In order to study of hydropriming, planting depth and nitrogen split application effect on yield and yield components of double cross hybrid of corn, an experiment was carried out as factorial based on randomized complete block design (RCBD) with four replications. Nitrogen split application included (400 kg/ha at sowing date, 100 kg/ha at sowing date and 300 kg/ha 25 to 50 days after sowing date, and 100 kg/ha at sowing date, 150 kg/ha 25 to 50 days after sowing date and 150 kg/ha 50-70 days after sowing date) as first factor, hydropriming levels included (prime and non prime) as second factor and planting depth included (5 and 10 cm soil depth). Results showed that hydropriming and nitrogen split application affected of grain yield, biological yield, 1000-seed weight, number of seed per ear, number of row per ear, plant height, ear length, ear weight, cub weight and cub diameter. All of studied traits except 1000-seed weight and number of seed row per ear affected significantly by planting depth. Interaction between hydropriming and nitrogen split application significantly affected grain yield, biological yield, 1000-seeds weight, plant height and ear weight.
