Abstract
Objective. To study the effect of combined preparations based on highly active strains of Brad-yrhizobium japonicum and complexes of carboxylates of trace elements germanium, molybdenum, and ferrum on a symbiotic apparatus of soybean plants, in order to increase the efficiency of bacte-rial inoculants. Methods. Gas chromatography, microbiological, physiological. Results. The com-bination of a microbiological preparation based on efficient strains of nodule bacteria with complexes of nanoparticles of carboxylates Mo, Fe, Ge was found to promote the enhancement of nodulation activity, provide growth of mass of root nodules, activate the nitrogen-fixing activity of symbiotic soybean systems. When use the preparation combined with germanium and molyb-denum compounds, nitrogenase activity increases by 23–63 %, in combination with inoculum with germanium and ferrum nanocarboxylates — by 14–21 % depending on the phases of soybean or-ganogenesis. The complex application of biological and abiotic factors influencing the formation and functioning of symbiotic nitrogen-fixing systems contributes to the improvement of plant mor-phometric parameters and provides high yields of this crop. At the same time, it was established that germanium carboxylate complexes with molybdenum carboxylate, as well as germanium nanocarboxylates, should be used as effective stimulants for the formation of seed productivity of soybean plants and nitrogen-fixing activity of symbiotic systems created with their participation. In the experiment, soybean yield under the combination of B. japonicum with germanium and molyb-denum nanocarboxylates increased by 10 %, and by 13 % — under the complex application of bac-terial inoculum with germanium and ferrum carboxylate nanoparticles. Conclusion. Application of these complexes of nanocomponents in microbiological production technologies will allow plants to be supplied with additional nutritional elements, forming effective plant-microbial systems and ob-taining high and stable crops of environmentally safe food and feed protein.
