An experiment is carried out by using pots containing 20 kg of slit sand soil collected from one location in Al- Diwania river of Al-Qadisiya province to study the effect of different levels of DAP fertilizer in contents of leaves of Calotopis procera from phenolic compounds, total chlorophyll and (NPK) % .
The experiment includes the application of four different levels of DAP fertilizer (100,200,300,400) ((18:46NP) kg DAP ha-1 to tree of Calotopis procera after selecting then at one year age as design (CRD). and three replicates ,the concentration of N,Pand K % the phenolic compounds ( Vanillic acid , Epicatechin, P-coumaric , Ferulic acid, Queretin-3- β-glucoside , Rutin) mg g-1 extract and total chlorophyll in leaves are estimated. LSD at level 0.05 show superior of 400 kg DAP ha-1 level on the other levels ,300 kg DAP ha-1 and 200 kg DAP ha-1 compared with 100 kg DAP ha-1 level. The percentage of phenolic compounds such as are increased Epicatechin (137.18,87.20,48.72)% respectively with significant differences .the consecration of P-coumaric in leaves are increased .percentage at (43.82,85.39,92.13)% to the second, third and the fourth levels as compared with the first level ,the high level of 400 kg DAP ha-1 is superiority N,P and K uptake the percentage at (80.99,155.00,65.38) % compared with the first level.

The experiment has been conducted by using pots contain 15 kg of slit sand soil collection from one located in Al- Diwania river, Al-Qadisiya Province. The soil contains 750 sand, 200 silt and 50gm.kg-1 clay, bulk density 1.1 Mg m-3, Ec 2.7 ds.m-1 and pH7.1 , the available N,PandK15,10 and130 mg.kg soil-1 to study the effect of fertigation of urea and organic materials on some growth features and concentration of N,P and K % and calotropin µ.gm-1 in leaves of calotropis procera .
The experiment includes fertigation of urea ,organic materials, and mixed (urea+ organic materials) and the control. with 15 ton. ha-1 of organic fertilizer (Orgno Fert) as design (CRD). After 180 days from germination. The growth features, height of plant, diameter of stem, number of leaves. number of teller and concentration of N,P and K % and calotropin µ.gm-1 in leaves were estimated. LSD show superiority of mixed fertigation (dual) treatment for both practice followed by organic materials and urea respectively are compared with the control. Are increase with percentage of mixed fertigation (75.43, 56.62,58,97,39.94,14.29,38.88 and 37.59) % for height of plant, diameter of stem, number of leaves , number of tellers and concentration of N,P and calotropin in leaves respectively.
