The Effect of Immersing the Bud Cuttings with a Combination of NAA and BA Growth Regulators and the Addition of Optimus Plus Nanofertilizer in Improving some Vegetative Qualities of Ber Seedlings Apple Variety

Abstract The study was carried out during the growing season 2022 in one of orchards located Al-Sajla area / Al-Khairat district Holy Karbala governorate On seed Sidr varieties two years old. To find effect immersing bait pens, an apple cultivar treated with a combination growth regulators three concentrations (0, 40 + 20, 80 mg.L -1 ) and symbol (A0, A1, A2) sequence, addition Optimus Pius nano fertilizer m. L its (B0, B1, B2) sequentially overlap between them vegetative traits seedlings, cultivar. experiment according to randomized complete block design (RCBD) as factorial replications. results showed that grafting pen at A1 concentration had significant on (percentage vaccination success, main stem length, diameter, number lateral branches, leaves leaf area) amounted (88.900%, 142.567 cm, 40.047 mm 17.447 branch. Sapling, 827 leaf. 22.567 cm 2 . sapling compared comparison treatment, Ground fertilization nano-fertilizer B2 also led increase amounting 144.900 40.150 mm, 17.667 828 leaves. Seedling , 22.967 treatment. bilateral interaction factors all characteristics seedlings variety, especially when (A1 treatment overlap.
