The experiment was conducted in field during the season 2020-2021 at The Al-sayade Research Station of the College of Agriculture/University of Kirkuk, and aimed to study the impact of three types of organic fertilization (without fertilization, sheep fertilizer, organic fertilizer), and three types of Emitter (GR, Turbo, Spiral ) and the interaction between them in the growth and yield of Broccoli ( Brassica oleracea Var.italica ) and the evaluation of the Drip Irrigation System. A factorial experiment was carried out according split split – plot design of the Random Complete Block Design R.C.B.D and obtained data was statistical analyzed by using SAS system and Duncan multi –Range test at the probability level of %5 used to compared among the mean of treatment. The results showed that organic fertilization of sheep fertilizer gave a significant increase in the height of the plant 66.27 cm. The H (250g.d -1 in four stages) fertilizer adding showed a significantly Superiority for traits of the yield of plant and total yield of plant (902.84 g plant -1 and 45.142 ton ha -1 , respectively). However, the treatment without fertilization has given a significant increase of total chlorophyll ratio to 25.44 mg. g -1 .Turboemitter recorded a significant increase in the height of the plant 67.233cm. whereas, the GR emitter showed a significant increase the total chlorophyll ratio by 25.830mg g -1 and superior in percentage of dry material in main head recorded by %12.694. The interaction between H fertilizer and Turbo emitter, had significantly differences of the most of the qualities traits were studied. When evaluating the drip irrigation system, it noted the superiority of the GR emitter treatement was gave the lowest plants the Coefficient of Variation 0.051 % with the highest absolute field emission uniformity reach to 98.84%, the highest efficient water distribution with 98.08% and the lowest water consumption 43.17mm.
