The effectiveness of soybean-rhizobial systems formed by a bacterial suspension, containing Bradyrhizobium japonicum RS07 strain and soybean seed lectin, with soybean plants of the Diadema Podillia variety was studied under conditions of pot experiment with a sand culture, after seed treatment with Maxim XL and Standak Top seed protectants. A tendency to increase the plant height was revealed when lectin was added to the bacterial suspension both in the variant without treatment with fungicides and with their use. The growth of above-ground mass in the stage of bean formation was facilitated by the use of lectin against the background of treatment with the fungicide Maxim XL. It was established that at the initial stages of the symbiosis formation, the tested protectants, regardless of the presence of lectin in the inoculation suspension, favorably influenced the nodules formation, while the nodules mass was mainly at the control levels. The use of a homologous lectin had a positive effect on the symbiosis functioning at the initial stages of soybean plant development. At the same time, the treatment of seeds with the fungicide Maxim XL did not have a toxic effect on this process, in contrast to Standak Top, where the nitrogen-fixing activity was lower by 16.6 %. However, in the second half of the soybean vegetation, this index under the Standak Top application exceeded the control plants by 36.8 and 21.8 % at the flowering and bean formation stages, respectively. In all studied treatments, a tendency to increase the grain productivity was revealed. The use of lectin on the background of treatment with fungicides Maxim XL and Standak Top contributed to an increase in the grain weight by 9.6 and 10.0 %, respectively. The obtained results regarding the effect of fungicides and lectin on the formation and functioning of symbiotic systems, and soybean productivity confirm the possibility of their use in the cultivation technology of this crop.
