The production of native species requires the knowledge of the best substrates and subsequent initial growth of these seedlings. This work aimed to evaluate the initial growth cedar seedlings (Cedrela fissilis Vell.) in different substrates and their initial establishment in field. The experiment was conducted in two stages. The first was conducted in nursery in a randomized block design with four replications. Each plot consisted of four seedlings in plastic bags. The treatments consisted of eight different substrates: T1 (sand+ soil+manure 1:1:1), T2 (sand+soil+Plantmax 1:1:1), T3 (soil+manure 1:1), T4 (soil+Plantmax® 1:1), T5 (soil+manure 2:1), T6 (soil+Plantmax 2:1), T7 (soil+sand 1:1) and T8 (soil). Plant height, stem diameter, number of leaves, canopy diameter and quality indexes were evaluate. It was found that the best growth and quality of cedar seedlings grown in nurseries were obtained with treatments sand+soil+manure (1:1:1), soil+manure (2:1) and soil+manure (1:1). The substrates used in the seedlings production in the nursery influence seedling growth cedar in the field, and the best results observed for height growth and stem diameter in nursery remain after planting in the field.Downloads
