Ensaio sobre a ação de inoculantes biológicos de Azospirillum brasilense em Triticum aestivum

Abstract

The way in which traditional agriculture has been using agricultural inputs for production on a larger scale has worried the population about its effects and thus promoting research in the field for alternatives that increase agricultural production without harming the environment and human health. This work aimed to evaluate different concentrations of Azospirillum brasilense inoculum on germination and development of wheat as growth promoters. The experiment was divided into two stages, one manipulated germination in the laboratory and the other simulated conventional planting, both applied water and different concentrations of Azospirillum brasilense inoculum. The variables analyzed were germination rate (TG), germination speed index (IVG), mean germination time (AMT), fresh biomass of shoots and roots, and dry biomass of shoots and roots, plant height and number of plants. average number of leaves per plant. In general, the results did not align for a specific concentration, each treatment showed efficiency in a different parameter. For the Germination Rate, Average Germination Rate, Fresh Phytomass of the Root of the germination test and the number of leaves in the planting, there was no significant difference. The results of the present work showed efficiency in the dry phytomass, both of the roots and of the shoot, in the germination and planting tests, with a result of a better efficiency with the treatment of 5% of the other tests.
