Effect of additional inoculation with Rhizobium leguminosarum on vegetable pea plants

Relevance. Grain of vegetable pea varieties is processed at canning factories, frozen, dried, and consumed fresh. Industrial cultivation of peas can be made more environmentally friendly by using biological preparations that contain growth-stimulating bacteria, for example Rhizobium species. With additional inoculation with rhizobacteria, legumes have higher values of traits characterizing vegetative development, biochemical parameters and yield; their immunity and resistance to abiotic stress increases as well. Methodology. The aim of our study was to evaluate the effect of additional inoculation of Rhizobium leguminosarum strain 245a on biometric and physiological parameters and yield of vegetable pea varieties. The experiment was carried out at Krymsk Experiment Breeding Station - a branch of VIR (Krasnodar Region, Krymsk). We studied six commercial cultivar: Prima, Mayak, Alpha 2, Vesta, Parus (leafless morphotype) and Patriot. The seeds were treated the day before sowing with an aqueous solution of the biopreparation Rhizotorfin (produced by ECOS BIOPREPARATIONS, St.Petersburg) and with water in the control variant.
