Abstract
To study the effect of water deficit and N fertilizer on some morphological traits, yield and yield components of sunflower cv. Progress, a study was carried out as a split plot experiment based on a Randomized Complete Block Design with three replications in research field of Islamic Azad University, Birjand Branch, Iran in 2009. In this study, the irrigation was the main plot at three levels including supplying 100, 67 and 33% of plant water requirement (PWR) and N fertilizer was the sub-plot at four levels of 0, 60, 90 and 120 kg N/ha. The results of analysis of variance showed that irrigation significantly affected plant height, stem diameter, head diameter, seed number per head
