This investigation was carried out during October 2016 to February 2017 at Grdarasha field ,College of Agriculture University of Salahaddin ,Erbil to study the effect of 5 water levels of triple super phosphate (TSP ) (0,50,100,150 and 200 kg ha-1) and two levels of KCl (0,150 kg ha-1) which equivalent to (0 ,11.25,22.5, 33.75 and 45 g TSP plot-1), (0 and 33.75 g -1KCl) per plot respectively and their interaction on growth and yield of broccoli (Agassi F1 hybrid), using Randomized Complete Block Design (RCBD) with 4 replicates. The constant amount of urea (100 kg ha-1 which equivalent to 11.25 g) urea per experimental unit was added to each experimental unit. Significant differences were observed for all the studied traits. The highest yield (23.15 Mg ha-1 was recorded from P4 treatment, while the lowest was (14.50 Mg ha-1) obtained from control treatment (P0). Also, the application of potassium caused significant increase in broccoli yield; the lowest and highest values were (17.24 and 19.08 Mg ha-1) recorded from K0 and K1 treatments respectively. The highest values of interaction (74.3, 75.6 and 76.2) SPAD were recorded from K1, P3 and P3K0 respectively. Leaf contents of macro and micro nutrient were recorded a significant difference with interaction effect of both Potassium and Phosphorus, the highest level of concentration recorded was on P4 and K1 at (37.80, 3.98 and 2.25) for Nitrogen, Phosphorus and Potassium respectively.
