An important share of total agricultural productivity growth has been attributed to increased use of fertilisers. This study uses household survey data of 2305 collected by International Institute of Tropical Agriculture (IITA) in Nigeria to investigate the impact of mineral fertiliser use on maize productivity and welfare of the smallholder farmers in rural Nigeria.   We used PSM combined with endogenous treatment effect model to control for both observable and unobservable household heterogeneity. About \mbox{68\,\%} of the farmers use fertiliser.  The percentage of farmers that use fertiliser (\mbox{92\,\%}) was higher among the proportion of those that were aware of the fertiliser.  The farmers that uses fertiliser have higher yield, income, per capita expenditure than those that did not use fertiliser. Main occupation, gender of household head, access to credit, total household asset, farming experience, land ownership, training,  irrigation and farm size were the variables that positively and significantly influence the farmers' decision to use fertiliser The Average Treatment Effect on the Treated (ATT) was estimated to be between 167.68--\unitfrac[170.63]{kg}{ha}. Fertiliser use generate between 15 \%-\mbox{19\,\%} increase in maize productivity and \mbox{14\,\%} increase in welfare. The results also show heterogeneity in the impact of fertiliser adoption across gender, access to credit and training and irrigation. Our findings show that adoption of mineral fertilisers significantly increase maize productivity and improved rural farming households' welfare. The policy implication is that the use of fertiliser should be promoted through creation of awareness of its potential benefits and ensuring availability and affordability of fertiliser.}
