بررسی اثرات تاریخ کاشت بر خصوصیات زراعی و عملکرد ارقام کلزا

In order to study on the effects of different planting dates on agronomical characteristics and yield of six autumn rapeseed cultivars an experiment was conducted at the Torogh Station in Mashhad. Four planting date (7th September, 23rd September,8th October, 23rd October) and six winter cultivars rapeseed (Cobra, SLMO46, Colvert, Orient, Okapi and Fornax) were compared in splite plot experiment based on randomized complete block design with four replication per treatment.
