THE INFLUENCE OF BACTERIAL INOCULATS ON PATHOGENS, YIELD AND QUALITY IN SOYBEAN CROP

Abstract

The paper aimed to present the influence of bacterial inoculation,applied to seeds, on the attack of pathogens, on yield, yield elements and quality in soybean crop.A two-year experiment was carried out at Research and Development Station for Agriculture Turda (RDSA Turda), in 2019-2020. Teo TD, an early soybean variety was used in the experiment. Seed stimulation was conducted with two nitrogen-fixing bacteria: Bradyrhizobium sp. JHI and Paenibacillus graminis FL400. The application of bacterial inoculants leads, in the second year of experiment, to an increase in soybean yield with 903 kg/ha, 39.8% higher compared to the control, when Bradyrhizobium + Paenibacillus was applied. Biostimulation also help the plant fight against pathogens with a positive impact on number of nodules, yield elements and quality parameters.
