The formation of nitrogen-fixing root nodules, plant mass and soybean yield under the use of post-emergence herbicides and their combinations with plant growth regulator Athonic Plus and mіcrofertilizer Nanomix was studied. It was established that application of tank mixtures of post-emergence herbicides had led to the reduction of number and mass of nitrogenfixing nodules on the roots of soybean plants. Application of the Athonic Plus and Nanomix preparations, on the contrary, had promoted studied indices. The maximum soybean yield was observed in the variants with tank mixtures of herbicides Nabob + Fabіan + Mіura and Nabob + Fusillade Forte 150 EC. Combination of Athonic Plus and Nanomix preparations with post-emergence herbicides had resulted in the reduction of the herbicides efficiency against weeds, which had prevented to unleash high yield potential of the crop.
