The essence of the dual-frequency method is the selection of biologically active frequency, which tends to change in a narrow range and simultaneous processing of seeds to several biologically active frequencies. Results of laboratory and field studies in Tat NIISH show the positive impact of two-frequency method and a more effective stimulant effect.
