\textbf{Abstract}
\begin{abstract}
\normalsize{
Electric field is one kind of stress, which can affect directly or indirectly the plant exposed to it. The effect of electric and magnetic fields on biological systems and human beings is a subject of considerable concern and investigation. Canola is the world's third largest source of edible oil after soybean and palm oil. Canola yield is very low as compared to its production potential. The aim of present study is evaluation of the effect of electric field to canola plant growing under field conditions. A field experiment was conducted to assess of effect of electric field to canola yield, yield components and some physiological characteristics. This experiment was split plot based on completely randomised block design (RCB) with 3 replications. The main factor consisted of 5 different exposure time (0, 15, 45, 80, 150 sec) and the second factor consisted of 4 electric field strength (2, 4, 9, and \unitfrac[14]{kV}{cm}). An additional treatment was assigned to each replication as control. The results of this study showed that the effect of electric field treatments upon the canola seed (var. SLM046) were more significant in comparison with control treatment. The highest increase in measured characteristics, including height of plant, length of pod, biological yield and seed oil yield with 21, 11, 133 and \mbox{112\,\%}, respectively. This experiment detected that the best result in most of the traits has been shown in 80s and \unitfrac[9]{kV}{cm}. Consequently, it is possible; such induced current in turn sends signals across the cell membrane barrier that produces alterations in intracellular biochemical and physiological functions. However, the crop increase could also be related to the sterilizing effect of high"=voltage application.}
