The current study was included the separation and identification of many volatile oil compounds from the seeds and peels of the fruit of Iraqi Citrullus colocynthis (L.) Schrad Plant , by using Clevenger apparatus for light compounds and the results were confirmed by using GLC technique The volatile compounds were identified which included the following : (α-pinene, Limonene, Camphene, Carvacrol, Camphor, P-cymene, Terpinene, Linalool, Menthol, Sabinen and phellanodrene), Terpinene was the highest compound concentration in the seeds and peels (12.14,16.58)% respectively , whereas the lowest concentration in the seeds and peels was Menthol (0.08,0.14) % respectively. The study was also included studying the antioxidant effect of volatile oil separated from the seeds and peels at different concetrations and compared them with the ascorbic acid as a control sample, it was observed that the separated volatile oils from the peels were significantly superior of the free radical inhibition of DPPH (76.1,76.8) % at a concentration (300, 400) Mg.ml–1 respectively compared to the separated volatile oils from seeds

The experiment was carried out in the wooden canopy of the Department of Horticulture and Landscaping – College of Agriculture – Tikrit University for the autumn season 2021 , the experiment included studying the effect of tow overlapping factors , the first being spraying with chemical fertilizer NPK ( 0 , 1.5 gm L-1 ) and the second factor included the spraying of compost tea fertilizer ( poultry manure extract ) at levels ( 0 , 50 , 100 gm L-1 ) . The experiment designed by randomized complete block design ( RCBD ) with three replicates , the results showed the superiority of plants that were sprayed with chemical and organic fertilizers over plants that were not sprayed with either of them . The superiority of spraying with chemical fertilizer NPK at the level of F1 ( 1.5 g L-1 ) in plant height cm , number of leaves leaf plant-1 , leaf area cm2 , number of flowers flower plant-1 , weight of flowers mg , as it gave the highest values reached ( 69.25 cm , 2729.37 leaf plant-1 , 792.87 cm2 , 492.99 flower plant-1 , 0.529 mg ) straight , the lowest values were for the comparison treatment . Also , the same treatment outperformed in the mineral content of the plant , the percentage of volatile oil and the active ingredients . Also , the treatment of spraying with compost tea was superior in the mentioned characteristics at the level of E2 ( 100 g L-1 ) . The results of the interaction showed that there were significant differences in which the treatment was distinguished F1E2 ( 100g L-1 poultry offal extract + 1.5 g L-1 NPK ) it gave the highest values for the traits ( plant height 71.84 cm , number of leaves 2978.30 leaf plant-1 , total leaf area 862.92 cm2 , number of flowers 525.44 flower plant-1 , weight of flowers 0.556 mg flower-1 , N 2.520% , P 0.396% , K 2.020% , volatile oil 4.52% , Cymen 13.414 mg , Myrcene 3.129 mg , Sabinen 3.319 mg ) , the comparison treatment F0E0 gave the lowest values for the mentioned traits , which amounted to ( 57.41 cm , 2179.20 leaf plant-1 , 546.54 cm2 , 428.56 flower plant-1 , 0.418 mg flower-1 , 2.346% , 0.296% , 0.997% 3.47% , 11.622 mg , 1.407 mg , 1.508 mg ) straight .
