The article reflects the results of studies (2017-2019) on the study of the treatment of pea seeds before sowing with complex micronutrient fertilizer Aquamix, containing in a chelated form elements and inoculation with rhizotorphin for the yield, quality and formation of a symbiotic apparatus in pea varieties differing in the architectonics of the leaf apparatus (leafy, leafletless, with canopy heterophyllia - chameleons and lupinoids). The positive effect of seed treatment before sowing with Aquamix and seed inoculation on the productivity of peas has been established. The increase in yield reached 4-9%, with a yield in the control of 2.1-2.3 t/ha. Better than others, the leafy pea variety Temp and the variety with canopy heterophyllia Spartak responded to seed treatment. Treatment of pea seeds before sowing increased the protein harvest with grain yield by 0.2- 0.5 c/ha (4-11%). The highest increase in protein yield was provided by the Spartak variety. It was shown that inoculation of pea seeds before sowing with rhizotorphin and treatment with Aquamix had a positive effect on the formation of a symbiotic apparatus. The maximum mass of nodules was formed during the shoot phase (7 leaves) of peas. In the budding phase, the mass of nodules decreased in all variants by 1.3-4.0 times, and by the beginning of flowering on the Pharaon, Temp and Spartak varieties, almost complete destruction of nodules occurred, and only in the Lu-153-06 (lupinoid) line, the mass of nodules along experimental variants ranged from 11 to 13 mg per plant. Analysis of economic indicators showed that the maximum net income was obtained on options with seed treatment. At the same time, the level of profitability ranged from 108 to 126%
