Maize had its origin in a semi-arid area but it is not a reliable crop for growing under dry land conditions, with limited or erratic rainfall. Drought can be defined as the absence of adequate moisture necessary for a plant to grow normally and complete its life cycle. Drought occurs every year in many parts of the world, often with devastating effects on crop production. Seed priming is a successful method that has been proved to improve seed germination and emergence of seedlings. The experiment was conducted at the Agricultural Research Station, zahak (in Iran). The field experiment was laid out in randomized complete block design with split plot design with three replications. Seed priming with potassium nitrate solution in five levels (0, 0.5%, 1%, 1.5%, 2%) allocated to main plots and three levels of water stress Include: Control (no stress), Water stress at vegetative stage (5 leaflets) to enter the reproductive phase and Stress at reproductive stage until harvest. Analysis of variance showed that the effect of irrigation and priming on Plant height, stem diameter, Number of leaves, Biological yield Harvest index was significant.
