Sugarcane is an essential crop in the Brazilian economy. The adoption of techniques acclimatization plants vitro contributes to success field. present work aims evaluate effect Azospirillum brasilense on sugarcane seedlings. experiment was conducted with six treatments and twelve replications. There were two control without inoculation, one N fertilization without, four A. (2.0x108 CFU) at diff...

Although Azospirillum strains used in commercial inoculant formulations presents diazotrophic activity, it has been reported that their ability to produce phytohormones plays a pivotal role in plant growth-promotion, leading to a general recommendation of its use in association with regular N-fertilizer doses. In addition, a high variability in the effectiveness of Azospirillum inoculants is st...

In this paper the problem of parameter identification for the Monod model is considered. As known for a long time, noisy batch measurements do not allow unique and accurate estimation of the kinetic parameters of the Monod model. Techniques of optimal experiment design are, therefore, addressed to design informative experiments and improve the parameter estimation accuracy. During the design pr...

Given the hypothesis that co-inoculation with plant growth-promoting bacteria (PGPB) enhances beneficial effects of Rhizobium tropici greater mineral nutrition, optimizes biological nitrogen fixation and reduces use fertilizers in bean plants, objective this research was to evaluate synergistic associated Azospirillum brasilense, Bacillus subtilis, Pseudomonas fluorescens their combinations, on...

The objective of this study was to evaluate sorghum hybrids associated or not with Azospirillum brasilense and nitrogen fertilization (N) during planting on the yield, fermentative profile, nutritional value respective silages. Five (Volumax, 201813B, 201814B, 201709B, BRS716) were evaluated three strategies using urea (100 kg ha−1 N) brasilense, N)/A. in association. A randomized block design ...
