Abstract

In order to determine the effects of water deficit and different nitrogen rates on YIELD, YIELD components and physiological traits in RAPESEED, a field experiment was conducted using a factorial split-plot in randomized complete block desing in 2005 growing season. In this study, two cultivars (Zarfam and Modena) in three irrigation levels (irrigation after 40, 60 and 80 percent evacuation of soil water) and four nitrogen rates (0,75, 150 and 225 kg/ha) were studied. Results showed that decreasing soil water and nitrogen rate, caused sever stress that caused significant decreasing in YIELD and YIELD components, that in this case, decreasing the pods per plant (59.17%) was greater than the other components. Physiological traits like STOMATAL CONDUCTANCE (68.89%), leaf relative water content (16.37%) and chlorophyll content (29.61%) decreased in water deficit condition, whereas PROLINE content increased significantly, that this increasing was for higher ability of osmotic adjustment in water deficit condition. By increasing nitrogen rate, all of the physiological traits showed significant increasing too. By contrasting the two cultivars, defined that the Zarfam had a higher tolerance to water deficit condition and lower nitrogen consumption, that the reason of these were higher physiological performances such as STOMATAL CONDUCTANCE, leaf relative water content, chlorophyll and PROLINE in water deficit and nitrogen consumption conditions. Also, this variety had a high potential of production in normal irrigation and high nitrogen consumption.
