Abstract：Effects of N fertilizer combined with new synergist on summer corn growth index,yield and yield components,economic benefits and N fertilizer efficiency were studied by field experiment.The results showed that combined application of N fertilizer and new synergist could significantly improve stem diameter, ear leaf area,cob length of summer corn,increase kernels per row and 1 000 -grain weight,and improve AEN and PFPN.It also could save cost and improve economic benefit with N fertilizer application amount de-creasing by 60 kg/hm2 and income increasing by 346 yuan /hm2 .The new synergist (N -server)was better than traditional synergist (DCD),and higher dosage was better than lower one on summer corn growth and yield.Under the condition of this field trial,the optimal application amount of new synergist (N -server)was 5.1 30 L/hm2 .
