Abstract
An experiment was conducted in the lath house in the Department of Horticulture . College of Agriculture,University of Baghdad. Seedlings one and half year of Aloe vera plant were planted in plastic pots filled with sandyloam soil. The research contained two separate experiment. In the first experiments, nitrogen fertilizer was used as urea CO(NH2)2 46% applied to the soil at a rate of:0,0.5,1.0,1.5 g/ plant or as afoliar spray at a rate of :0,1,2,3 g / L. Second experiment was used to study namber of sprays of cycocel at a rate of (0,500,1000,1500) mg./L The experimental results showed that nitrogen at the rate of 3 g / L. significantly increased in the character of the number of leaves and the width and thickness securities amounted to 2.500, 3.190 mm, 2.49 mm and the treatment of spray concentration 2gm nitrogen in plant height and treatment fertilization 0.5 gm nitrogen in the percentage of carbohydrates and the treatment of spraying N1 in the percentage of carbohydrates and chlorophyll in the leaves. Twice Foliar spray with cycocel at the rate of 1500 mg / L significanty increased the percentage of N in the leaves for 2009 season and total charbohydrates in the leaves for 2010 season . Foliar spray with cycocel at the rate of 500 mg / L four times in the season increased the percentage of potassium in the leaves for both season,while foliar spray with 1000 mg / L cycocel applied four times significantly increased the percentage of total charbohydrates and phousphors for 2010 season.
