In field conditions, the germination rate of Dilbar variety sunflower seeds was studied under different application rates of biostimulants: when Fitovak 20% was applied at 0.6+0.7+0.8 ml/l/ha, the number of emerged seedlings amounted to 54,857.1 units; with Biodux at 3.0+4.0+5.0 ml/l/ha – 54,457.1 units; and with MERS at 4.0+0.3+0.5 ml/l/ha – 55,085.7 units. It was observed that the highest number of emerged seedlings, 55,085.7 units, with a germination rate of 96.4%, occurred when the MERS biostimulant was applied at 4.1+0.3+0.5 ml/l/ha.
