The aim of this work was to determine the effect of fertilization method of maize with ammonium phosphate on grain yield, its components and moisture of grain. Two methods of fertilization were applied: broadcasting before sowing and band (starter) fertilization simultaneously with sowing of grains. The row application of ammonium phosphate increased significantly the yield of grain in comparison to broadcasting fertilization, independently of weather conditions and content of phosphorus in soil. The difference in grain yield of maize between the fertilization methods amounted to 3.19 dt/ha for 12 April sowing date, 2.12 dt/ha for 26 April and 2.65 for 10 May
