EFFECTS OF THE ACOUSTIC RADIATIONS ON THE INTENSIFICATION OF PLANTS GROWTH

Abstract The results of investigations of influence of acoustic radiation in the frequency range of 20 Hz and 50 kHz of some physical and chemical properties of irrigation water are represented. It is shown that range of ultrasonic radiation in a range close to 20 kHz is more effective for productive drip irrigation experienced plants which leads to increasing the concentration of dissolved trace metals in the irrigation water and also affects the change of pH suitable irrigation water. Two fixed frequencies in the studies were chosen to more clearly establish the fact of the occurrence of ultrasonic cavitation in irrigation water and were determined by the capabilities of the created device. The frequency of 20 kHz was chosen as the preferred one for fixing the increase in tomato yield by periodically weighing it and comparing it with the control irrigation line. Tomatoes were chosen as the most common greenhouse crop and a product often used in the diet.
