In order to evaluate the seed yield and qualitative traits and oil in some winter rapeseed (Brassica napus L.) varieties as affected by micronutrient elements, this experiment was performed during 2011 - 2012 cropping seasons as split plot arrangement in randomized complete block design with three replications, in Arak, Iran. Micronutrient fertilizers including of Zero as check, Fe, Zn, Mn, Fe + Zn, Fe + Mn, Zn + Mn, Fe + Zn + Mn as main plot and rapeseed varieties including of Zarfam, Okapi, Modena and Licord as sub plot, comprised the experimental factors. The results showed that Okapi variety had the highest seed yield as affected by check (4194 kg/ha) and Zn + Mn (4011 kg/ha) treatments, respectively. In this research, Licord variety showed the highest seed content of Zinc at check and Fe + Mn treatments. The greatest seed content of copper obtained in Modena variety and Fe + Zn treatment. The greatest seed content of iron was shown in Modena vatiety, Fe and Fe + Zn treatments. Also, the highest seed content of manganese obtained in Modena variety and Zn + Mn treatment. In general, Zn + Mn treatment increased seed yield and oleic acid in Okapi variety. Hence, these treatments could be recommendable in Arak region and similar agroclimatic conditions.
