| Bactérias dos gêneros Azospirillum e Herbaspirillum são fixadoras de nitrogênio (N) atmosférico e consideradas promotoras do crescimento vegetal. Desta forma, desenvolveu-se o presente trabalho com o objetivo de avaliar o desenvolvimento e a produtividade do milho em resposta à inoculação de A. brasilense e H. seropedicae associada à adubação nitrogenada. O experimento foi conduzido em delineamento experimental de blocos ao acaso em esquema fatorial 4 x 5, com quatro repetições. Os tratamentos foram constituídos da inoculação de sementes (testemunha, estirpe de A. brasilense - Ab-V5, estirpe de H. seropedicae - SmR1 e combinação Ab-V5 + SmR1) e doses de N (0, 40, 80, 120 e 160 kg ha-1 de N). Foram avaliados: diâmetro basal do colmo, altura de planta,... |

| ABSTRACT Bacteria from the genera Azospirillum and Herbaspirillum have been associated with increments in maize yield. The aim of this study was to evaluate the maize yield and nutritional content in response to inoculation with A. brasilense and H. seropediceae in association with nitrogen (N) fertilization. The experimental design was randomized blocks in a 4 x 5 factorial scheme, with four replicates. The treatments consisted of seed inoculation (control without N and inoculation, A. brasilense strain - AbV5, H. seropediceae strain - SMR1 and co-inoculation AbV5 + SMR1) and N doses (0, 40, 80, 120 and 160 kg ha-1). The following variables were evaluated: ear insertion height, ear length, ear diameter, number of rows per ear, number of grains per row,... |

| ABSTRACT The aim of this study was to evaluate the response of maize to inoculation with strains of plant growth-promoting bacteria (PGPB) in two cultivation years. The experiment was set in a randomized block design with four replicates in two cultivation years (2012/13 and 2013/14). The treatments consisted of PGPB inoculation: control (without N and without inoculation); 30 kg of N ha-1 at sowing (N1); 160 kg of N ha-1 (N1 + 130 kg of N ha-1 as top-dressing); N1 + A. brasilense, Ab-V5; N1 + A. brasilense, HM053; N1 + Azospirillum sp. L26; N1 + Azospirillum sp. L27; N1 + Enhydrobacter sp. 4331; N1 + Rhizobium sp. 8121. Basal stem diameter, plant height, leaf area, shoot dry matter and yield were evaluated. The strain of Rhizobium sp. 8121and the isolate... |
