Abstract: The factors of fertilizer（A） and density（B） were designed with five levels in this experiment. The results indicated that fertilizer and density had obvious effects on the agronomic characteristics and yield of Shuangyu 919. When the fertilizer was 337.5 kgN/hm2 and the density was 60 000 plants/hm2，the agronomic characteristics were the best and the yield was the highest（14 843.20 kg/hm2）.

Key words: maize（Zea mays L.）, Shuangyu 919, fertilizer level, planting density, yield
