The species Dipteryxodorata (Aubl.) Willd. – Fabaceae) is distributed in the Amazon and produces noble wood used for different means; moreover, its seeds are used in the perfume and cosmetics industry, and as medication in folk medicine. Luminosity and substrate affect growth and quality before planting when seedlings are produced in plant nursery. Thus, wood particles of Ochromapyramidale (Cav. ex Lamb.) Urban in substrate supplemented with macro- and micronutrients at 0%, 30%, 50% and 70% shading were used to replace chicken manure in the production with high-quality D. odorata seedlings. The experiment was installed in the plant nursery of Tropical Forestry Experimental Station of INPA, in Manaus – AM. It was based on substrates composed of clay soil, sand and chicken manure at ratio 3:1:1/2of O. pyramidale particles to replace manure at ratios 3:1:1/2; 3:1:1 and 3:1:2. The completely randomized design was adopted, to enable factorial (4x4) analysis through ANOVA; means were compared through Tukey test at 5% at 306 days. Height, neck diameter, number of leaves, leaf area and, root, stem, leaf and total dry matter were measured; the survival was evaluated and, quality standard, assessed through the height/neck diameter ratio and Dickson Quality Index.The substrate with half part of O. pyramidale particles at 70% shading led to higher growth of D. odorata seedlings, to higher quality standards and better survival than chicken manure, allowing environmental valorization through the use of wood and residues of O. pyramidale from plantations in the Amazon.
