Abstarct: The research has been done in the research farm of Shahroud Faculty of Agriculture in format of complete random blocks in four repetitions in 1394 to study the effect of priming and drought stress on the weed growth, and quantitative and qualitative performance of maize.The factors of experiment are including: seed priming in two levels (hydropriming and ultrasonic), drought stress in three levels (7days, 10 days, and 14days), and weeding the third factor weeding in two levels of complete weeding during growth period, and absence of weeding. The results showed that weeding weeds in comparison with not to weed them improves the features under the study, and seed priming causes augmentation in the growth properties, performance and its components, and some qualitative attributes. As a result, drought stress has the meaningful impact on the qualitative attributes of maize.
