| This study was conducted in the Lath house , Department of Horticulture University of Basrah, to investigate the Effect of potassium chloride spraying on some vegetative characteristics and leaves contents of carbohydrates and nitrogen on mango, the plants were sprayed with three concentration of KCl (0 ,0.5 and 1%) twice, the first at 3/5/2012 and the second treatment after two weeks, The result showed the KCl was given a significant effect at 1% concentration at most vegetative characteristics, plant tall, the main and secondary branch, leaf area and number of leaves which reach (79.8cm, 46.2cm, 36.00cm2 and 26.00 leaves) respectively. The KCl treatment at 1% recorded a highest significant mean in carbohydrates, nitrogen and protein contents at leaves and C/N ratio which reached (23.63 mg/g, 1.06% ,6.67% and 22.22) respectivlt. |
