A field experiment was conducted with three maize hybrids: DKC4416, LG 31.390 and Premeo under irrigated and nonirrigated
conditions. The experiment was carried out during the period 2022-2024 at the Academic Technological Complex (ATC) of Trakia University, Stara Zagora, Bulgaria. The productivity of the green mass of the three maize hybrids was determined. After foliar fertilization with a complex of fertilizers Aminosol, Lebosol B, Lebosol Zn and Nutriplant 36, an increase of 22.8% (for LG 31.390), 24.4% (for DKC 4416) and 31.8% (for Premeo) was determined, on average for the three-year study period. The parameters of the additional yield of green mass have been calculated. Optimization of nutrients and irrigation regime contributes to increasing the values of additional yield by 276.8% (Premeo) to 353.5% (DKC 4416). An increase was also reported after applying the organic fertilizer Kinsidro Grow and the nitrogen stimulator N-Lock of 338.3% in DKC 4416, 318.6% in LG 31.390 and 276.8% in Premeo. The efficiency coefficient of irrigation water use has been established. The highest values were recorded for variant 3 with the highest coefficient calculated for DKC 4416 (40.0).
