“…However, the increase in grain yield, independently of forms of inoculation, was equivalent to 16.1% compared to control. Similar results were reported in the literature where wheat yield was between 3.1% and 11.1% greater in inoculated plants compared with non-inoculated plants [10,[56][57][58]. Fukami et al [11] reported that spray inoculation with A. brasilense either on leaves or soil can increase plant growth and can replace 25% of N fertilization on grasses.…”

The use of biological techniques such as plant growth-promoting bacteria (PGPB) can represent a sustainable alternative for cereal growth in tropical areas. Research showing the potential for management practices which optimize PGPB inoculation is of utmost importance. This research was developed to investigate the potential use of Azospirillum brasilense in wheat cropping systems, as well as to assess the potential synergistic interactions between the beneficial use of silicon (Si), principally under abiotic and biotic conditions, and A. brasilense forms of application and how they impact crop development and wheat yield. The study was set up in a Rhodic Hapludox under a no-till system. The experimental design was a completely randomized block design with four replicates arranged in a factorial scheme with four inoculation forms (control, seed, groove, and leaf) and two soil acidity corrective sources (Ca and Mg silicate as Si source and dolomitic limestone). Seed inoculation was more effective in promoting wheat growth and development, with higher yield, showing an increase of 26.7% in wheat grain yield. Calcium and magnesium silicate application associated with foliar inoculation and without A. brasilense inoculation can increase wheat grain yield.

“…Quanto ao sistema radicular, observou-se que a inoculação de A. brasilense promoveu aumento do comprimento das raízes da cevada, porém não influenciou no volume e na massa seca das raízes (Tabela 7). Esses efeitos podem estar associados a capacidade da bactéria em promover o aumento da disponibilização de alguns nutrientes para as plantas, como o nitrogênio e o fósforo, o que pode ter promovido o crescimento radicular (GALINDO et al, 2016;GALINDO et al, 2017). De acordo com Silveira et al (2016), a inoculação com A. brasilense promove o crescimento das raízes de trigo, pela capacidade das mesmas em sintetizar ácido indolacético e fixar nitrogênio.…”

“…Na cultura do trigo, a inoculação da bactéria melhorou o teor de clorofila e promoveu o peso das raízes (SILVEIRA et al, 2016), aumentando a altura das plantas e o número de grãos por espiga da cultura (ALVES et al, 2017). No milho, essa bactéria pode aumentar a produtividade de grãos (MORAIS et al, 2016).…”

RESUMOA competição exercida pelas plantas daninhas, como o azevém, destaca-se como um limitante ao desenvolvimento da cevada. O uso de inoculantes à base de bactérias promotoras de crescimento pode se tornar uma alternativa para melhorar o desenvolvimento das plantas e seu potencial competitivo. Dentre as principais encontra-se o gênero Azospirillum que é caracterizada como fixadora de nitrogênio. Objetivou-se avaliar a eficiência da inoculação de estirpes A. brasilense e de densidades de azevém nos estádios iniciais da cultivar BRS Korbel. Utilizou-se delineamento inteiramente casualizado, sendo que os tratamentos utilizados foram: inoculação ou não de Azospirillum brasiliense (primeiro fator) e populações de azevém (segundo fator). Durante a fase vegetativa da cultura foram realizadas as quantificações de estatura das plantas, teor de clorofila (índice SPAD), perfilhamento, massa seca da parte aérea e raiz, comprimento das raízes e volume de raízes. Da espécie daninha foram avaliados o número de perfilhos e massa seca da parte aérea. Através dos dados realizou-se a análise estatística (Duncanp≤0,05). A inoculação favoreceu o perfilhamento e comprimento radicular da cultura. O aumento das populações da daninha acarretou na redução das variáveis: altura, perfilhamento, teor de clorofila, comprimento, volume e massa seca das raízes da cevada. A inoculação não contribui para a elevação da competitividade da cultura.

“…Soybean (Glycine max (L.) Merrill) occupied 35,866 million hectares in the 2018/2019 season, with average grain yield of 3,207 kg ha -1 (CONAB, 2019). To obtain high yields of soybean grains and considering the nitrogen (N) demand of this crop, the biological fixation of N must work at maximum efficiency (Galindo et al, 2017;Moretti et al, 2018). In this context, the use of new technologies seeking to increase seed yield and quality becomes essential for the competitive agriculture and low carbon emissions (Sá et al, 2017).…”

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.
