In the conditions of the forest-steppe of the Middle Volga Region, the research was carried out on the crops of maize hybrids with fertilizer application for planned yields of 7.0 and 9.0 t/ha and systemic treatment during vegetation with preparations of Megamix. In 2020-2022, studies were conducted at the "Samara State Agrarian University", where it was found that maize hybrids form a photosynthetic potential of 2,670.3 to 3,091.2 thousand m2/ha days. With the application of fertilizers for the planned yield of 9.0 t/ha and the complex application of Megamix preparations, the maximum value of photosynthetic potential is reached by the crops of the hybrid Amarok with the indicator of 3,091.2 thousand m2/ha, and the maximum increase is 112.4 thousand m2/ha days in the crops of the hybrid Si Telias. The average yields of the maize hybrids in the three years were in the range of 5.10 - 8.36 t/ha, with the maximum yield achieved in crops of the hybrid Amarok when fertilizers were applied for the planned yield of 9.0 t/ha and systemic application of stimulating preparations of Megamix. The best efficiency of application of stimulating preparations is observed against the background of fertilizer application for the planned yield of 7.0 t/ha. The increase was 0.18-0.72 t/ha, while on the second background (fertilizer application for the planned yield of 9.0 t/ha) the increase was 0.18-0.50 t/ha.
