Resumo: | The aim of this work was to evaluate organic-mineral substrates in the production of Erythrina velutina seedlings. The experiment was conducted in a split-plot completely randomized design, subdivided in time, with 10 replications. Five substrates (S) were used: S1 = soil; S2 = soil + tanned bovine manure (20%); S3 = soil + simple superphosphate (300 g m-3); S4 = soil + simple superphosphate + micronutrients (300 g m-3, 50 g m-3); S5 = soil + simple superphosphate + micronutrients (300 g m-3, 50 g m-3) + tanned bovine manure. The substrate was composed of soil, and bovine manure tanned in the ratio 4:1, according to each treatment. Five seedlings were collected at intervals of 14, 28, 42, 56 and 70 days after sowing. The analyzed variables were: shoot length, number of leaves, collar diameter, leaf area, stem, leaves, shoots, roots and total dry mass, and shoot and roots dry mass ratio. The analyzed variables showed significant effect with the organic-mineral substrates. The substrate composed of soil with simple superphosphate (300 g m-3), micronutrients (50 g m-3) and 20% of tanned bovine manure is indicate to produce Erythrina velutina seedlings.
