collected for the period 1990-2006. A multiple regression model was specified with aggregate fertilizer use, maize hectarage and a dummy variable designed to capture the effects of the changes induced by fertilizer liberalization measure, as explanatory variables. Aggregate maize output was the dependent variable. Results of this study indicate that a significant decrease in aggregate maize production followed the Federal Government’s liberalization of the fertilizer sector in 1997. The statistically significant decrease in Maize production is attributable to the statistically significant decrease in fertilizer use during the fertilizer liberalization period. The paper concluded that the sustenance of the present dual fertilizer distribution arrangement?has a negative effect on maize production in Nigeria.
