Effect of Foliar Application with Bio-Stimulator Grow Amine " " and Nutrient Solution Disper Complex on Some Growth " " Characteristics and Chemical Content in Olive

Abstract

The experiment was conducted at University of Anbar, during March 2019 to May 2020 to investigate the effect of foliar spray with bio-stimulator "Grow Amine" with concentrations 0, 0.75 and 1.5g.l and nutrient solution "Disper Complex GS" with concentrations 0, 1.5, 2.5 -1 and 3.5 g.l on growth traits and chemical content in olive young trees cv.k18. The spray with Grow Amine" at 1.5 g.l had achieved the highest -1 " -1 values for all vegetative characteristics and mineral content of leaves (N, P, K, Fe, and Zn) in comparison with control. Spray Disper Complex " GS at 2.5 g.l has resulted in maximum value of vegetative traits and N, P, K and for Fe, and Zn spray of Disper Complex GS at 3.5 g.l showed " -1 " " -1 a significant differences from all concentrations.
