An experiment was carried out at Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró - RN, for screening the effect of substrate for germination of seeds and seedling growth of Moringa oleifera Lam. It was utilized a completely randomized design with four treatments (substrates: T1= 75% sand + 25% bovine manure, T2= 100% washed sand, T3= 75% sand + 25% worm castings and T4= 75% sand + 25% sawdust) and four replications of 25 seeds. The seeds were sown in the substrates contained in wooden boxes (7,5 cm long x 23,5 cm wide x 39 cm deep). Each box was filled with approximately 6 kg of substrate. The substrates were irrigated once a day (until the tenth day), then twice a day until the end experiment (19 th day). Seedling height, root length, number of leaves, whole seedling fresh and dry matter weights, germination velocity index and germination percent were evaluated. It was concluded that the mix 75% sand + 25% worm castings was the most suitable for the initial growth of moringa and the substrate containing 100% sand provided the best germination index for this species.
