The liquid-phase biological product (LBP) is a high-level biogenesity, nutritional value and physiological effect. This work considers an efficacythe LBP influence on thegrowth and development of potatoes. The research was conducted of a VNIIMZ test field (Tver Region, Russia). The LBP was used for potatoes flooding and spraying in various concentrations on the background of the basic organic fertilization. It has been revealed that the spraying was more effective. The maximum crop rise (14.9% relative to the basic organic fertilizer background) was achieved by a triple spraying with the LBP working solution made by its dilution 1: 300 by water. The LBP promoted the development of medium and large potato tubers-which finally formed almost 90% of the total productivity. This fact was caused by greater forming of new tubers: the number of them grew by 54% during the test period.
