EVALUATION OF Azospirillum brasilense DOSE RESPONSE ON FRESH AND DRY MATTER OF SHOOT AND ROOT OF CORN PLANTS 196
do Amaral Júnior, Wellington Elias; Rodrigues Esteves, Flávia; Pereira de Menezes Filho, Antonio Carlos; Abadia Ventura, Matheus Vinicius.
Zea mays (corn) is one of the leading crops focused on producing food and feed for humans and animals. The use of diazotrophic bacteria such as Azospirillum brasilense demonstrates a positive effect on nitrogen availability, a primordial element for the development of this plant. This study aimed to evaluate the gain of the fresh and dry matter of shoots and roots in a corn cultivar inoculated with A. brasilense at different doses. The experiment was carried out in pots containing soil. The corn seeds, cultivar Agroceres® 5055, were inoculated with A. brasilense at doses between 100 to 250 mL 20 kg-1. It was observed that inoculation with A. brasilense positively affected fresh and dry matter gain of both shoot and roots between doses of 100-200 mL 20 kg-1...

Nitrogen translocation in wheat inoculated with Azospirillum and fertilized with nitrogen PAB
RODRIGUES,OSMAR; DIDONET,AGOSTINHO DIRCEU; GOUVEIA,JORGE A.; SOARES,RITA DE CÁSSIA.
The productivity and the translocation of assimilates and nitrogen (N) were compared after inoculation of wheat (Triticum aestivum L., cv. BR-23) seeds with two strains of Azospirillum brasilense (strains 245 and JA 04) under field conditions. The inoculation of wheat seeds was done with a peat inoculant at sowing time. Plant material for evaluations were collected at anthesis and maturity. No differences in grain yield and in the translocation of assimilates resulting from inoculation were detected. Differences were observed in relation to N rates (0, 15, and 60 kg ha-1). N content in the grain increased significantly in the bacteria-inoculated treatments in which N was not added. This increase in N content in the grain with inoculation was probably due...
