Purpose. To study the influence of organic fertilizers produced by advanced technologies on plant growth and development and formation of soybean crop yields in the conditions of the Western Forest-Steppe. Methods. Field experiments winh the variety Ustia were carried out during 2013–2016 at the research field of the State Agrarian and Engineering University in Podillia. Organic fertilizers “Bioproferm” and “Bioactive” and mineral fertilizer (N120P80K80) were applied during the basic soil cultivation, liquid organic fertilizer “Biokhrom” was sprayed during soybean vegetation in the phase of budding. Soybean farming practices was convential for the conditions of the Western Forest-Steppe of Ukraine. Attendant studies and observations were performed according to common techniques. Results. In all variants of applying organic fertilizers “Bioactive” and “Bioproferm” the agrophysical and agrochemical parameters of soil were being increased, biological processes were activated thus resulted in improvement of soil nutritional and water regime. This contributed to increase plant density in the phase of emergence and at the harvesting period because field germinating ratio and plant survival were higher than in the control by 6.7–7.1 % and 4.4–4.6 %, respectively. In these variants significantly more leaf surface area was formed as compared with the control. The most leaf area of soybean plants at the beginning of flowering phase (31,200 m2/ha) and at the end of flowering (41,600 m2/ha) was formed in the variant when the organic fertilizer “Bioproferm” (10 t/ha) with balanced Cr+3 content was applied during the basic soil cultivation, and soybean crops in the phase of budding were sprayed with growth regulating liquid organic fertilizer “Biokhrom” (5 l/ha). In averaged over 4 years, the highest soybean grain yield (3.06 t/ha) being 1.25 t/ha more than control has been obtained when introducing organic fertilizer “Bioproferm” at autumn ploughing and foliar feeding with growth regulator “Biokhrom”. Conclusions. The use of organic fertilizer “Bioproferm” (10 t/ha) and liquid organic fertilizer with growth regulating properties “Biokhrom” (5 l/ha) positively influenced on the growth and development of soybean plants of the variety Ustia during the entire cropping season and in the years of the research (2013–2016) had provided crop yield increase by 62.4–69.1 % as compared to the control as well as production of environmentally sound grain with the sufficient content of trivalent chromium.
