ABSTRACT


The effects of nitrogen fertilizer on the yield components and stem shearing strength of three canola (Brassica napus L.) varieties Okapi, Opera, and Zarfam were conducted in 2008. The amount of nitrogen fertilizer and variety had significant effect on plant height and biomass yield (P < 0.01), and only variety had significant effect on the length of petiole and siliques at 1% confidence (RCBD analyses with LSD 5% for means). Nitrogen fertilizer had no influence on the amount of seeds in canola siliques. Increased nitrogen fertilizer application enhances plant taller with lower stem diameters while, shearing energy will be decreased. There was no relationship between the cellulose content of the stem piths and level of nitrogen fertilizer. The Opera variety and the serrated knife yielded higher shearing strengths and shearing energy than others and knife tilt angle had significant effects on the stem shearing.

Key words: Canola, Yield, Silique, Stem shearing, Nitrogen.
