Results of Application of Biostimulant Grow-B Based on Triterpene Acids in Tobacco Cultivation

Application of Grow-B biostimulant for pre-sowing soaking of tobacco seeds in concentration of 0.05% during six hours increases the weight of tobacco seedlings by 43%. Sowing of treated tobacco seeds in a greenhouse together with double treatment of seedlings with aqueous solution (1 l/m2 ) of Grow-B preparation in concentration of 0.05% increases seedling length by 24%, stem diameter by 30%, weight of above-ground part by 96%, root system by 95%, yield of standard seedlings by 29%. The prolonged effect of quality seedlings obtained under the action of biostimulant in the field period manifested itself by increasing the yield of tobacco and quality of tobacco raw material.
