Abstract :

For evaluating pre winter nitrogen fertilizer (N) applying effects on yield and yield components of nine rapeseed cultivars, three N levels (0, 50, and 100 kg/ha) and 9 winter rape seed cultivars (Licord, Opera, Okapi, Modena, SLM046, Talayeh, Zarfam, Elvise and Ebonita) were arranged in a randomized complete block design based factorial in three replicates in Miyaneh region fields. Results showed that there were significant differences among cultivars in all attributes. Increasing N level did not affect seed number per pod, but increased other attributes. 50 kg N/ha significantly decreased HI and TKW in comparison to control. SLM046 and Elvise cultivars produced the highest and the least seed and oil yield, respectively. Some reasons for higher yield in SLM046 than others, were higher plant height, higher pod per plant, higher seed per pod, and higher TKW and HI. Whereas, lesser TKW and HI caused the least yield in Elvise. However, there was no significant difference between two mentioned cultivars in other attributes. In conclusion, it seemed that remobilization had important role in seed filling in SLM046 but not in Elvise.
