In order to study the effect of different planting dates on agronomical characteristics and yield of rapeseed cultivars an experiment was conducted at the Torogh station in Mashhad. Four planting date (7th September, 23rd September,8th October, 23rd October) and Four winter cultivars rapeseed Esteghlal, Shirali, SLM046 and Zargol were compared in splite plot experiment based on randomized complete block design with 4 replication per treatment. Main plots consisted on four rapeseed cultivars and four sowing date were allocated to sub plots. The results indicated that significant differences between cultivars was observed for grain yield, 1000 seeds weight and plant hieght and a significant differences was observed between different planting dates.
