The main objective of this study was to reveal the growth and yield of waxy corn in different nitrogen fertilizer and density in seasonal arid region.Field experiments were conducted at jinxian country，Jiangxi province.Yield and yield components were determined and air temperature and rainfall were monitored.The results showed that drought was occurred in September，October and November in 2011.Fresh fruit spike production was increased gradually with increasing amount of density and nitrogen.Fresh fruit in 225 kg/hm2 nitrogen fertilizer and 60 000 plants/ha was highest in all treatments.It was increased by 3229% than none nitrogen treatment.Nitrogen agriculture efficiency of 175 kg/hm2 nitrogen with 52 500 plants/ha and 175 kg/ha nitrogen with 60 000 plants/ha were 1057 kg/kg and 1179 kg/kg，respectively.They were higher significantly than others.Nitrogen agriculture efficiency of 275 kg/hm2 nitrogen with 4 500 plants/ha was 376 kg/kg，and it was the lowest.
