The importance of biotechnology involved in the availability of nutrients to plants in different production systems is well known. In the search for agricultural sustainability, biological nitrogen fixation process stands out, especially in tropical regions where soil organic matter can be rapidly mineralized. In this aspect, researches have pointed out the potentialities of the use of diazotrophic bacteria, as well as other growth-promoting bacteria in Poaceae. Maize crop, especially, stands out in the international scenario, requiring a deepening of the research aiming to raise the contribution potential of microorganisms including Azospirillum spp. in reducing the consumption of fertilizers from nonrenewable sources while promoting an increase in agricultural productivity and mitigating environmental impacts.

“…In maize crops, the use of Azospirillum brasilense and Bacillus subtilis has contributed to reducing the amount of industrial nitrogen fertilizer used as topdressing by 50 to 80% and heightened its effect when applied only at sowing (Lima et al, 2011;Dartora et al, 2016;Garcia et al, 2017;Mumbach et al, 2017;Picazevicz et al, 2017). These rhizobacteria can enhance zinc availability to crops by solubilizing this micronutrient, which is easily adsorbed by the soil, making it unavailable to plants before root development (Goteti et al, 2013;Mumtaz et al, 2017).…”

Rhizobacteria have a wide range of plant growth-promoting mechanisms of action, making them an alternative and/or complementary biological input for chemical fertilizers. In this respect, the present study aimed to assess growth and nitrogen accumulation in maize plants as a function of Azospirillum brasilense, Bacillus subtilis, zinc and nitrogen application at sowing. The experiment with the ‘AL Bandeirante’ maize variety was conducted in a greenhouse, using a completely randomized design. The treatments were arranged in a 2 x 2 x 2 x 2 factorial scheme, with six repetitions, considering the presence and absence of Azospirillum brasilense (5 g kg-1), Bacillus subtilis (5 mL kg-1) and zinc (20 g kg-1) in the seeds and addition or not of nitrogen (30 kg ha-1) to the soil. The variables assessed were plant height, stem diameter, leaf, stem, shoot, root and total dry weight, and shoot nitrogen content. Nitrogen fertilization in the absence of zinc increased shoot and total dry weight as well as shoot nitrogen content. Zinc applied to the seeds improved the total and stem dry weight of maize plants in the absence of Bacillus subtilis. Inoculation with Azospirillum brasilense and Bacillus subtilis increased the stem diameter and shoot nitrogen content of maize plants when nitrogen fertilization was not performed at sowing. There was no isolated or interaction effect between factors for plant height and root dry weight.
