Abstract: To investigate the effects of planting dates acid salicylic spraying on morphological traits of forage maize hybrids, the Split factorial experiment in completely randomized design with three replications in 1390 was performed. Treatments consisted of two corn varieties containing 704, 504 and 2step application Acid salicylic concentrations (0 and 1 mM) and 3 different planting date (15 July and 5August). In this test the plant height, stem diameter, ear diameter, with cover, distance from ground level to ear, ear number per plant and ear number per square meter were measured. Results obtained showed that plant height, ear diameter, with cover, stem diameter, and the ear of the surface affected by planting date, respectively, at level 1 and 5 percent is significant. Ear diameter covered with 1% probability level is affected by salicylic acid and hybrid corn and other traits showed significant differences in the impact of these treatments had no significant effect. These results show that the best planting date, the second planting date and the appropriate concentration was of 1 mM Acid salicylic and hybrid corn is 704.
