Inoculação de Azospirillum Brasilense em milho para silagem e grãos

Abstract

Inoculation of Azospirillum brasilense bacteria is aimed at reducing costs and increasing productivity in corn. The mechanism of by producing phytohormones by bacteria that stimulate the absorption of nutrients by the plant. The aim of this study was to evaluate the development of maize destined for the production of silage and grains, subjected to different concentrations inoculant containing A. brasilense. The inoculant was used under the tradename AzoTotal® with AbV5 and AbV6 strains. In the control sample was not added inoculant  then 80g / ha, 160g / ha to 240g / ha in each line, a total of four treatments. The experimental design was in blocks with four treatments and three replications. The blocks were represented by four lines measuring four meters in length. In the evaluations, there was a proportional increase in the number of rows of grain in the ear. The quantity of grains per row, the highest value obtained was 30 grains obtained with a concentration of 160 g / ha. In the amount of grains of corn, there was an average of 451.83 grains range of ± 20 grains, with 471.09 being the highest value obtained in line with 240g / ha of inoculant.
