Abstract: A 4x4 factorial experiment in a Randomized Complete Block Design (RCBD) with three replicates was used to study the effects of hydrated lime on the growth of maize crop at National Special Programme for Food Security (NSPFS) field FCT, Abuja. The results showed that all fertility related properties of the soil were low with moderate to slightly acidity and the exchange site saturated with H+. 0.25 ton ha-1 of hydrated lime+0.25 ton ha-1 of NPK 15-15-15+2 ton ha-1 of Farm Yard Manure (FYM) incorporated into top soil increased the growth of maize more significantly than either 0.5 ton ha-1 of hydrated lime or zero lime. Therefore, on the average 0.55 ton ha-1 of lime was recommended for the site.
