Water is a universal resource that sustains life and maintains seedling productivity. Biomass harvested and utilization for energy can affect water quality and quantity. Water quantity is the timing and total yield of water from a watershed, and it’s measured by total yield and peak flow over a specified period of time. This study assessed effect of frequency of watering (every day, 3 days and 5 days)  and quantity of moisture supplied (50 ml, 100 ml and 150 ml) on the growth performance of Entandrophagma angolense seedlings. The experiment was laid out in a 3 × 3 factorial in Completely Randomized Design (CRD) replicated 10 times. Factor A was 3 watering regimes (once daily, 3 days and 5 days interval) and factor B was 3 water quantities (50 ml, 100 ml, and 150 ml).The variables measured were; seedlings height, collar diameter, leaf production, biomass estimation, Relative Growth Rate (RGR) and Relative Turgidity (RT). Data collected were subjected to Analysis of Variance (ANOVA). Watering every day gave the best performance in terms of height, collar diameter, and leaf production with 9.71 cm, 3.25 mm and 5 leaves respectively. There was no significant effect (p > 0.05) of watering regimes on the seedlings height of E. angolense.
