Abstract: In order to investigate the effect of nitrogen rate and plant density on agronomic characteristics and yield of canola an experiment was carried out at the Iran Rice Research Institute in 2006 to 2007. The experiment was laid out as a split plot, Randomized Block Design with three replications. Main factor was nitrogen in four levels (0, 46, 92 and 138 kg N m-2) and sub factor was plant density in three levels (65, 85 and 95 plant m-2). Results showed that nitrogen had significant effect on plant height, minor stem number, stem diameter, pod length, grain number per pod, biologic yield and grain yield. The most and least grain yield were produced in 138 and 0 kg N ha-1 treatments, respectively. Plant density had significant effect on minor stem number, stem diameter, pod number per plant, pod length and grain yield. The most grain yield were produced in 80 plant m-2 plant density. According to results apply 138 kg N ha-1 and 80 plant m-2 plant density for the best plant attributes were recommended.
