تاثیر تاریخ کاشت و فاصله ردیف بر عملکرد و اجزای عملکرد ارقام جدید کلزا

In order to study the effects of sowing date, and row spacing on vegetative characters, yield and yield components of New canola, an experifuent was conducted at agricultural research station of Gorgan during 2003-2005. The hperiment was a split plot factorial in a RCBD with 4 replications. Four sowing datJs (17 Oct, 1 Nov, 16 I Nov and IDee) were as main plots and two cultivar (Hyola 420 "RGS- 003) and two row spacing (12 and 24 cm) were subplots in a factorial fonnl Grain yield mean on first and second years of experriment were 2994 , 2277 kglha re1spectivety. With delay of planting reduced grain yield. But this was not significant. First sowing date with 2770 kglha was fourth sowing date with 2513 kglha at most ahd at least grain yield respectivety. Delay of planting by way of reducing of reproductive and vegetative long period was caused number of days to plant muturity reduced. Key words: canola, sowing date, seed rate and row spacing.
