%X This paper mainly investigated the interactive effects between liming and mineral fertilization in the acid soils in maize crop of the south-west of the DRC, two factors including liming as main factor, at two levels (with and without) and three levels of mineral fertilizers (controls without fertilizer, NPK 12-24-12, NPK12-24-12   Urea 46%) as secondary factor, were used in a split-plot design with three replications. The results showed that the soils neither limed nor fertilized considerably reduced (p < 0.05) the agronomic performance of maize. However the interactions between liming and mineral fertilizers have significantly influenced (p < 0.05) and positively the growth parameters (height of the insertion) and flowering (day at 50% male flowering and female flowering), and therefore a significant difference (p < 0.05) for grain yield, harvest rate and appearance of the ears. Liming combined to mineral fertilization, in the proportions required for maize cultivation, improved around 50% of the production per unit area of maize gain in the acidic soils of Mvuazi.
