We made the foliar fertilization experiments in the near of Szarvas in 2022 in cooperation with Hed-Land Hungária Ltd. The soil of the experimental area is deep carbonate chernozem meadow soil. The main characteristics of the soil of the experiment: its physical type is clay loam, its chemistry is acidic or weakly acidic, the cultivated layer does not contain CaCO3, based on the humus content, the N-supply of the soil is medium. In the experiment, 5 foliar fertilizer and amino acid treatments were examined, supplemented by an untreated control plot. The treatments had a positive effect on maize yields in the experiment. The achieved average yields increased by 7.80 – 25.61% the average yield of the control, untreated plots (7.56 – 9.37 t/ha). The average yield achieved in the treated plots reached the limit of the statistically difference, so the effect of the treatments was significant. The highest yield average was obtained in the 2x Aminocore 2 l/ha and Ionic Zn 0.2 l/ha treatments (9.37 t/ha). During the experiment, we also examined the changes in the quality of the maize grain. Protein%, starch%, and oil% were measured in the study. We were able to establish that no clear correlation could be established between the treatments and the quality parameters. The values measured in the untreated control plots sometimes improved and increased in the treated plots, while in other cases we could see a slight decrease. Amino acid preparations therefore have a significant effect on the average yield, the quality is more of a genetically determined property.
