Effect of Magnesium and Foliar Spray of Gibberellic and Salicylic Acids on Vegetative Growth Characteristics of Peach (Prunus persica L.) Saplings CV. Miski

This study was conducted in the lath house of Department Horticulture and Landscape Design/ College Agriculture/ Tikrit University during growing season 2017 to investigate effect magnesium application foliar spraying both gibberellic salicylic acids on vegetative growth characteristics peach saplings CV. Miski, aged one year which were grafted Apricot seedlings. Magnesium added three concentrations (0, 50 100 mg.litre-1) labelled as Mg0, Mg1 Mg2 consecutively. The acid sprayed mg.liter-1) GA0,GA1 GA2 Besides with following 200 mg.L-1) SA0, SA1 SA2 All these processes performed starting from April 10 times, a time interval weeks. experiment based split-plot system Randomized Complete Block Design (RCBD) various main plots applied subplots. results showed that addition has positively increased stem diameter, single leaf area, total leaves area per plant relative chlorophyll leaves. height diameter sapling, length branches, sapling result acid. positive saplings’ (leaf concentration leaves). dual or triple interaction treatments between studied factors had most investigated.
