Summary. The role of mixed sowing of leguminous crops is becoming indispensable and the reduction in the nutritional feed value is a serious problem in animal husbandry.

The aim of the study was to evaluate the impact of pre-sowing seed treatment with biofertilizers and ultrafine particles on the productivity of mixed sowing of annual crops.

The seeds were treated with ultrafine particles of SiO2 (100 g/t); MoO2 (100 g/t); Fe3O4 (100 g/t), Ribav Extra (10 ml/t) and Agroverm (1 l/t). The ratio of crops is 1:2:1, respectively, peas: barley: millet. Data on the productivity of the green mass were recorded at the time of harvesting, the highest result was shown by the variant using SiO2 UFP, both in separate and mixed sowing, and amounted to 24.8 t/ha, 20.3 t/ha, respectively. The dry matter content in separate seeding exceeded the control variant in peas in the Fe3O4 UFP variant by 12%; millet in the SiO2 UFP variant by 7.4% and barley in the MoO3 variant by 1.7% (Р≤0.05).

The use of the method of gluing seeds with the introduction of UFP slightly affected the amount of dry matter, the largest difference of 1.1% (P≤0.05) was found when using Fe3O4 UFP.

Key words: green mass, barley, millet, peas, microfertilizers, SiO2, MoO2, Fe3O4, Ribav Extra, Agroverm, productivity.
