Abstract. This study was conducted at the Agricultural Research
Station, Hada El-Sham, King Abdulaziz University during 2006 and
2007 seasons. Four canola varieties, Callypso, Pactole, Sero-4 and
Sero-6 varieties were tested under four nitrogen fertilizer rates (0.00,
92,138 and 184 kg N/ha) to determine the effect of nitrogen fertilizer
on the canola (Brassica napus L.) seed yield, yield components and
seed quality. The results showed that as nitrogen fertilizer rate
increased, plant height, number of fruit / plant, 1000-seed weights,
seed weight / plant and protein content increased. However oil
content (%), was the highest under 92 kg nitrogen rate, then
significantly decreased under the higher nitrogen rates. In terms of
variety differences, the plant height data revealed that Sero-4 was the
taller, followed by Sero-6, and then Callypso and Pactole varieties and
Pactale and Sero-6 varieties produced the highest number of
fruits/ plant and significantly dominated over the Sero-4 and Callypso
variety. In addition, Pactale and Sero-4 had the highest 1000-seed
weights without significant differences between them, while Callypso
variety was the lowest. Pactole variety was also the highest in seed
weight / plant, while Sero-4 and Sero-6 varieties were not significantly
different in seed weight / plant. Pactole variety was the highest in
protein content followed with a significant difference by Sero-4, then
Sero-6, while the lowest variety in protein content was Callypso
variety. The rate of 138 kg N / ha produced the highest seed yield / ha
(1550.51 kg), protein content (28%) and had 34.10% oil content. Oil
content of the studied varieties ranged from 37.80% for Callypso
variety to 32.04% for Sero-4 variety, and the statistical comparisons
showed significant differences among the four studied varieties.
Furthermore, iodine value and refractive index of the oil under the
effects of nitrogen fertilizer rates were not significantly different from each other and the same behavior of iodine value and refractive index |
