Abstract The paper presents the results of studies on the impact of different standards herbicide Fabian (90, 100 and 110 g/ha), the methods of application of plant growth regulators Rehoplant (250 ml/m – preplant processing of seeds, 50 ml/ha – spraying) and microbiological agents Ryzobofit (preplant processing of seeds – 100 ml/t) on the formation and symbiotic functioning system of soybean plants. It was established that the processing of soybean crops of different rates of Fabian herbicide separately and in mixtures with the plant growth regulator Rehoplant as on the background of presowing of seed with mixture of Rehoplant and Ryzobofit, and without it inhibits the formation of nodules on the roots of plants. However, the formation of their weight depends on the norms and ways of using of investigational preparations. It was found that complex application of preparations stimulates accumulation of leghemoglobin in soybean nodules.
