Abstract
A factorial experiment within randomized complete block design (RCBD) was coducted during 2016 to investigate the influence of foliar application organic fertilizer "disper alghum" and growth regulator kt-30 on chemical content , endogenous hormone of young appel trees CV. "Anna". The trees were sprayed with organic fertilizer "disper alghum" was three levels (D) : (0 , 3 , 5 g.L-1) , and growth regulator KT-30 at four levels (K) : (0 , 5 , 10 , 20 mg.L-1) . Foliar application of organic fertilizer D5 (5 g.L-1) gave significantly higher values of the total chlorophyll content in leaves 291.0 mg.100g-1 fresh weight , percentage of nitrogen content in leaves 2.25 % , percentage of phosphorus content in leaves 0.59 % , percentage of potassium content in leaves 1.953 % , percentage of carbohydrates in the branches 8.377 % , and the ratio of carbohydrate to nitrogen in branches (C/N Ratio) 7.877 % , cytokinins materials like hormone in leaves 717.6 ppm , the percentage of nitrogen content in the branches showed significantly higher values in organic fertilizer D3 (3 g.L-1) 1.19 % . Foliar application of growth regulator K20 (20 mg.L) gave significantly higher values of the total chlorophyll content in leaves 327.4 mg.100g-1 fresh weight , percentage of phosphorus content in leaves 0.618 % , percentage of potassium content in leaves 2.039 % , percentage of carbohydrates in the branches 9.349 % , and the ratio of carbohydrate to nitrogen in branches (C/N Ratio) 7.818 % , cytokinins materials like hormone in leaves 847.5 ppm . K10 (10 mg.L) significantly incrase percentage of nitrogen content in leaves 2.30 % . There are non-significant value of percentage of nitrogen content in the branches all levels of growth regulator . The interaction treatment D5K20 significant increased total chlorophyll content in leaves , percentage of phosphorus content in leaves , percentage of potassium content in leaves , percentage of carbohydrates in the branches , cytokinins materials like hormone in leaves , other details are significant value in other interaction treatment non-control , there are non-significant value of percentage of nitrogen content in the branches in all interaction treatment of growth regulator 
Highlights
Wheat is at the forefront of the world's strategic crops because its nutritional importance, which is a food source for more than 35% of the world's population. the most important grain crops, and covers the largest area planted on the surface of the earth,and it is the first crop in Iraq in terms of area and production and farm income
Each farm includes the first part and the other part or the other parts.Each technological package has equal space ؛data were collected through farmer interviews andduring harvest, a metric harvest 2was conducted,as shown in the table 1 .Marginal profit function variables have shown a significant difference in profit and income from one package to another
2 Method approved by the Ministry of Agriculture to estimate the productivity of dunums. 3The technology is applied according to its due date
Summary
Wheat is at the forefront of the world's strategic crops because its nutritional importance, which is a food source for more than 35% of the world's population. the most important grain crops, and covers the largest area planted on the surface of the earth,and it is the first crop in Iraq in terms of area and production and farm income. Each farm includes the first part (traditional agriculture) and the other part or the other parts (planting using technological packages).Each technological package has equal space ؛data were collected through farmer interviews andduring harvest, a metric harvest 2was conducted ,as shown in the table 1 .Marginal profit function variables have shown a significant difference in profit and income from one package to another. This difference is the result of the difference in the productivity of dunum of wheat.
