The aim of the research is to study the effect of hydroponic solution processing with an acoustic-magnetic field effect to the cucumber yield. The scientific hypothesis expresses the possibility of influencing the vegetative processes of cucumber growth by means of physical fields to the hydroponic solution used in growing crops. The research was conducted using an empirical method. Observations of plant growth were made by internode distances of the cucumber liana measuring at the experimental and control plots. The hydroponic solution used for growing agricultural crops was treated with an acoustic-magnetic field created by an acoustic-magnetic device at the experimental plot. The hydroponic solution was not treated at the control plot. The method of paired comparison of each plot yields has fairly accurate results. Various modes of the acoustic-magnetic device operation were considered using experiment planning at three levels of significant factors: voltage, frequency, and device working zone length for comparison. The cucumber liana internode distance is taken as the resulting indicator. The model is based on regression analysis. According to the study results, it was found that internode distance increasing leads to yield increasing, and cucumber yield is related to the mode of operation of the acoustic-magnetic device, the supplied voltage frequency and the size of the device. It is possible to design devices which operation parameters create a resulting indicator acceptable value. This fact proves the efficiency of calculating parameters methods used for design of acoustic-magnetic devices.
