Abstract
The article indicates that in the agro-industrial complex of Northern Kazakhstan, much attention is paid to the issues of progressive improvement of soil fertility, crop yields, increased production of grain, feed, and other crops based on a scientifically based farming system. Currently, there is a particular problem of providing the population with high-protein food products, which in the grain zone should be carried out in the system of field crop rotations. The introduction of soybeans into various types of field crop rotations contributes not only to the accumulation of atmospheric nitrogen, but also to the improvement of the agrophysical, biological and agrochemical properties of ordinary chernozem. In addition, soy grain contains a large amount of balanced and easily digestible protein, vegetable oil, a variety of sugars and carbohydrates, as well as essential vitamins and trace elements necessary in the diet. Field studies were conducted to identify the effectiveness of the use of biological preparations on soybean crops and their effect on the formation of nodule bacteria, the formation of the size and quality of the soybean harvest, to identify the most effective of them in the conditions in the Northern region of Kazakhstan. The use of bacterial preparations had a positive effect on the density of soybean plant coenosis, namely on field germination, on the dynamics of plant growth, on the accumulation of raw and dry mass of soybean plants. All the studied bacterial preparations reduced the spread of fungal diseases in this culture. The use of bacterial preparations has increased the yield and profitability of soybean cultivation.
