This research work presents the results of studies of the effect that pre-sowing seed treatment and spraying nitrogen-fixing, phosphate- and potassium-solubilizing bacteria on the seedlings of the Primorskaya 39 spring soft wheat (Triticum aestivum L .) variety have on the structure elements of productivity, yield and the number of soil microorganisms. It was established that the total number of bacteria increases in the middle dough stage when using both pre-sowing treatment of seeds and spraying microorganism strains on the seedlings. The maximum number of bacteria in the soil was revealed in the variant using strains of nitrogen-fixing and potassium-solubilizing microorganisms in pre-sowing treatment (1.9×107 cfu/g of soil) and phosphate- and potassium-solubilizing in spraying seedlings (2.0×107 cfu/g of soil). The variant a1+c2+f6 showed the highest content of mobile phosphorus (92 mg/kg) after pre-sowing treatment with nitrogen-fixing, potassium- and phosphate-solubilizing microorganisms in the middle dough stage. High yield (4.3 t/ha) was shown by the variant a1+f19 after pre-sowing seed treatment with nitrogen-fixing and phosphate-solubilizing strains.
