Abstract
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.
