Nitrogen fixation is one of the most important fundamental processes in crop production, which ensures nitrogen circulation in nature, which affects the biological productivity of plants. The intensity of the symbiotic process and the duration of its work are one of the main factors in shaping the productivity of leguminous plants, and as a result, their yield level. When developing modern intensive pea cultivation technology, the key task is to create the most optimal conditions for the formation of a powerful symbiotic potential, long-term active work of nodule bacteria and accumulation of a high level of biological nitrogen. This scientific work summarizes the results of field research on the effect of the Anderiz inoculant developed on the basis of active strains of nodule bacteria Rhizobium leguminosarum, the mycorrhiza-forming drug Mycofriend created on the basis of Glomus sp. and complex fertilizer based on potassium humate with Gumifrend microorganisms on the symbiotic productivity of pea crops for their varied use, namely on the number of active nodules on plant roots, the formation of active symbiotic potential and the amount of biologically fixed nitrogen. Field research was carried out during 2019-2021 in the conditions of the experimental field of the Agronomic Research Center of VNA on gray forest medium-loamy soils.  Based on the results of the research and the analysis of the obtained data, it was established that the most productive was the variant of the experiment that provided for the pre-sowing treatment of seeds with the inoculant Anderiz (2.0 l/t) in combination with the mycorrhizal preparation Mycofriend (1.5 l/t) and two foliar top dressings with a complex fertilizer on the basis of Gumifrend potassium humate (1.0 l/ha) on the background of mineral fertilizer N30Р60К60. On this variant, the formation of the maximum amount of biologically fixed nitrogen in the experiment was recorded in the Deviz variety - 48.6 kg/ha and in the Tsarevich variety - 56.3 kg/ha.
