A field experiment was conducted in the fields of the Faculty of Agriculture, Tikrit University for the 2019-2020 agricultural season to study the effect of planting distances and the level of nitrogen fertilization and boron on the growth and yield of broccoli in gypsum soil. The study included three factors, the first factor was the distance between plants, and it included four distances (35, 45, 55, and 65 cm) (D1, D2, D3, and D4), respectively. The second factor was the level of nitrogen application, which includes two levels of nitrogen 70 and 140 (kg N ha-1) (N1 and N2), respectively. The third factor was the level of boron addition and it includes two levels of boron, which are (without boron application and 6 kg B. ha-1) (B0 and B1), respectively. Results showed that the nitrogen level N2 gave a clear significant increase compared to the N1 level in dry matter yield (the first cut), reaching (21.58 g. Plant-1), while the first level N1 reached (17.94 g(. Dry matter yield (the second cut) reached (84.39 g. Plant-1) in the second level N2, while in the first level it reached (74.36 g. Plant-1) and the N2 level was significantly superior over N1 level for some indicators of vegetative growth, plant height (cm) and leaf area (cm2). -1) and the number of leaves (leaf-plant-1) and thus the yield increased significantly in this level of nitrogen at the N1 level, as the total yield of floral heads at the N2 level was (25.865 tons. Ha-1) and at the N1 level (22.6 ton ha -1 ). The addition of boron fertilizer at a rate of (6 kg B. ha -1) led to a
