For the successful application of festulolium in a new region, in particular in the forest-steppe of the Penza region, one of the main tasks is to create a sustainable seed production system based on energy and resource saving. Therefore, the aim of the current research was to examine the aftereffect of pre-sowing treatment of festulolium seeds with complex microelement fertilizers and biological preparations on seed productivity. The research was carried out in 2019-2021 at the experimental site of Penza State Agrarian University (Penza, Ryussia). The aftereffect of the use of micro- and biofertilizers (Azosol-36, Extra, Megamix-Profi, Siliplant, Zircon, Agrika, Agrika + microelements, Agat-25 Super) was observed during the treatment of seeds with festulolium varieties VIK-90 and Izumrudny on indicators of photosynthetic activity of agrocenosis and the formation seed production in the second growth year. As a result of the research, it was found that the examined growth regulators had a positive effect on the formation of leaf area, photosynthetic potential and net productivity of photosynthesis. When used for seed treatment the Izumrudny variety of bacterial preparation Agrika + microelements the maximum quantity of generative sprouts was noted - 712 pcs/m2, the greatest length of inflorescences - 23.5 cm, the number of spikelets in the inflorescence - 41.0 pcs., the number of seeds in the inflorescence - 79.0 pcs and weight of 1000 seeds - 3.27 g. Seed productivity was 845 kg/ha, which is 24.9% higher than the control.
