Fruit Characteristics and Yield Quality of Two Apple Varieties As Affected By O DAP Fertilization and Spraying With Moringa Plant Extract

Abstract

This study was carried out in one of the private orchards in the Hashimiya district in Babil Governorate during the 2023 growing seasons to study the effect of the organic O-DAP fertilizer and Moringa leaves extract on the vegetative and chemical characteristics 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 replicates in a randomized complete block design (R.C.B.D). The main plots were represented by the varieties, symbolized by A (the Anna variety and the Sharabi variety), and the spraying with Moringa leaves extract, symbolized by M, as the secondary plots. - Plots at three concentrations (0, 150, 200) ml l-1 and the addition of O-DAP fertilizer, symbolized by D in the sub-sub-plots, and at three levels (0, 500, 1000) gm tree-1, as 27 trees were selected. Each variety is homogeneous in growth and age, and the total of both varieties is 54 trees, and each replicate contains 18 treatments. Each treatment was repeated three times, with one tree per experimental unit (2×3×3). The results were as follows
