The influence of soybean rhizobia on the agricultural seeds sowing qualities

To grow high and stable yields with good product quality, it is very important to receive timely, full-fledged and friendly shoots of optimal density. Therefore, the problem of stimulating, or inhibiting, seed germination and the processes occurring in them occupies an important place in modern crop production. The method of pre-sowing seed treatment with rhizobia is one of the promising technological measures that ensure an increase in yield and quality of crop production. The staff of the Laboratory of Biological Research of the Federal State Budgetary Budgetary Institution of the Federal Research Institute of Soy conducted a study of the possibility of stimulating germination and disinfection of soybean seeds, lupin, vigna, wheat, barley using pure Sinorhizobium fredii crops. The work used collectible strains of rhizobia, which showed an abundant growth of bacterial mass on the nutrient medium of the MRC. The standard strain was S. fredii 5851 from the collection of microorganisms and cell cultures of the Leibniz Institute (DSMZ), Germany. In variants with strains, stable stimulating and healing effects were observed. As a result of a scientific experiment, it was found that, on average, in variants with S. fredii strains, germination increased by 37%, the length of seedlings – by 224%, the raw weight of seedlings – by 23% compared with the control (without treatment with strains). S. fredii strains BB-49, SB-39, SB-43, TB-422, TB-488, TB-490, TB-496, 062 maximally stimulated the process of germination of agricultural seeds.
