This experiment was carried out in the green-house of the Department of Agriculture, with a percentage of 50% shading, located at latitude (35.456) and longitude (44.388), Kirkuk during the period from 1/6/2020 to 1/6/2021 in order to monitor the growth of the hybrid rose plant during a whole year. In the city of Kirkuk and observing the effect of the study of magnetized water and spraying with humic acid on the vegetative and flowering growth characteristics of Elida rose plant. Humic concentration (0, 2.5 and 5) g L-1 and by four sprays. The experiment was carried out using the RCBD randomized complete block design with three replications, and one experimental unit contained two plants. The plants were bred on three flowering stems in the spring season. The results showed the superiority of plants treated with two intensity of magnetized water (900, 1800 gauss) in the characteristic of the number of days required for flowering diameter Flower, flower weight with holder, Vase life, which reached 65 days, 54.6 days, 5.53 cm, 5.83 cm, 8.60 g, 11.98 g, 9.33 days, 13 days), while the results showed the superiority of plants treated with powers of 1800 gauss only in the character of the length of the holder. Syphilis, which reached 55.83 cm. The concentration of 5 g.L-1 was significantly superior to the characteristic of flower diameter, flower weight with length flower stalk, and it was 5.56 cm, 10.42 g. The results showed the superiority of plants treated with both concentrations of humic acid (2.5, 5 g L-1 ) in Vase life, which reached 9.66 days, 11 days, respectively
