Resumo: The industrial and urban waste can be used as a source of nutrients to contribute not only to reduce the cost of seedling production but also to reduce or solve environmental problems. This study aimed to evaluate the use of sewage sludge as substrate on the production of seedlings of Tectona grandis. Seedlings were grown in tubes with a volumetric capacity of 280 cm³, on substrates formulated with biosolids (BIO) associated with rice hulls (CAC) or shredded coconut fiber (FC) in proportions 80:20, 60:40, 40 60, 20:80 (v:v), and also with 100% of BIO, a total of nine treatment submitted to the comparison of control treatment (commercial substrate). The formed substrates were subjected to chemical and physical analysis. Ninety days after the sub culturing, the following biometrics characteristics were analyzed: shoot height, stem diameter, dry weight of shoot and root and Dickson quality index. The results indicated that the seedlings grown on substrates formulated with BIO and CAC showed the highest average height and shoot dry mass, while those produced with BIO and FC showed the highest average collar diameter. For the production of seedlings of Tectona grandis it is advised to use a substrate with proportions of 60 or 80% of biosolids when associated with coconut fiber, and 80% of biosolids when associated with rice hulls.

O presente trabalho teve por objetivo avaliar a utilização de biossólido como substrato na produção de mudas de Tectona grandis. As mudas foram produzidas em tubetes com capacidade volumétrica de 280 cm³, em substratos formulados com biossólido (BIO) associado à casca de arroz carbonizada (CAC) ou à fibra de coco triturada (FC) nas proporções 80:20, 60:40, 40:60, 20:80 (v:v), e também com 100% de BIO, totalizando nove tratamentos submetidos à comparação do tratamento testemunha (substrato comercial). Os substratos formados foram submetidos às análises químicas e físicas. Noventa dias após a repicagem, foram analisadas as seguintes características biométricas: altura da parte aérea, diâmetro do coleto, massa seca da parte aérea e radicular e o índice de qualidade de Dickson. Os resultados indicaram que as mudas produzidas nos substratos formulados com BIO e CAC apresentaram as maiores médias de altura e massa seca da parte aérea, enquanto que as produzidas com BIO e FC obtiveram as maiores médias de diâmetro do coleto. Para a produção de mudas de Tectona grandis, é aconselhável a utilização de um substrato com proporções de 60 ou 80% de biossólido quando associado à fibra de coco triturada; e de 80% de biossólido quando associado à casca de arroz carbonizada.Universidade Federal de Lavras (UFLA)2016-04-062017-08-01T20:15:20Z2017-08-01T20:15:20Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfTRAZZI, P.
