Abstract. The microbiological preparation BIO–ONE is a 100% natural liquid concentrated microbiological product providing 20 kg of active nitrogen/decar. It facilitates the absorption of the residual phosphorus and potassium and retains moisture. BIO–ONE does not contain genetically modified organisms. It is recognized by all organizations controlling the organic farming, including OMRI Institute. It could be used both in organic and traditional agriculture. With its gradual application in soil the microbiological preparation BIO–ONE contributes to increasing soil organic matter and also protects it from wind erosion. The application of the microbiological preparation BIO–ONE helps for obtaining the maximum efficiency of the used mineral fertilizers. The microbiological preparation BIO–ONE has a positive impact on the yield of peas seeds. After treatment of the crop with the microbiological preparation BIO–ONE the highest yield was obtained at a dose of treatment of 0.9 g/100 m2–185.0 kg/da, followed by the variants treated at a dose of 0.12 g/100 m2–167.0 kg/da and 0.6 g/100 m2–165.0 kg/da. At the lowest dose of treatment of 0.3 g/100 m2 and the fertilized control the yield was equal–158.0 kg/da. The lowest yield was obtained from the control variant. It increases the wheat yield as after–effect after treatment of peas at concentration of 0.6 to 0.12 g/100 m2 as the wheat yield is raised by 43 kg/da compared to the untreated control. The highest yield was obtained for the variant of peas fertilized with N4P8–as the yield exceeded by 57 kg/da the control that was not fertilized and treated. It is noticed also that at lower doses of treatment the quantity of siftings is lower as it goes up at higher doses of treatment.
