The effect of treatment of legume seeds with bacterial preparations on crop formation

The article presents the results of studies on the formation of the yield of leguminous crops (pea and soybean) when using pre-sowing seed treatment with bacterial preparations. The effect of bacterial preparations Azotovit, Phosphatovit, Azolen Zh on the completeness of seedlings, the duration of vegetation, crop structure, yield and quality indicators of grain was studied. The agricultural approach under study contributed to an increase in the completeness of seedlings, the safety of plants for harvesting, accelerated the germination of seeds and allowed them to start harvesting earlier. The use of bacterial preparations increased the soil microbiological activity. Pre-sowing treatment of pea seeds increased plant productivity, grain size and seed quality; it allowed to harvest more finished beans from soybean plants and also increased the weight of seeds from one plant. The studied bacterial preparations contributed to a significant increase in yield compared to the control in both crops, increased the content of crude protein and crude fat in the grain. For pea, the maximum yield was provided by Azolen Zh, for soybeans – Phosphatovit. Pre-sowing treatment of leguminous seeds with bacterial preparations is an effective means of increasing grain yield and quality on light gray forest soils.
