The present study was carried out at the CIEFOR Puerto Almendra FCF - UNAP, San Juan Bautista, Maynas, Loreto. Objective, to determine the increase in height and diameter; survival and quality of 200 seeds of Ocotea aciphylla in a nursery with different substrates. The planting beds were prepared at ground level, with material from the area; The simple randomized experimental design with 8 treatments and 25 repetitions was used. The greatest increase in height was recorded by the CF treatment (black earth (20%) + chicken manure (50%) + rotten stick (30%) with pre-germination treatment) with 32.2 cm; while the greatest increase in diameter is reported by the BF treatment (black earth (50%) + chicken manure (30%) + rotten stick (20%) + pre-germination treatment) with 0.28 mm. Seedlings of Ocotea aciphylla “cinnamon moena” registered results between 70% and 96% of survival for the treat...
