Agric., Giza, Egypt (30"01'14.6"N 31"12'41.1"E) during two successive winter seasons of 2013/2014 and 2014/2015 to study the effect of mineral nitrogen, bio-fertilization and Zn individually and together on yield and yield component of canola (Brassica napus L.) c. v. Serw 4. The experiments were conducted in split-split plot designs with three replicates. Treatments consisted of three levels of mineral nitrogen (50, 75, and 100% of its recommended dose (RD) i.e. 30kg N/fed), two levels of bio-fertilizer treatments (without and with inoculation) containing mixture of Azotobacter and Azospirillum and two levels of elemental zinc (0 and 0.3gZn/L). The results indicated that there are a significant increases in height of plant, number of pods/plant, pods weight/plant, seeds weight/plant, 1000-seed weight, seed yield, protein content, protein and oil yield. As a result of mineral N application, plots that received highest dose of N (30kgN/fed.) obtained maximum height of plant, number of pods/plant, 1 000-seed weight and seed yield. Protein content of 26. 14% and 18.98 % •were detected at high and low N rates, respectively. Under high N rate, the lowest oil content (41.31%) was observed. In contrast, highest oil contents were found for lowest N rate plots (44.28%). Inoculation of canola seed by N2-fixing bacteria (Azotobacter and Azospirillum ) significantly increased yield and its components compared with the uninoculated treatments. Zinc treatments increased all the tested growth parameters as compared to control plants. Results emphasize that N fertilization rates 75or100% of RD, bio-fertilization and Zn significantly influenced on the productivity of oil seeds rape and their interactions. So, it is suggested to use a combination of inorganic fertilizer and bio-fertilization to achieve the highest yield without a negative effect on seed quality that will lead to sustainable environment.
