Possibility of nitrogen fixation in Pisum sativum and triticum aestivum

In order to achieve an accumulation of larger quantities of organic matter in the soil after the growing of peas, the influence of inoculation with azotobacter, nitragine and their mixture, without or combined with nitrogen fertilizer (80 kg N/ha as KAN) on some indicators of peas productivity was investigated. At the same time, some productive characteristics of the wheat cultivar Srbijanka, which features an ability to bind nitrogen from the atmosphere due to the presence of diazotrophs in its rhizosphere, were investigated
