| description | Currently, Brazil has a demand for 21 million hectares of forest restoration, and consequently, a great demand for good quality native species seedlings. It is important to employ techniques that reduce the costs of productive inputs as substrates and the irrigation water. In this context, the paper aimed to evaluate the growth of Poincianella pluviosa (DC.) L.P.Queiroz seedlings produced in four substrates elaborated with different solid wastes (sewage sludge, composted sawdust, and charcoal powder) and under two irrigation depths (0,03 L/h and 0,05 L/h). The experiment was conducted in completely randomized design with a 4 × 2 factorial arrangement (four substrates and two irrigation depths), eight treatments in total. The physical (porosity, density etc) and chemical (nutrients and organic matter contents) properties of substrates were evaluated. The seedlings shoot height, collar diameter, shoot, root, and total dry mass were measured. The substrates S1- pure sewage sludge and S2- sludge + sawdust (1:1) presented the better physical characteristics and substrates S1- pure sewage sludge and S3- sludge + charcoal powder (1:1) showed the better nutritional composition. For the growth in height there were no difference between the substrates and the irrigation depths. The substrates formulated with 50% of sludge and 50% of sawdust or charcoal powder, combined with the higher irrigation depth, resulted in seedlings with higher collar diameter, biomass, and quality, for which they are recommended to produce P. pluviosa. |

O Brasil tem hoje uma demanda por 21 milhões de hectares de restauração florestal, e como consequência, uma enorme demanda por mudas nativas. Desta forma, torna-se essencial o uso de técnicas que possam maximizar o uso dos substratos e da água de irrigação, visando a produção de mudas de alta qualidade. Diante deste cenário, o presente estudo teve como objetivo avaliar o crescimento de mudas de Poincianella pluviosa (DC.) L.P.Queiroz produzidas em quatro substratos elaborados a partir de diferentes resíduos (subsolo, lodo de esgoto, serragem compostada e moinha de carvão) e sob duas lâminas de irrigação (0,03 L/h e 0,05 L/h) por dia. O experimento foi conduzido em delineamento inteiramente casualizado com esquema fatorial 4 × 2 (quatro tipos de substratos e duas lâminas d’água), totalizando oito tratamentos. Os substratos foram avaliados quanto às suas características físicas e químicas. Foram mensuradas a altura, o diâmetro de colo e a massa seca da parte aérea e radicular das mudas após 105 dias de emergência. Os substratos S1- lodo de esgoto puro e S4- lodo de esgoto + serragem (1:1) apresentaram melhores características físicas e os substratos S1- lodo de esgoto puro e S3-lodo de esgoto + moinha de carvão (1:1) exibiram melhor composição nutricional. Para crescimento em altura não foram observadas diferenças entre os substratos e lâminas de irrigação testados. Os substratos constituídos por 50% de lodo e 50% de moinha de carvão ou serragem e com a maior lâmina de irrigação resultaram em mudas com maior diâmetro, biomassa e qualidade, sendo os mais indicados à produção de P. pluviosa.
