Resumo: Este estudo teve como objetivo avaliar o crescimento de mudas de T. grandis Linnaeus filius. utilizando como substrato orgânico e fonte de nutriente o lodo do caleiro. O experimento foi realizado em casa de vegetação, com os tratamentos: 0,0; 30,0; 60,0; 90,0; 120,0 e 150,0 Mg ha -1 de lodo de caleiro. Aos 120 dias após a semeadura, foram avaliados: altura das plantas, diâmetro do caule, biomassa das partes aérea e radicular e os atributos químicos do solo. Observaram-se incrementos decrescentes para as características morfológicas avaliadas à medida que se adicionou o resíduo, e este, por consequência, alterou todas as características químicas do solo. O lodo de caleiro nas doses estudadas não foi adequado à produção de mudas de T. grandis. Palavras -chave: Tectona grandis;Resíduo de curtume; Salinidade; Desenvolvimento de mudas. Characteristics of the soil and the seedlings of teak plants submeted to liming sludge.Abstract: This study aimed to verify to evaluate the growth of T. grandis Linnaeus filius seedlings using as organic substrate and source of nutrient, the sludge lime. The experiment was conducted in a nursery using the treatments: 0.0 ; 30.0 ; 60.0 ; 90.0 ; 120.0 and 150.0 Mg ha -1 of sludge lime. At the end of the experiment, were analyzed plant height, diameter, shoot and root dry biomass, and chemical soil. It was observed reduced increments in all morphologic characteristics evaluated as the residue is added, and therefore, changed all the chemical characteristics of the soil. The sludge liming in the doses studied was not adequate for the production of T. grandis seedlings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
