Abstarct: In order to investigate the effect of priming and superabsorbent on yield and some growth indices of maize in different irrigation circuits, this study was conducted in 2019 in the research farm of the Faculty of Agriculture, Shahroud University of Technology in Bastam.This experiment was performed as a factorial split plot in the form of a randomized complete block design with 3 replications. The main factor was the irrigation cycle at three levels: farm irrigation every seven days (optimal farm irrigation), farm irrigation every 10 days and farm irrigation every 14 days. Sub-factors included 2 levels of superabsorbent hydrogel application (zero and 150 kg / ha) and three levels of priming including control, hydropriming and salicylic acid priming hormone (100 ppm). The results of this experiment showed that irrigation, priming and superabsorbent factors had a significant effect on the measured traits including height, electrolyte leakage, relative water content of leaves, chlorophyll a and b, carotenoids, proteins, proline, catalase, soluble sugar, Peroxidase, anthocyanin, grain yield and grain yield components.According to the results of this experiment, with increasing irrigation time, plant height, photosynthetic pigments, relative leaf water content, soluble sugars, number of seeds per plant, number of rows per ear, number of seeds per row, biological yield and grain yield in corn decreasedbut with the use of superabsorbent and priming of corn seeds, the destructive effects of drought stress were reduced, so that with the use of superabsorbent at different levels of irrigation, plant height, relative leaf water content, chlorophyll b, number of seeds per plant, number of rows per Cob, number of seeds per row, biological yield and grain yield increased significantly, also corn seed priming caused a significant increase in grain yield and biological yield of corn, so that the highest grain and biological yield in 7 days treatment Irrigation and priming hormone were observed which were 9668.5 and 20087 kg / ha, respectively. Also, according to the results of this study, hormone priming had a more favorable effect than hydro priming.In a general conclusion baxsed on the results of this study, both priming and superabsorbent factors had a positive effect on grain yield and dry matter content.
