Abstract: The research was carried out in Babil Governorate during the 2023 growing seasons to study the effect of the organic O-DAP fertilizer and Moringa leaf extract on the fruit content and set percentage of the Sharabi variety and the Anna variety at 5 years of age. The treatments in the experiment were distributed using a split-split plot design system with three replications in a randomized complete block design (R.C.B.D). The main plots (Anna variety and Sharabi variety) and spraying with Moringa leaf extract are represented, symbolized by A. The main plots are represented by A, and the secondary panels are represented by Sub-Plots with three concentrations (0, 150, 200) ml liter-1, and the addition of O-DAP fertilizer, symbolized by D. In the Sub-Sub-Plots, at three levels (0, 500, 1000) g tree-1, 27 trees were selected for each variety, homogeneous in growth and age. The total of both varieties is 54 trees, and each replicate contains 18 treatments. Each treatment was repeated three times, with one tree. One for the experimental unit (2×3×3).The results of the experiment showed that fertilizing with O-DAP fertilizer at a level of (1000 g tree-1) had a significant effect on all the studied traits, while spraying with Moringa leaf extract at a concentration of (200 ml l-1) on the two apple varieties had a significant effect on the studied traits such as the percentage of N, P, and K. And Fe, as well as the percentage of protein in the fruits and the increase in the percentage of knots in the two varieties by giving it the highest rate. As for the varieties, the response of the two varieties to the experimental factors was a direct response with the levels and concentrations of the factors, as they significantly affected the traits under study, and the Anna variety excelled in the studied traits compared to the local drinking variety by giving it Highest rates. Also, from the data in the tables, it was shown that the triple interaction between O-DAP fertilizer (1000 gm), spraying with Moringa leaf extract at a concentration (200 ml), and the Anna variety was superior in the percentage of N, P, K, Fe, the percentage of proteins in the fruits, and the percentage of set, which gave the highest rate. Compared to the triple intervention of the treatment of not adding O-DAP fertilizer and not spraying with Moringa leaf extract, the drinking variety gave the lowest rate of the studied traits.
