Resumo: | Sugarcane cultivation using pre-sprouted seedlings has decreased the number of stalks used per hectare, increased the multiplication rate, improved seedling health, and increased planting uniformity. However, because this system has been only recently proposed, the number of studies evaluating this new technology is still scarce, particularly those examining the effect of the application of growth-promoting substances on seedling characteristics during the production phase. Here, we hypothesized that it is possible to combine the plant growth-promoting activity of humic acid (HA) with the inoculation of selected strains of plant growth-promoting bacteria (PGPB) to improve the yield of sugarcane seedlings compared with the individual application of these two techniques. The potential of the combined use of HA and PGPB as agricultural inputs was evaluated by conducting an experiment with sugarcane micro cuttings in a greenhouse. Treatments included control, PGPB, HA, and PGPB with HA. At the end of the experiment (60 d after planting), the plants were subjected to biometric evaluation. The results indicated that it was possible to combine HA with selected strains of PGPB (Burkholderia sp.) to improve the yield of seedlings compared with individual HA and PGPB treatments. HA, PGPB, and HA + PGPB increased the total dry matter compared with the control by 23%, 25%, and 36%, respectively. Therefore, the use of HA-based plant regulators in combination with PGPB was more effective than the isolated use of these inputs for the treatment of micro cuttings and improvement of sugarcane seedling yield. |

Contudo, por ter sido proposto há pouco tempo, o número de trabalhos com essa nova tecnologia ainda é escasso, especialmente quanto ao comportamento dessas mudas frente à inoculação com bactérias promotoras de crescimento de plantas. Hipótese desse trabalho propõe que é possível combinar o efeito de promoção do crescimento vegetal dos ácidos húmicos (AH) com a inoculação de estirpes selecionadas de bactérias promotoras de crescimento de plantas (BPCP) com vias a obtenção de respostas superiores à aplicação isolada de ambos na produção mudas de cana de açúcar. Para avaliar o potencial do uso combinado de AH e bactérias diazotróficas endofíticas como insumo agrícola, foi instalado um experimento com microtoletes de cana-de-açúcar em casa de vegetação. Os tratamentos incluiram o controle, BPCP, AH e BPCP com AH. Ao final do experimento (60 dias após o plantio) as plantas foram avaliadas biometricamente. Os resultados demonstraram ser possível combinar os efeito dos AH com a inoculação de estirpes selecionadas de BPCP (Burkholderia sp.) com maior desenvolvimento das mudas comparadas com o tratamento isolado com AH e BPCP. AH, BPCP, e AH + BPCP aumentaram a matéria seca total em 23%, 25%, e 36%, com relação ao controle respectivamente. Assim, o uso de biorreguladores a base de AH combinados com BPCP é positivo e complementar comparativamente aos insumos geralmente usados no tratamento de microtoletes para a produção de mudas de cana de açúcar.UEL2018-05-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionScientific CommunicationAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3133410.5433/1679-0359.2018v39n3p1365Semina: Ciências Agrárias; Vol. 39 No. 3 (2018); 1365-1370Semina: Ciências Agrárias; v. 39 n. 3 (2018); 1365-13701679-03591676-546Xreponame:Semina.
