A field experiment was carried out during season 2021 at the Nile experiments station located 10 km east of Hilla city.

in a sandy clay soil mixture, to study the effect of irrigation periods and spraying concentrations of the growth regulator Brassinolide on yield and its components of maize.

the experiment was carried out using a randomized complete block design in the split plot and with three replications.

the experiment included two factors: irrigation periods every 6, 8 and 10 days, main plot and spraying the growth regulator brassinolide at concentrations of 0, 2, 4, 6 and 8 mg.

l-1, sub plot.

the seeds of the Baghdad 3 variety were sown.

the results showed that the irrigation period 6 days was significantly superior in number of ear, number of rows in the ear, number of grains in a row, number of grains in ear, weight of 500 grains, and grain yield, which amounted to 1.60 ear plant -1, 15.96 row ear -1 and 35.44 grain row- 1, 564.9 grain ear -1, 157.73 g and 8.93 ton ha-1 respectively, while the 8 day irrigation period achieved a significant superiority in biological yield amounting to 24.98 ton ha-1.

the spraying concentration also exceeded 8 mg l-1 of Brassinolide significantly increased yield of components the number of rows ear-1, number of grains row-1, number of grains row-1, weight of 500 grains, yield of grains, biological yield, and harvest index, which amounted to 16.36, row ear-1, 34.95, row-1, 573.3, 158.78 g, and 8.63 ton ha -1 27.14 tons ha-1 and 34.45%, respectively.

the interactions showed a significant effect on the studied yield characteristics, and the interaction treatment between the 6 day irrigation period and the spraying at a concentration of 8 mg l-1 gave the highest averages for the yield and its components.
