Abstract: The field experiment on ef fect of dif ferent nitrogen applicat ion on y ield, nit rogen distr-ibution and utilizat ion in water wheat under water stress has been processed in Hebei province where is serious dry area from 1997 to 1998. The results show that with the increase of N application, nitrogen utilization efficiency decreased, the treatment ( 225 kg/ha) arrived the highest y ield,and the yield of other treatments applied over the rate decreased. With the increase of N application, N absorbed was mainly distributed in nutrition orgens of plant s in which leaf had the biggestratio. At the same time the harvest index declined in turn.

Key words: Water stress, Fertilizer, Yield, Nitrogen utilizat ion
