Abstract: 
To evaluate the effects of N fertilizer rates and application time on yield components of rapeseed a study was conducted in a factorial base randomized complete block design with three replications during growing season of 2003 at research station of Gilan University. Four N fertilizer rates (0, 75, 150, 225 kg N/ha) in the form of urea and four split application times (1- 100% basal, 2-1/3 at sowing, 1/3 at 4 leaf stage, 1/3at stem elongation, 3-1/2 at 4 leaf stage and 1/2 at stem elongation, 4- 1/3 at 4 leaf stage, 2/3 at stem elongation) considered as experimental treatments. Result showed that N fertilizer increment, increased plant height, number of pod/plant, number of branches, number of grain/pod, dry matter production, harvest index, grain yield and oil production yield significantly (p<0/05), but had no effect on 1000-grain weight and pod length. N fertilizer increment reduced oil percent (p>0/05). N application time (1/3-1/3- 1/3) increased plant height, number of branches, and of pod/plant, pod length, number of grains/pod, grain yield and dray matter production significantly (p<0/05). N split application had no distinct effects on 1000 grain weight and oil percent. The effects of N application on harvest index and oil production yield was not significant (p>0/05). It is concluded that the maximum grain yield (1941 kg/ha) was achieved by using 225 kgN/ha and1/3-1/3-1/3 on application schedule.
