The experiment was conducted. Field work in one of the fields of Al-Azzawiyah area / Al-Musayyab district, 40 km north of Babylon Governorate During the fall season 2024-2025 to study the effect of foliar spraying. blend from Cysteine ​​and ascorbic acid and their interaction at a concentration of (0, 50, 50, mg. L¹) which is symbolized by T₀, T₁, T₂, and T₂, and the soil addition of organic fertilizer at a concentration of (0, 5, 10 ml. L¹) which is symbolized by (L0, L1, L2 ml. L1) on the growth and yield of broccoli. A factorial experiment was conducted within the RCBD design. In total 36 treatments. The land was divided into three replicates, each replicate containing 12 experimental units. The replicate contained two terraces, width Every bench1 m, leaving a distance of 1 m between one platform and another, and 50 cm between the experimental units as an insulator to prevent mixing between treatments, and 50 cm between one plant and another. And it was Drip irrigation. The results showed that the individual and interaction treatments recorded significant values ​​between Attributes studied. And individual treatmentT₃ achieved the highest significant increase in the number of leaves, which amounted to 65.38 leaves/plant^-1, and the leaf area was 2965 dm/plant^-1. The results also showed a significant superiority in the soil addition treatments, as treatment L2 outperformed by giving the highest value in the number of leaves, which amounted to 62.90 leaves/plant^-1, and the leaf area amounted to 3039 dm/plant^-1. As for the interaction treatments between the study factors, the results showed a significant superiority, as treatment T₃ L2 achieved the highest significant increase by giving the highest value in the number of leaves, which amounted to 71 leaves/plant^-1, and the leaf area amounted to 3842 dm/plant^-1, and the chlorophyll content of the floral disc amounted to 16.38 (mg 1 gm^-1 fresh weight), and the weight of the floral disc amounted to 576 gm/plant^-1.
