Three maize inbred lines (Os86-39, Os89-35 and Os87-24) were grown in pots with Eutric Cambisol using 9 fertilisation variants (control 10 kg/ha Zn - on soil surface; 5 kg/ha - foliar application; 61 kg/ha P; 61 kg/ha P and 10 kg/ha Zn - on soil surface; 61 kg/ha P and 5 kg/ha Zn - foliar application; 183 kg/ha P; 183 kg/ha P and 10 kg/ha Zn - on soil surface; 183 kg/ha P and 5 kg/ha Zn - foliar application). The effects of P and Zn fertilization on the dry matter yield, plant height, stalk diameter as well as P and Zn concentrations in ear-leaves were investigated. Significant differences were found between the lines in all parameters investigated except for P concentration. The line Os87-24 was characterised by the best results in the total biomass production. Zn fertilization decreased while P fertilization increased total plant dry matter mass. P fertilization increased its concentration in the ear-leaves. Zn fertilization, especially foliar, resulted in Zn concentration increase in the ear-leaves of the lines investigated.
