- Abstract
The experiments were performed in 2017-2018 in the fields of the Omsk Agrarian Scientific Center (Omsk, Russian Federation), with winter cereals as fore corp. The objective was to study and isolate strains of varietal-specific nodule bacteria that positively affect the development of soybean plants and nitrogen-fixing nodules. The experiment included soybean varieties of northern ecotype of the Omsk ASC selection: Zolotistaya and Cheremshanka. The seeds of cultivars were processed before sowing with microbiological fertilizers – four experimental varietal-specific isolates of nodule bacteria created in the Laboratory of Industrial Microbiology “PlantaPlus” (Tomsk, Russian Federation); control (K) experiment – clear water. Structural analysis (10 plants for each option) was carried out in late flowering (July) and in the phase of bean filling (August). Harvesting was in the 3rd decade of September with the Hege 125 combine. Biochemical parameters of seeds were determined in the Laboratory of pPlant Genetics, Physiology and Biochemistry at the Omsk ASC: nitrogen content – by automatic analyzer “KjeltekAuto 1030 Analyzer”, nitrogen to protein conversion factor for soybean grain – 6,25; the content of crude fat is by the Soxhlet extractor. It was established that soybean varieties differ in the strength of response to the use of biological products, which are mainly effective. The Cheremshanka variety has the highest weight of plants and nitrogen-fixing nodules and seed yield in comparison with the Zolotistaya variety. The maximum experimental values (on average over 2 years) without loss of seed quality were obtained in the Cheremshanka cultivar variant The experiments were performed in 2017-2018 in the fields of the Omsk Agrarian Scientific Center (Omsk, Russian Federation), with winter cereals as fore corp.
