Abstract
In crop production, the usage of various microelements for seed treatment is of great importance, which have a stimulating effect on the growth and development of plants. This article presents the results of the effect of presowing treatment of soybean seeds with agrominerals based on tagan bentonite and fungicidal biostimulants. The agrominerals consist of complexes of succinic acid and ethylenediamine succinic acid with silver or copper ions in combination with a film-forming substance, as a starch, to increase economically useful qualities of the crop. Various effects of agrominerals were revealed, on the growing season of soybean, such as development, yield, weight of 1000 seeds, quantity of beans on plants, protein and fat content in seeds. It has been established that pre-sowing treatment with separate complexes ofSA-Сu, SA-Ag, and Starch-SA-Cu leads to a reduction in the vegetation period by 5-8 days. However, agromineral based onTgn-EDSA-Ag-Starch and Tgn-EDSA-Cu- Starchon the contrary, increases the duration of the vegetation period by 4-7 days. The yield increases of (Nur+) 3.1-3.5 centner/hectar (cwt/ha) and (Progress) 3.0-4.1 cwt/ha in comparison with the control.Also, the influence of agrominerals on the weight of 1000 seeds, the number of beans on plants, the content of protein and fat in seeds were noted.
