| Summary: | The objective of this study was to evaluate the effect of inoculation of Bacillus subtilis and
Azospirillum brasilense on growth and yield of corn. The experiment was conducted in the
municipality of São Jorge Ivaí during the period April to August 2013 in outlined in a randomized
block design with five treatments and four replications. T1 - Control; T2 - Bacillus subtilis
suspended in water (1 L ha-1) at sowing; T3 - Bacillus subtilis powder (1 kg ha-1
) inoculated seeds;
T4 - Azospirillum (100 mL ha-1
) inoculated seeds; T5 - Azospirillum (100 mL ha-1
) + Bacillus (1 L ha-1
)
in the groove. Analysis of nematodes in the roots of corn, fresh weight of shoots, ear weight and
plant height were performed and evaluated crop yield. Sisvar the program to conduct statistical
analysis was used. For the analysis of variance F and Tukey test (5%) for comparison of means was
used. There was no population control of plant nematodes evaluated during the experiment. The
use of Bacillus subtilis has supported development of the fresh weight of shoots in approximately
15% of corn in the off-season cultivation. The use of Azospirillum brasilense in the seeds increased
by 21.9% corn yield compared to the control treatment
