Abstract
This paper presents the study results on the effect that presowing seed treatment and spraying nitrogen-fixing, phosphate-, and potassium-solubilizing bacteria on the seedlings of the Primorskaya 39 spring soft wheat (Triticum aestivum L.) cultivar have on the structural elements of productivity, yield, and the number of soil microorganisms. It was found that the total number of bacteria increases in the waxy ripeness stage when using both presowing treatment of seeds and spraying the microorganism strains on the seedlings. The maximum number of bacteria in the soil was detected in the variants when using strains of nitrogen-fixing and potassium-solubilizing microorganisms in presowing treatment (1.9 × 107 CFU/g of soil) and phosphate- and potassium-solubilizing microorganisms when spraying the seedlings (2.0 × 107 CFU/g of soil). The variant N1 + K2 + P6 after presowing treatment with nitrogen-fixing, potassium-, and phosphate-solubilizing microorganisms in the waxy ripeness stage showed the highest content of mobile phosphorus (92 mg/kg). High yield (4.3 t/ha) was shown by the variant N1 + P19 after presowing seed treatment with nitrogen-fixing and phosphate-solubilizing strains.
