Abstract

To Study the effect of WATER DEFICIT stress and POTASSIUM application on yield and yield components of canola (Brassica napus L.). A factorial split plot experiment with Randomized complete block design was conducted at seed and plant Improvement institute (SPII), Karaj, Iran during 2001-2002. A factorial arrangement of irrigation interval at three levels (Normal Irrigation, cut of Irrigation from flowering stage, cut of Irrigation from seed filling stage) and POTASSIUM fertilizer at three levels (Normal, recommended ratio, double amount of ratio) were allocated to the main plots and cultivars of RAPESEED (Regentcobra, Quantum, Hyola401) were assigned to the sub-plots. The result showed that the main factors (Irrigation levels, POTASSIUM application Levels and Cultivars) had significant effect (P<0/01) on seed yield, seed oil yield, seed weight, Number of seed perpod and number of podper plant. Normal Irrigation had higher yield (and yield components) than cut of Irrigation from flowering stage. Although in this research is has noted that POTASSIUM had important effect on plant resistance to WATER DEFICIT. The interaction effect between Irrigation and POTASSIUM for seed and oil yield and interaction effect between Irrigation and cultivars for seed perpod was significant (P<0/01). The interaction effect between Irrigation, POTASSIUM and cultivar was significant (P<0/01) for oil yield and seed yield.
