POSSIBILITY OF APPLICATION PULSATING ELECTROMAGNETIC FIELD IN A SAFER SOYBEAN PRODUCTION

The application of methods in the field of biophysics, such as the pulsating electromagnetic field (PEMP) to biological organisms, many studies are performed that indicate specific changes and efficient action on various biochemical processes of cells in plants. The obtained results do not depend only on the plant species, but also on the climatic conditions, agrotechnical measures and exposure time, intensity and nature of the fields used in the research. The aim of the study was the effect of stimulation of soybean seeds with PEMP. Soybean seeds are rich in quality proteins, oils and fats. The three-year research period 2013-2015 implied different agrometeorological conditions. Soybean seeds of the Valjevka variety were used. Soybeans were grown with different amounts of organic granular poultry manure (control – no fertilization, 750 kg.ha-1 i 1300 kg.ha-1). Seed stimulation was performed before sowing with PEMP low frequency 15 Hz and exposure of 30 minutes. Seed stimulation efficiency was very pronounced because it statistically significantly (p <0.01) increased grain yield by 4.85% and protein content in grain by 3.52%.
