Chemical Composition of Maize Grain (Zea mays L.) in Relation to the Depth of Fertilizer Application

The artide presents the results of a 2-year field study aimed at assessing the chemical composition of maize plants depending on the depth of two-component (Nl') mineral fertilizer placement in the soil profile, the type of nilrogen ferlilizer and the date of its application. Weather conditions, mainly thermal, in the early maize growing season, had no signitcant etfect on the chemical composition of maize grain. The research showed the noticeable highesl content of crude fiber in maize grain as a result of broadcast application of the fertilizer (0 cm), while the lowest for row fertilization at depths of 5 cm and 15 cm. The application of urea in maize cultivation and the pre-sowing application of nitrogen significantly increased the starch content in maize grain compared to ammonium nitrate and the top dressing application of nitrogen fertilizer.
