The study was carried out to study effect of tiller removing or remaining on yield and yield components ofmaize under different fertilization amount using‘Xianyu 335’in the eastern humid region of Jilin Province as mate-rials. The results showed that tiller removing or remaining was not main factor influencing the yield at harvest, andremained tiller could simplify the cultural practice,which could cut down cost and raise the outcome. The ratio ofNPK fertilizer was the major factor which affected the yield and yield components among each treatment. Fertiliz-er proportion had bigger impact on yield and yield components with tiller removing or remaining. The rational fertil-ization of NPK tended to increase plant growth and harvest yield of maize.
