ABSTRACT
On the basis of a 4–year study, the effect of fertilization methods on the uptake and accumulation of mineral components by maize was evaluated. Two methods were used: by broadcasting over the whole surface and by band fertilization. The applied fertilizer level was gradually increased from 17.4 to 56.7 kg P ha-1 with the use of superphosphate and ammonium phosphate. It was found that the uptake and accumulation of mineral components depended on all the studied factors and their effect was increasing with the advancing vegetation. Band fertilization and the use of ammonium phosphate kept increasing the accumulation of all mineral components from 4-5 to 8-9-leaf-stage, in comparison with broadcast fertilization and superphosphate application, respectively. No distinct effect of phosphorus fertilization level on the uptake and accumulation of mineral components was visible before the stage of 8-9 leaves. Regressions were calculated for the relationship between the mineral components accumulation and the lapse of time from emergence to 8-9-leaf-stage and for the relationship between the uptake of mineral components and the accumulation of dry matter.
