Clarica) was examined on chernozem soil under irrigated and non-irrigated conditions in a field experiment. The following results were made: • the element concentrations in the plant decreased over time, • there is no difference between the dynamics of nutrients on irrigated and non-irrigated sites because rainfall was satisfactory for plants in vegetation period, • the N doses not only significantly increase the nitrogen content in maize, but also have a noticable effect on Ca and Mg concentrations, • because of the acidifying effect of N-fertilizers, increasing the amount of N-fertilizer increased the Mn, Zn, Cu content of the plants, • the P doses have a significant effect on the maize P and N content and the Zn concentration of the plant via P-Zn antagonism in the soil, • as the high K doses treatments alter the ion ratios in the soil, the Ca, Mg content of the plant decreased.application/pdffolyóiratcikkOpen Accesshttps://doi.org/10.34101/actaagrar/1/3515Acta Agraria Debreceniensis1Acta agrar.
