Resumo: Copper (Cu) is a metal that can become toxic to sorghum when present in high concentrations in the soil. The use of plant growth-promoting rhizobacteria can be an alternative for the development of sorghum [Sorghum bicolor (L.) Moench] in soil contaminated with copper. The objective of this study was to determine the effect of Azospirillum brasilense inoculation on the development and copper levels of sorghum cultivated in soil contaminated with Cu, enabling the reuse of these areas. The experimental design was randomized blocks in a factorial arrangement (9 × 2), with nine doses of copper [(0: natural content of the soil), 30, 60, 90, 120, 150, 180, 240, and 300 mg of copper kg-1 of soil] with and without A. brasilense inoculation, with six replicates. In the treatment without inoculation, a dose of 200 kg-1ha was applied. Plant height (PH), stem diameter, dry mass of the air part (DMAP), volume, length, and root dry mass (RDM), relative index of chlorophyll a and b, and copper contents in DMAP and RDM were evaluated. The inoculation with A. brasilense allows a higher index of chlorophyll a and b and the development of the aerial part of the sorghum, reducing copper content in the aerial part, enabling the reuse of soil containing 52.5% clay, contaminated with up to 300 mg of copper kg-1 of soil. Inoculation with A. brasilense increases the specific surface area (SSA) of sorghum roots compared with non-inoculated plants grown only with nitrogen fertilization in soil contaminated with copper.

A utilização de rizobactérias promotoras do crescimento de planta pode ser uma alternativa para o desenvolvimento do sorgo [Sorghum bicolor (L.) Moench] em solo contaminado com cobre. Objetivou-se determinar o efeito da inoculação de Azospirillum brasilense no desenvolvimento e teores de cobre do sorgo cultivado em solo contaminado com Cu, possibilitando o reaproveitamento dessas áreas. O delineamento experimental foi de blocos casualizados em arranjo fatorial (9 × 2), sendo avaliadas nove doses de cobre [(0: teor natural do solo), 30, 60, 90, 120, 150, 180, 240 e 300 mg de cobre kg-1 de solo] com e sem inoculação de Azospirillum brasilense, com seis repetições. No tratamento sem inoculação foi realizada aplicação de nitrogênio na dose de 200 kg-1 ha. Foram avaliados a altura de planta, o diâmetro do colo, a massa seca da parte aérea (MSPA), o volume, o comprimento e a massa seca radicular (MSR), o índice relativo de clorofila a e b e os teores de cobre na MSPA e MSR. A inoculação com Azospirillum brasilense possibilita maior índice de clorofila A e B e desenvolvimento da parte aérea do sorgo, reduzindo o teor de cobre na parte aérea, possibilitando o reaproveitamento de solo contendo 52,5% de argila, contaminado com até 300 mg de cobre kg-1 de solo. A inoculação com Azospirillum brasilense aumenta a área superficial específica de raízes de sorgo em comparação a plantas não inoculadas cultivadas somente com adubação nitrogenada em solo contaminado com cobre.Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)2024-03-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/166010.5327/Z2176-94781660Revista Brasileira de Ciências Ambientais (RBCIAMB); v. 59 (2024): RBCIAMB - ISSN 2176-9478; e1660Revista Brasileira de Ciências Ambientais (RBCIAMB); Vol. 59 (2024): RBCIAMB - ISSN 2176-9478; e16602176-94781808-4524reponame:Revista Brasileira de Ciências Ambientais (Online)instname:Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)instacron:ABESenghttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/1660/949Copyright (c) 2024 Revista Brasileira de Ciências Ambientais (RBCIAMB)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Juliano Cesar daSilva, Rodrigo Ferreira daSantos, Victorino Menegat dosGiovenardi, Andréa da RochaSilva, Danni Maisa daCanepelle, EduardoSilva, Ana Paula da2024-04-11T00:42:07Zoai:ojs.www.rbciamb.com.br:article/1660Revistahttp://www.rbciamb.com.br/index.php/Publicacoes_RBCIAMBhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/oairbciamb@abes-dn.org.br||2176-94781804-4524opendoar:2024-04-11T00:42:07Revista Brasileira de Ciências Ambientais (Online) - Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)false
