• Morphological characteristics
• Organic waste
• Rabo-de-pitu
• Seedling quality

The objective of this study was to evaluate the potential of sewage sludge and organic waste as component of substrate for Chamaecrista desvauxii seedlings production. It was established ten treatments using four types of substrate: sewage sludge, carbonized rice hull, coffee straw and commercial substrate in different proportions. When the seedlings were at three months of age, the following parameters were measured: stem diameter, plant height, ratio between plant height and stem diameter, shoot dry mass, dry mass of root system, total dry mass, dry mass ratio of shoot/root dry mass and Dickson quality index (IQD). The substrates made with sewage sludge, carbonized rice hull and coffee straw provided better results of growth of seedlings. Moreover, the treatment with 60% sewage sludge + 20% carbonized rice hull + 20% coffee straw provided the best development of the morphological characteristics evaluated, and it was recommended for the production of Chamaecrista desvauxii.
