The humified organic matter presents bioactivity similar to the auxinic effect. As bokashi is produced by a specialprocess of humification, information is needed about the bioactive potential of its humic acids. The objective of this
work was studying the initial performance of corn-indicator plants in response to the application of different
concentrations of humic acids isolated from bokashi. The corn seeds were treated for 16 hours with solutions containing
0, 10, 20, 30, 40 and 80 mmol L-1 of C in the form of humic acids. Then, the seeds were planted in pots of 1 dm3 containing
corrected and fertilized soil, in greenhouse. Growth characteristics of shoot and root systems were evaluated. The
results showed that the humic acids extracted from bokashi had positive effects on the initial performance of corn.
