Abstarct: In order to investigate the effect of methods and different levels of nitrogen fertilization and seed priming on yield, yield components and water consumption efficiency of single crass 704 maize, this experiment was conducted as a split plot- factorial in the period 2016-2017 in the form of a randomized complete block design with three replications in the Damghan pistachio research center. The main factor was the furrow and tape and drip irrigation method. Nitrogen fertilizer levels were considered at four levels: 0, 50, 100, 150 kg nitrogen net per hectare and hydropriming of seeds with two priming surfaces with ordinary water and without priming as factorials. The results of the research showed that nitrogen increase and seed priming under straw irrigation (type) increased grain and biological yield significantly. The highest grain yield with average 5822.15 kg per hectare belonged to drip irrigation method, seed priming and consumption 150 kg per hectare and the lowest grain yield with average 3233 kg per hectare related to furrow and tape irrigation method, the lack of seed priming and non-use of nitrogen fertilizer. The use of nitrogen fertilizer increased 11% of corn length, 15% protein content of grain. The seed priming increased 11% of seed number in corn, 16.6% bush height. Interactive of seed priming and nitrogen fertilizer was meaningful on all morphological traits and biological function. The highest water use efficiency (economical) was 1.2 by straw irrigation and seed priming and used 150 kg of nitrogen fertilizer per hectare.
