بررسی اثرات تراکم کاشت بر خصوصیات زراعی و عملکرد ارقام کلزای پاییزه

In order to study on the effects of planting density on agronomical characteristics and yield of rape seed cultivars an experiment was conducted at the agricultural reseach station of Torogh in Mashhad. Experimental design was split plot in complete randomized block design, with four replications. Main plots consisted on four rape seed cultivars (Esteghlal, Zargol, Shir Ali and SLM046) and four levels of planting density (20, 26.6, 40 and 80 plants persquare meter) were allocated on subplots. A significant differences between cultivars was observed for grain yield, 100 seed weight and plant height. Results showed SLM046 was higher on above mentioned traits.
