| Abstract | ||
| Experiment was carried out at the experimental farm of the College of Agriculture – University of Baghdad – Abu Ghraib during the autumn season of 2001-2002. The main objective was to find out the effect of nitrogen levels (0, 220, 240 and 260 kg N.ha-1 on yield and yield components of four rapeseed genotypes (Bristol, RPC 1991, Pactol and RpGp 902). The layout of the experiment was a spilt-plot in a RCBD with four replications. The genotypes considered main plots whereas nitrogen levels considered the sub-plots treats. The traits studied were plant height, days from planting to 50 % flowering, days from planting to full maturity stage, number of fruit branches per plant, area of pods, number of pods per plant, number of seeds per pod, 1000 seeds weight, dry weight, seed yield, percentage of oil and protein in seeds. | ||
