To determine the effect of seeding rate and nitrogen fertilizer on seed yield and its components for oilseed rape a field experiment was carried-out in Agricultural Research Station of Islamabad-e-Gharb in two cropping seasons (2007-08 and 2008-09). A factorial arrangement using randomized complete block design with 4 replications was used. Experimential factors were seeding rate at 4 levels 4, 6, 8 and 10 kg ha-1 and five nitrogen fertilizer rates 0, 30, 60, 90 and 120 kg ha-1 from urea source. Results showed that seed yield was affected by increasing seeding rate as the seed yield in highest and lowest seeding rates were 5391 and 4041 kg ha-1, respectively. Increasing seeding rate reduced branch plant-1 and pod plant-1, but increased plant height. Results also showed that increasing nitrogen increased seed yield as the highest level of nitrogen had the highest seed yield with 5392 kg ha-1 and the lowest seed yield with 4257 kg ha-1 belonged to the lowest nitrogen level. Seed yield, 1000 seed weight, plant height and pod plant-1 increased as application of nitrogen fertilizer increased.
