The study was conducted to evaluate the effects of Moringa oleifera extracts, NPK fertilizer and Poultry manure on soil properties and growth performance of Solanium melongena in the Giri area of Federal Capital Territory, Abuja, Nigeria. Randomized Complete Block Design with 3 replicates was used. Data collected include pre- planting composite soil analysis, post harvest soil analyses, height per plant, number of fruits per plant, number of branches per plant and fruit yield. In the 2 years of the experiment, application of the Moringa extracts on the soil properties and growth performance of S. melongena was significant. Soil pH was improved from 5.4 to 6.7 with application of Moringa extracts. In both 2012 and 2013, highest fruit yields (9.5 t ha -1 in 2013 and 10.5 t ha -1 in 2013) were obtained from stands of garden egg that received Moringa leaf extract combined with NPK fertilizer applied at the rate of 100 kg ha-1. The yield of the crop was also improved by application of poultry manure though not significantly different from those given the solution obtained by soaking the bark and cut branches of Moringa stands. In all, the poorest results were obtained from the control plots.

Key words: Comparative, Moringa oleifera, extract, poultry manure, decoction, NPK fertilizer.
