The paper presents the research results of influence of biopreparations Rhizohumin and Polimiksobakterin on the different backgrounds of mineral nutrition in North Steppe regions of Ukraine. The positive influence on the pea productivity of both of nitrogen fixing and phosphorus mobilizing preparations was shown. The highest yield indices – 3,23-3,27 and 2,38-2,49 t/ha of Tsarevich and Kharkov standard cultivars was achieved under the use of Rhizohumin or Polimiksobakterin and mineral fertilizers background in the dose of N 40P40K40. on growing processes of pea.
