The article presents the results of experimental studies on the feed productivity of maize (corn) hybrids of different maturity groups depending on the influence of the plant biostimulant Regoplant and the foliar microfertilizer Plantafol against the background of N90 fertilization. The productivity of new maize hybrids Chonhar (FAO 420) and Arabat (FAO 430) was studied, with biomass harvested at the milk-wax ripeness stage. The research employed field, laboratory, and mathematical-statistical methods, and the trial design followed a factorial experiment with replication. Yield accounting was carried out with conversion to absolutely dry matter, while feed quality parameters were assessed using standardized methodologies, ensuring accurate comparison between treatments. It was established that among mid-late maturity maize hybrids, Arabat was the most productive, with a biomass yield of 68.2 t/ha, a feed unit output of 23.9 t/ha, and metabolizable energy of 253 GJ/ha. The highest productivity was achieved with foliar application of Regoplant during vegetation, reducing the energy cost per ton of digestible protein to 55.2 GJ, or by 35% compared to the N90 control. Thus, under the conditions of southern Ukraine, the use of growth regulators Regoplant and Plantafol in combination with N90 increases the silage yield of Arabat by 25–27% and Chonhar by 24–25%, corresponding to 68.2–69.6 and 65.5–66.2 t/ha, respectively. Cultivation of the Arabat hybrid with Regoplant most effectively reduced the energy cost per ton of feed units (2.2 GJ) and digestible protein (55.2 GJ) and ensured the highest energy efficiency coefficient (EEC) — 4.77. In contrast, foliar feeding with Plantafol reduced the efficiency compared to Regoplant. Combined application of Regoplant and Plantafol on Arabat and Chonhar hybrids decreased overall efficiency relative to their separate use, which is important for optimizing silage production technologies.
