Recent global interest on biofuels, the potential of Jatropha curcas L. for production of biodiesel, and adaptation of this specie to survive as a commercial crop on marginal sites that have not been well understood gave rise to an experiment that evaluated the effects of inorganic fertilizer application on the growth and dry matter yield of J. curcas . The pot experiment was carried out at the crop pavilion of the Department of Agronomy, University of Ilorin, Nigeria (80 291N, 40 401E) and was designed as a completely randomized design (CRD) with five replicates. Number of leaves per plant (LNO) and plant height (PHT) were taken at two weekly intervals from 3 to 16 weeks after fertilizer application (WAF). Dry matter (DM) yields were taken at 8, 14, and 16 WAF. Data collected were subjected to the analyses of variance (ANOVA), and significant means were separated using the least significant difference at 5 percent probability level (LSD0.05). Results show that application of fertilizer at any rate produced significantly higher LNO, PHT, and DM values than the control. Though there were no appreciable variations among the fertilizer rates, the highest values of the parameters were obtained with the application of 120 KgN/ha. Further studies are recommended to validate the fertilizer optimum fertilizer requirements of the plant species. Keywords: Jatropha curcas L., biofuel, inorganic fertilizer application, plant gro
