The methods of increasing productivity of sunflower hybrids using fertilizers and a micronutrient mixture Agromineral in the forest-steppe of the Middle Volga were described. The results of 2017–2018 studies are presented. The leaf area, the photosynthetic potential, the crop structure and the yield at different doses of fertilizers were assessed. The maximum value of the photosynthetic potential is formed by crops of the mid-season hybrid 8H477KLDM (4.386 million m2/ha per day). The use of fertilizers and micronutrient mixtures increases the photosynthetic potential and productivity by 9.09 ... 9.36 c/ha with an absolute value of 29.46 ... 31.83 c/ha.
