The test was conducted in 2021-2022 at the Horticulture and Landscape Department fields - agriculture collage – Diyala University. The study was to examin the result of foliar spray through nano and chelated copper on the growth and production of broccoli hybrids. The foliar spray was used at three levels (0 mg.L-1, 10 mg.L-1, 20 mg.L-1, 40 mg.L-1) whereas five cultivars (v) of broccoli were used and these are: Jassmine (V1), 2004 (V2), Zen (V3), Masturi (V4), and Danar (V5). The results have shown that foliar application of nano copper has significantly affected on the crop growth and production. The highest production was 67.82 t.h-1 and and most of the vegetative and fruitful growth traits were at a concentration of nano-copper 20 mg.L-1. Whereas the results of the effect of foliar spray on broccoli varieties, the V2 has the highest florets 1.363 kg and the total yield was (56.81 h-1) and the chlorophyll index in the leaves was 0.801, and the florets content of carbohydrates, the Danar variety excelled in the leaf area, which amounted to 175.49, while the Matsuri variety excelled in the height of the plant, with an average height of 98.55 cm.
