“…Thus, rhizobacteria LEBM 105, 109, 112, 152 and 154 can be defined as plant growth promoters. Harthmann et al (2010) also verified in onions microbiolized with rhizobacteria differences in percentage, compared to the control, ranged from 15.7 to 24.4% for productivity of bulbs.…”

Plant-growth promoting rhizobacteria are an alternative to increase the productivity, adding value to the productive system of crops like okra. We aimed to evaluate the agronomic characteristics of okra genotypes after seed microbiolization with nine strains of rhizobacteria. The experimental design was in randomized blocks, in a 2x10 factorial scheme, using two okra genotypes, cultivar Santa Cruz 47 and hybrid Dardo, nine strains of rhizobacteria, LEBM 103, 105, 109, 112, 118, 134, 135, 152 RESUMODesempenho agronômico de cultivares de quiabeiro sob efeito da microbiolização das sementes com rizobactérias As rizobácterias promotoras de crescimento de plantas surgem como alternativa para incrementar a produtividade, agregando valor ao sistema produtivo de culturas como o quiabeiro. Este trabalho objetivou avaliar o rendimento agronômico de duas cultivares de quiabeiro após a microbiolização das sementes com nove cepas de rizobactérias. O delineamento experimental utilizado foi em blocos inteiramente casualizados, em esquema fatorial 2x10, sendo dois genótipos de quiabo, cultivar Santa Cruz 47 e híbrido Dardo, nove cepas de rizobactéria, LEBM 103, 105, 109, 112, 118, 134, 135, 152 e 154, além de uma testemunha (sem microbiolização), com quatro repetições. As variáveis analisadas foram: número de frutos por planta (NFP); diâmetro médio dos frutos (DM); produtividade (PDT); massa fresca dos frutos por planta (MFFP) e massa média por fruto (MMF). Verificou-se que a utilização das rizobactérias LEBM 109, 112, 152 e 154 condicionou maiores valores de MFFP (1202,7; 1086,5; 1158,2 e 1175,9 g, respectivamente), PDT (24,1; 21,7; 23,2 e 23,5 t/ha, respectivamente) e NFP (78,0; 69,4; 73,27 e 76,5, respectivamente), em relação às demais cepas e à não utilização da microbiolização das sementes do hibrido Dardo. Para a cultivar Santa Cruz 47 as rizobactérias LEBM 105, 112 e 152 proporcionaram maiores valores de MFFP (896,7; 769,0 e 762,2 g, respectivamente). Avaliando-se os genótipos ao utilizar cada rizobactéria, para as variáveis MFFP e PDT, verificou-se que apenas para a rizobactéria LEBM 105, não houve diferenças entre os genótipos. Conclui-se, que a microbiolização de sementes de quiabo com rizobactérias pode proporcionar ganhos de produtividade e com potencial de se tornar uma técnica viável. As rizobactérias mais recomendadas para o cultivo do híbrido Dardo são a LEBM 109, 112, 152 e 154, enquanto para o cultivo da cv. Santa Cruz 47 são as cepas LEBM 105, 112 e 152.

Growth promoting rhizobacteria may increase the yield of some crops. Several microbial products that stimulate plant growth have been marketed. Therefore, the objective of this study was to evaluate the effect of bacteria from Bacillus genera on the production of commercial carrot roots (Daucus carota L.) in field conditions. The following isolates: SF 264 (Bacillus spp.), SF 268 (Bacillus spp.) and commercial formulations based on SF 202 (Rizos®, B. subtilis), SF 266 (Quartz®, B. methylotrophicus) and SF 267 (Onix®, B. methylotrophicus) were evaluated in four experiments conducted in commercial fields of carrot production in the municipality of Rio Paranaíba, Minas Gerais-Brazil. Each plot was 6 m long and 1.75 m wide (10.5 m 2) including four double rows. An additional treatment containing only water was the control treatment. The experiment was designed as randomized blocks with five replications. The products Rizos ® , Quartz ® and Onix ® containing Bacillus spp. increased the production of commercial carrots roots of all cultivars and sites. The SF 268 and SF 264 isolates were efficient only in two and three experiments, respectively.

“…Hence, bacteria of the genus Bacillus are known to promote plant growth, as the effect reported by Harthmann et al (2010) when identifying the action of B. megaterium on the growth and yield improvement in onions. Besides, B. subtilis-based products are used for the biological control of plant diseases (Halfeld-Vieira et al, 2016).…”
