“…Inoculation with Bacillus subtilis can favor soybean development, especially in the biological control of plants, production of natural antibiotics and protective effect against secondary soil phytopathogens (Araújo & Marchesi, 2009;Kuhn & Pascholati, 2010;Pavan et al, 2011;Gagné-Bourque et al, 2015;Jardin, 2015), in addition to the growth and development of the root system, and consequently greater absorption of water and nutrients (Hungria et al, 2013;Ji et al, 2014;Galindo et al, 2018). Thus, it would be possible to obtain an increase in soybean seed yield, as verified in the present study, without the statistical increment in grain mass.…”

“…Considering the limitations of biological N fixation (BNF) in the soybean crop and the benefits observed in several crops with the inoculation of Bacillus subtilis (soil free-living diazotroph), especially in the biological control of plants, production of natural antibiotics and protective effect against secondary soil phytopathogens (Araújo & Marchesi, 2009;Kuhn & Pascholati, 2010;Pavan et al, 2011;Jardin, 2015), in addition to growth and development of the root system, greater absorption of water and nutrients, it is inferred that the coinoculation with Bradyrhizobium and B. subtilis may favor the development of the crop and, therefore, the production and quality of its seeds (Hungria et al, 2013;Bishnoi et al, 2015;Singh et al, 2016;Tahir et al, 2017;Galindo et al, 2018).…”

The use of growth-promoting bacteria can increase the yield and quality of seeds of several annual crops, such as soybean. Based on that, the present study aimed to evaluate the effects of the inoculation of Bacillus subtilis strains on seed treatment, evaluating the yield and quality of seeds of two soybean cultivars. The experiment was conducted in a conventional system, in an Oxisol of clayey texture, in a crop under sprinkler irrigation. The experimental design was randomized blocks, arranged in split plots with four repetitions. Treatments were composed, in the plots, of two soybean cultivars: M7110 IPRO and Brasmax Desafio RR. Within the levels of subplots, the treatments consisted of inoculation and doses of inoculant: Bacillus subtilis Pant001 strain at doses of 0, 2, 3, 4 and 5 mL kg-1, and QST713 strain at the recommended dose of 2 mL kg-1. Inoculation with the strains Pant001 and QST713 increased the yield of both soybean cultivars tested, besides improving seed quality due to the increase in the concentration of total storage proteins, seedling emergence percentage and seed vigor by the accelerated aging test.

“…Estes dados corroboram com os resultados de Galindo et al (2018) que ao avaliarem a inoculação e coinoculação em duas cultivares de soja obtiveram rendimento de aproximadamente 600 kg ha -1 a mais que a inoculação e lucro 14,1% maior. Schneider et al (2017) obtiveram margem líquida superior a inoculação com B. japonicum independente da dose utilizada.…”

“…Essa combinação pode ser uma estratégia promissora para o aumento da produtividade, devido à combinação da FBN com a produção de fitormônios, a qual resulta em maior desenvolvimento radicular (HUNGRIA et al, 2015). Efeitos positivos sobre a produtividade da soja com o uso desta técnica já foram reportados por Schneider et al (2017), Galindo et al (2018).…”

O objetivo deste trabalho foi avaliar o efeito da inoculação e coinoculação de sementes de soja com diferentes bactérias fixadoras de nitrogênio, associadas ou não à adubação nitrogenada, sobre os componentes de produção, produtividade e acúmulo de nitrogênio da cultura da soja. O delineamento experimental foi blocos casualizados, com quatro repetições, em esquema fatorial 4 x 2, avaliando-se sem inoculação, inoculação com Azospirillum brasilense, inoculação com Bradyrhizobium japonicum e inoculação com Azospirillum brasilense + Bradyrhizobium japonicum, e dois níveis de adubação nitrogenada: controle sem nitrogênio, adubação com 90 kg ha-1. A maior altura de plantas foi verificada no tratamento com adição de 90 kg ha-1 e sem nenhuma forma de inoculação. O número de vagens e o número de grãos por vagem não foram afetados pela adubação nitrogenada, mas foram significativamente maiores nos tratamentos com Bradyrhizobium japonicum e com a associação de Azospirillum brasilense + Bradyrhizobium japonicum. Na ausência da adubação nitrogenada, a produtividade de grãos foi superior com a coinoculação, e na presença de adubação nitrogenada a produtividade foi estatisticamente igual, sendo, portanto, a coinoculação sem adubação nitrogenada o melhor tratamento, devido ao menor custo. Houve um lucro 12% maior da coinoculação em relação a inoculação, sem a adubação nitrogenada.

“…The use of microorganisms in agriculture, such as Azospirillum brasilense, and the cultivation of cover crops before the harvest of soybean and maize, have been interesting alternatives to increase grain yield and foliar N concentrations in crops (Aguiar et al, 2011;Cangahuala-Inocente et al, 2013;Galindo et al, 2018). Kappes et al (2013) reported 9.4% increase in grain yield of maize inoculated with A. brasilense, without topdressing N fertilization.…”

The use of microorganisms in agriculture such as Azospirillum brasilense and the cultivation of cover crops in the off season, together with nitrogen fertilization, may be interesting alternatives to increase crop yield. The objective of this study was to evaluate the growth, production and nitrogen concentration of maize grown in succession to cover crops and their interactions with A. brasilense inoculation and topdressing mineral N fertilization. The experiment was conducted on Oxisol, in randomized block design in split-split-plot scheme with four repetitions. The plots consisted of four cover crops: jackbean (Canavalia ensiformis), dwarf pigeon pea (Cajanus cajan), crotalaria (Crotalaria spectabilis) and spontaneous vegetation. In the subplots, with or without inoculation of A. brasilense in maize seeds, and in the sub-subplots: with or without topdressing N fertilization. It was verified that jackbean can generate increments of up to 8.3% in grains per ear, 6.9% in length of ear and 15.2% in mass of one hundred grains. Consequently, the grain yield was higher in this treatment (18%). The inoculation with A. brasilense and topdressing N fertilization did not generate significant increments in maize production components, as observed for cover crops.
