Research into the impact of spraying balanced Nano-fertilizer and boron on the vegetative growth characteristics of two hybrids of the cabbage plant, Brassica oleracea var. capitata L., was conducted during the 2021/9/1 agricultural season at the Horticultural Research Station and Landscape - Agriculture College - Tikrit University. There were three variables in this study: the first was the concentration of the balanced Nano-fertilizer NPK (30, 20, 0 gL-1), the second was the concentration of the boron spray (5, 10, 20 mgL-1), and the third was the hybrids (Dlal, Globe Master). Duncan’s multiple range test was utilized for the statistical analysis, with a significance level of 5%. Duncan’s multiple range test with a 5% significance level was used to compare the outcomes. In summary, the study found that spraying the plant with a concentration of 30gL-1 of Nano-fertilizer significantly increased plant height, the number of outer and inner leaves of the head, and the length and width of the longest leaf, while spraying with a concentration of 20mg L-1 gave the highest value in the rate of dry material. Height, number of outer and inner leaves of the head, chlorophyll, and leaf area were all significantly boosted when the plant was sprayed with 5mg L-1 of boron. The hybrid Dlal outperformed the hybrid Globe Master in every growth-related quality tested, especially in terms of leaf characteristics.
