[Effectiveness of bacterization of soy plants by active races of nodule bacteria].
Spontaneous nodule bacteria of soybean plants are absent from the Sutn-Eastern Kazakhstan soils. Therefore, bacterization of soybean plants with these bacteria is necessary for obtaining high crops of this culture. Among tested strains of soybean nodule bacteria, strain 623(a) was found to be the most effective one. The use of nitrogen with this strain stimulated the intensive formation of nodules, the growth and development of plants, the activation of physiological processes in them, and increased the yield of green mass, hay and grains as well as the content of protein in them and its yield per area unit. Mineral nitrogen added to soil at a concentration of 120 kg per hectare decreased the activity of symbiotic nitrogen fixation, increased the crop of green mass and hay, but decreased the yield of grain of soybean and other cultures sown after it in crop rotation.
