The article deals with microbiological fertilizers “Azotovit” and “Fosfatovit” on field pea plants. Seeds were inoculated before sowing to study the effect on the agronomic traits in pea and the seed quality. A significant increase in germination energy (6.1-6.3%) was observed with the combined application of both highly mentioned microbiological fertilizers. Seed germination in the experimental groups ranged from 98.2-99.3%, with 95.4% in the control one for the Fokor variety and 95.7% for the Yubilyar variety. The increase compared to the control options ranged from 2.5 to 3.7%. “Azotovit” and “Fosfatovit” shortened the growing season of pea plants, that made it possible to harvest the pea crops earlier. Pre-sowing fertilization of pea crops improved the yield indicators and increased: the plant height by 5.4-14.3 cm; the length of beans by 0.8-1.2 cm; the number of internodes by 1.0-2.6 pcs.; the number of seeds in the bean by 0.7-10 pcs.; the weight of seeds from one pea plant by 0.1-0.3 g; the weight of 1000 seeds by 10.5-16.4 g and the seed yield by 6.3-12.5 g/l. Combined application of the Azotovit” and “Fosfatovit” microbiological fertilizers significantly increased pea yield by 16.5-24.4% compared to the control.
