Abstract: Recently, much attention has been paid to the problem of ecological farming in agricultural produc tion due to the increased interest in the production of safe products. The article presents the results of analyzing the dynamics of soil enzyme activity of hydrolases and oxidoreductases class at pre-sowing inoculation of winter triticale seeds (X Triticosecale Wittm. ex A. Camus) of the Bilinda variety with complex microbial preparations based on associative diazotrophic microorganisms. The following microbial preparations were used in the experiment: Flavobacterin (Flavobacterium sp., strain 30), Mizorin (Arthrobacter mysorens, strain 7), Agrophil (Agrobacterium radiobacter, strain 10), Rizobact RZHF (Corynebacterium sp., strain PBT 7) and FZHF (Pseudomonas sp., strain PBT 4). Soil samples were collected at three dates, which corresponded to the phases of booting, earing and wax ripeness. An increase in the urease activity was detected in the wax ripeness phase. The maximum level of the enzyme was recorded in the variants with application of Flavobacterin (30.7 mg NH3 per 10 g of soil) and Rizobact FZHF (30.2 mg NH3 per 10 g of soil). In the same phase, maximum phosphatase values were observed in the variant with application of Mizorin (2.9 mg P2 O5 ), and invertase in the variants with application of Agrophil (15.6 mg glucose) and Rizobact RZHF (16.7 mg glucose). The highest concentration of catalase was observed at the earing phase when Agrophil and Flavobacterin were used (respectively 3.8 and 3.4 ml of O2 released in 2 min per 1 g of soil). High rates of plant height and ear productivity were obtained in the variant with inoculation with Flavobacterin preparation. The increase relative to the control in this case amounted to: by plant height – 5.63%, by ear length – 5.3%, by number of grains – 16.7%, by grain weight per ear – 41.4%.
