“…The bacterial genus Pseudomonas includes several species with activity recognized as PGPB (ANTOUN & PRÉVOST, 2005). The use of this bacterium in corn has been highlighted by OLIVEIRA et al (2015). In 2017, the efficacy of a Pseudomonas fluorescens-based inoculant was proven in corn, which led to its approval as a growth promoter for this crop (Product Registration PR-93923 10104-7).…”

The evaluation of plant growth-promoting bacteria in order to increase corn productivity is a biotechnology of global interest. This study evaluated the efficiency of the consortium between P. fluorescens CNPSo 2719(=CCTB03) and A. brasilense Ab-V06 in corn. Four experiments were carried out in four different locations, with a randomized block design and four replications, with the treatments: (1) without inoculation and without application of N coverage; (2) without inoculation and application of 100% of the recommended dose of N in coverage (200 kg ha-1 of N); (3) Azospirillum brasilense + application of 75% of the recommended dose of N in coverage (150 kg ha-1 of N); (4) bacterial consortium of Azospirillum brasilense + Pseudomonas fluorescens + application of 75% of the recommended dose of N in coverage (150 kg ha-1 of N). In all locations, with the use of the bacterial consortium (A. brasilense + P. fluorescens) + 75% of the recommended dose of N in coverage, it was possible to reduce the dose of N in coverage by up to 25% without compromising the productivity of the crop. In this way, it is concluded that the use of the consortium of the two bacteria promotes savings of up to 25% of N fertilization in top dressing and the possibility of using two microorganisms with the capacity to stimulation plant growth with a single application.

“…Em especial, Pseudomonas fluorescens, é uma espécie estudada, onde os relatos benéficos para a agricultura, vem demonstrando que influenciam sobre o controle alguns fitopatógenos nocivos, produzindo grupos de metabólitos especiais antipatogênicos e com capacidade de solubilizarem fontes de fosfatos não lábeis que os vegetais não podem acessar, por estarem retidos no solo. Esses são alguns dos diversos benefícios de se estudar e usar essas bactérias promotoras em grandes quantidades (Oliveira et al, 2015;Kazi et al, 2016).…”

Dentre os microrganismos promotores de crescimento de plantas, podemos destacar os gêneros Azospirillum e Pseudomonas. Esses grupos de microrganismos podem aumentar o crescimento, desenvolvimento e rendimento de várias espécies de plantas de interesse agrícola. O objetivo deste estudo, foi verificar a eficácia e a influência do produto comercial Biofree® a base de Pseudomonas fluorescens e Azospirillum brasilense aplicados via foliar na cultura do sorgo. O experimento foi desenvolvido no Centro Agro Pesquisa no Cerrado, Rio Verde, Estado de Goiás, Brasil (S 17º44'54" e W 50º51'13"). Os tratamentos foram constituídos por diferentes doses 0,0; 0,3; 0,5 e 0,7 L ha-1 de Biofree® aplicado via foliar em V4/V5. Foram determinadas as variáveis altura de plantas, tamanho da panícula, estande de plantas e produtividade de grãos. Os dados foram submetidos a análise de variância ANOVA e os casos de significância foram submetidos ao teste de média Scott-Knott p < 0,05. A aplicação de Azospirillum brasilense e Pseudomonas fluorescens (Biofree®) promoveram incrementos na produtividade de grãos de sorgo cultivar Nucover 100.
