The aim of this work was to evaluate the effect of different substrates in the germination and the initial growing of garden egg seeds (S. gilo Raddi), cv. Verde Claro. The experimental design was in completely randomized design, with fifteen treatments and four replications of one hundred seeds per plot. The treatments consisted of the use of substrates: residues of limestone mining with additional NPK (S1), residues of limestone mining with NPK and additional mud (1:1 v/v) (S2), residues of limestone mining with NPK and additional manure (1:1 v/v) (S3), residues of limestone mining with NPK and composed organic additional (1:1 v/v) (S4), red-yellow argisoil with liming and additional NPK (S5), red-yellow argisoil with liming, NPK and additional mud (1:1 v/v) (S6), red-yellow argisoil with liming, NPK and composed organic additional (1:1 v/v) (S7), red-yellow argisoil with calagem, NPK and additional manure (1:1 v/v) (S8), argisoil (pasture) (S9), meadow soil (S10); washed sand (S11), cambissolo eutrophic halico (S12), commercial substrate (PlantmaxR) (S13), residues of limestone mining (S14) and argisoil red-yellow eutrófíco (S15). After 18 days the following parameters were evaluated: germination percentage; emergence speed; mass of the fresh matter of the aerial part and of the radicule and mass of the matter drought of the aerial part and of the radicule. The best substrate used in the seeds germination were red-yellow argisoil with liming, NPK and additional manure, meadow soil and cambissolo eutrophic halico. However, the commercial substrate PlantmaxR was the best substrate in the production of the mass of the matter drought of the plantlets.
