Efficiency of using biological products in the production of organic soy seeds

Abstract

The results of studies of the effectiveness of biological products under the organic seed material production of soybean varieties of domestic and foreign breeding (Suzirya and Kent) are presented. The biological products from leading manufacturers of Ukraine have been used. During 2016–2018 in Right-Bank Forest-Steppe of Ukraine at the Skvyra organic demonstration site of the Skvyra Experimental Station of Organic Production of the Institute of Agroecology and Environmental Management NAAS investigated the effects of biological products on the quality and quantity of soybean organic seeds: weight, similarity, germination energy, phytosanitary condition of crops and yield of 1000 seeds. The soil of the experimental field is small humus chornozem (black soil). The research techniques are generally accepted. It was established that the processing of experimental plots with various complexes of biological products provided an improvement in the quality indicators of seeds of both varieties: the mass of 1000 seeds has increased by 2.4–4.5%; the similarity and seed germination have increased by 3.4–9.8% and 3.8–5.0%. The use of biological preparations has contributed to a significant decrease in the weed infestation of soybean compared with the increased competitiveness of cultivated plants relative to segetal ones. It has been proved that complexes of biological preparations stimulated the growth and development of soybean plants and contributed to the accumulation of plant nutrients in the soil. It was noted that favorable weather conditions increased the effect of biological agents and increased their effectiveness in forming high-quality organic soybean seeds harvest. It is proved that the cultivation of soybean according to organic technology requires the use of biological products for pre-sowing treatment of soil and seeds, as well as in the process of growth and development of culture.
