Abstract
The paper highlights the effect of inoculation by means of biological specimens on formation of photosynthetic parameters, nodule-forming capacities and yield of pea grain. The authors reveal the varieties which mostly respond to the tillage, effective specimens and methods of their application. The researchers explored two varieties of pea as Omskiy 9 and Omskiy 18 and two biological specimens (risotorphine and ruminatine). The study was conducted in the experimental fields of Omsk agricultural research center in 2016-2017 in the following variants: control (without inoculation), inoculation by means of risotorphine, inoculation by ruminatine and combined tillage. The researchers observed different meteorological conditions during the research. The experiments and calculations of the experimental data were carried out by means of general methodics. The positive effect of inoculation on increasing of such parameters as leaf surface index and photosynthetic potential is observed. Active symbiotic potential, number and weight of nodules rhizosphere of pea had a maximum value when being treated by biospecimen ruminatine and combined inoculation of seeds by risotorphine and ruminatine. The authors highlight significant positive relationship between photosynthetic and active symbiotic potential. Inoculation influenced the yield of pea varieties in a different way in the years of research. The results of variance analysis showed that conditions of experiment influenced the yield of varieties – 34.4 %, the proportion of inoculation effect was 25.0 % and genotype – 17,3 %. Omsk 18 variety was characterized by the highest rates of photosynthetic and symbiotic activity. Seed treatment with ruminatine and combined inoculation with risotorphine and ruminatine have impact when growing pea in the conditions of southern forest-steppe of Western Siberia.
