Summary: Malt bagasse is an important waste from breweries, with high potential of usage in various animal and human food areas. Nonetheless, there are few studies of its in natura usage as soil conditioner for various vegetables seedings production. Thus, this works objective was evaluate the interaction among different substrate compositions, using brewery waste as component, and different shading levels at Georgian cabbage germination. For that, the experiment was made in five different shading levels (50%, 70%, 90%, 70% with plastic and full sun) and three different substrates moistures with distinct compositions: S1 (33,33% of manure; 33,33% of sandy soil; 33,33% of clayish soil), S2 (83% of earthworm humus; 15% of fine glyceride charcoal; 2% of mammon dumpling), S3 (33,33% of brew waste; 33,33% of sandy soil; 33,33% of clayish soil), in an completely randomized design, with five repetitions for each shading level and substrate concentration. Germination beginning occurred in the third day after sowing (DAS) and lasted until the tenth DAS. The S2 substrate stood out, followed by S1, with similar results in height, roots length, germination percentage, and germination speed index. On the other hand, the substrate composed of malt bagasse obtained the worst results in all shading conditions, being not indicated to kale seedings production.
