چکیده [English]

In order to investigate the effects of foliar application with plant growth promoters on morphological characteristics of maize (single-cross 704), an experiment with three replications and sixteen treatments conducted with priming and spraying of growth promoters (Organser, Mas-raiz, Dulzee and Control)  as factorial based on complete randomized block design. Analysis of variance showed that the traits including height and stem diameter, the number of internodes in stem, percent of protein, protein yield, index of protein, percent of moisture, dry and wet weight of hay, cob dry weight, cob diameter and total yield of corn were significant (p ≤ 0.05) affected by studied factors., the highest height, number of internodes, corn and cob diameter, percent of protein, protein yield, index of protein, maize and cob dry weight and fresh fodder weight were obtained from use of Dolzee growth promoter. In compared with control, Mas Raiz and Organser growth promoters also cause significant differences in morphological characteristics and corn yield, but this increase was less than Dolzee. There were significant differences between different methods of using growth promoter on corns. The highest increases between treatments were achieved by using of priming + spraying promoter. Application of different ways of consumption all growth promotion on corn yield and harvest index in terms of statistically significant difference did not show.
