The experiment was carried out in the vegetable field of the Department of Horticulture and Landscape during the winter agricultural season 2019-2020. The study aimed to investigate the effects of organic fertilization (Tecamine Max) at a concentration of 4 ml.L-1 and chemical fertilization with compound fertilizer N25P5K10 at average of 400 kg.ha-1 and a mixture of the two mentioned fertilizers in different levels. In addition to examine the comparison treatment in the vegetative growth and yield of broccoli. The study included 6 treatments implemented in the field using Randomized Complete Block Design RCBD with three replications. The results showed that all fertilizing treatments achieved the significant differences compare to control treatment in all studied vegetative growth traits. In general, combination of 100 kg chemical fertilization. ha-1 + 7 ml.L-1 of organic extract (Tecamine Max) showed the best values in both of head weight and the heads yield (459.72 g.plant-1 and 28,732 t. ha-1) respectively.
