abstract:
The aim of the research, conducted in the years 2000-2003, was to examine the effect of maize fertilization method on the initial growth of maize. Two methods of fertilization were applied: broadcasting and in rows simultaneously with sowing. The effectiveness of the fertilization methods was studied in three sowing terms and on three maize varieties of different earliness. The row application of ammonium phosphate increased the dry mass of one plant as well as the yield of dry mass of plants in the phase of 4-5 leaves, in comparison to broadcast fertilization. The starting fertilization increased the dry mass of one plant and the yield of dry mass in the phase of 4-5 leaves, in all the terms of sowing. Dry mass of one plant and yield of dry mass in the phase of 4-5 leaves increased with delay of term of sowing from 12th April till 10th May.
