The research was carried out on the experimental fi eld of the Northwestern Dairy Farming andGrassland Management Research Institute on the drained sod-podzolic medium-loamy soil.The crops such as barley – variety “Vybor” and peas – fi eld variety“SZM-85” included in theregister of the Vologda Oblast were used in the fi eld test. They were grown in single-crop sowingand mixed crop sowing with a ratio of components in the mixture of 60:40% from the seedingrate in its pure form. The scheme of the test included 21 variant, the area of the test plot was5.8 m2, 4-fold tier. Placement of variants was systematic. Records and observations were carriedout by according to the technique developed at the All-Russian Williams Fodder ResearchInstitute and the “Evaluation of microbial preparations effi ciency in agriculture”. The aim of theresearch was to study the effect of fertilizers and biological products on the yield and quality ofbarley and peas in single-crop and mixed crop sowing during harvesting for grain purposes. Toachieve this goal, the following tasks were solved: to assess the impact of fertilizers and biologicalproducts on the yield of barley and peas in single-crop and mixed crop sowing; to determinethe impact of fertilizers and biological products on the quality of barley and peas; to study theinfl uence of mineral fertilizers and biologicals on plant height and weight of 1,000 seeds ofbarley and peas. As a result of the research, it was established that the biological product ofassociative diazotrophs Flavobacterium increases the yield of barley grain with or without theapplication of fertilizers. The use of fungus arbuscular mycorrhizae provides an increase in theyield of a single-crop sowing of peas. In the mixed sowing of barley and peas, the yield of grainincreases with inoculation of seeds with nitrogen-fi xing and phosphate-mobilizing preparations.The growth of grain yield due to application of biological products is caused by changesin the structure of elements that determine the grain productivity of crops. In mixed sowingwith peas, favorable conditions are created for the nitrogen nutrition of barley; as a result, evenwithout the introduction of nitrogen fertilizer, the same amount of raw protein accumulatesin the grain as when applying N30. The AM preparation has a positive effect on plants in bothsingle-crop sowing of peas and the sowing of peas mixed with barley. The use of biologicalproducts and fertilizers in full dose (N30P30K45) in the cultivation of annual crops provides anincrease in grain yields by 20–36% and allows for obtaining forage with a high content of crude protein in barley grain to 20.3% and in peas – to 28.3%
