Abstract: The experiment was conducted at the research station of the Faculty of Agriculture and Marsh of Thi Qar University during the growing season (2022-2022). Orange seedlings were obtained. Citrus aurantium, one year old, grown as uniformly as possible, from a nursery in Diyala governorate in 2022, and the seedlings were transplanted into 10 kg plastic pots (26 cm diameter) filled with a growing medium mixed with soil and peat moss. The plant care process was carried out in a similar manner throughout the study period, including pruning, weeding, fertilization and irrigation. The study was conducted as a two-factor factorial experiment using a randomized complete block design (R.C.B.D.). The first factor represented the spraying of composite nanofertilizer NPK at three concentrations (1, 0.5, 0) g.L-1, and the second factor represented the spraying of humus at three concentrations (0, 1, 2, ) g.L-1. The interval between one spraying and the next was 3 sprayings with an interval of two weeks. The results of the study can be summarized as follows: The spraying treatment of nanofertilizer NPK showed a positive effect on most of the active ingredients in bitter orange plants. The spray treatment with 100 mg L-1 concentration significantly outperformed the total sugar, naringenin, limonene, terpenes, and pyran compounds by 0.793%, 59.00%, 2.967%, 15.468%, and 7.954%, respectively. The average organic fertilizer spray treatment showed positive effects on most nutritional and chemical parameters of bitter orange seedlings. Citrus aurantium. The spray treatment with 2 g L-1 concentration had a better effect, with the highest proportions of total sugar, naringenin, limonene, terpenes, and pyran compounds, which were 0.760%, 55.28%, 2.772%, 15.086%, and 7.903%, respectively. The interaction coefficient between the two examined factors had a significant positive effect on most of the examined phytochemical and chemical properties. The interaction coefficient between 100 ml L-1 nano-NPK concentration and 2 g L-1 humus concentration recorded the best results for the active ingredient indicators such as naringenin, limonene, terpenes, and pyrans..
