The study presents the results of a 4-year field study aimed at assessing nutrient content of two maize juvenile stages (BBCH 17/18 and BBCH 18/19) in relation to the depth of two-component (NP) mineral fertilizer placement in the soil layer (0, 5, 10, 15 cm), type of nitrogen fertilizer (ammonium nitrate, urea) and date of its application (before sowing, in the BBCH 15/16 stage). Maize showed a high capacity to compensate for growth in the early developmental stages, which resulted from the action of the component placed in deeper soil layers. The highest phosphorus content in maize plants was recorded at the 8-9-leaf stage for a depth of 10 cm. The effect of nitrogen dilution depended on the form and date of fertilizer application. Plants fertilized with ammonium nitrate at the 5-6-leaf stage showed the greatest decrease in N content from the 7-8-leaf stage to the 8-9-leaf stage. The content of phosphorus and nitrogen at the 7-8- and 8-9-leaf stages was signifi-cantly correlated with grain yield. Higher correlation coefficients were recorded for the 8-9-leaf stage.
