The experiment was set up in Two-factor factorial experiment in Completely Randomized Design (CRD) with five replications.Two weeks after fertilizer treatment (WAP), data were collected fortnightly. Data collected were subjected to analysis of variance and treatment means found to differ significantly were separated using Duncan Multiple Range Test (DMRT) at p = 0.05. Results indicate significant differences in seedlings heights, collar diameter and in leaves count. All results obtained show that poultry droplet medium performed better. Since the use of cow dung improved the seedlings growth significantly, it is therefore recommended that it should be used to raise M. altissima seedlings in nurseries.
