dc.description.abstractSeedlings of Albizia lebbekoides, Eucalyptus robusta, Eucalyptus torilliana, Gmelina arborea, Pterocarpus indicus, and Swientenia macrophylla were fertilized, outplanted and maintained on 3 sites of varying altitudes (470 masl, 780 masl, 1330masl) on-farm in upland villages for 21 months. Side-dressing and controlled release served as fertilizer treatments.Statistically significant differences in the measured traits, plant height and diameter, were noted between fertilized and non-fertilized plots of E. robusta, G. arborea and S.macrophylla. No significant differences were observed of fertilized and non-fertilized plots of A. lebbekoides, E. torilliana and P indicus on one hand, and between the fertilization methods on the other. Altitude, a major topographic factor, influenced plant response to fertilizer by its effect on soil temperature and the chemical and physical proprieties of soil. Temperature and quantities of Calcium, Magnesium, Phosphorus and Potassium decreased with increased altitude, while organic carbon and organic matter increased. Other factors which affected plant response to fertilization were the age of growth and
